1. Scientific scope
The Journal of Synchrotron Radiation seeks to cover all aspects of synchrotron radiation thus bringing together the full range of interests and skills of the synchrotron radiation community. Contributions are invited within the general areas of instrumentation, methods and applications. Instrumentation articles covering synchrotron radiation sources and beamlines, free-electron lasers, optics, detectors, electronics and data acquisition, and sample chambers and environment are welcomed. Methods and applications articles are invited within the categories of diffraction, spectroscopy and imaging.
2. Categories of contributions
Contributions should conform to the general editorial style of the journal. Typical papers may be viewed by going to //journals.iucr.org/s/sample_issue.html .
2.1. Research Papers
Full-length Research Papers should not normally exceed the equivalent of about 10000 words.
2.2. Short Communications
Short Communications are intended for the presentation of topics of limited scope or for preliminary announcements of novel research findings. They are not intended for interim reports of work in progress, and must report results that are of scientific value in their own right.
Short Communications should not normally exceed two journal pages (about 1500 words). A maximum of two figures and two tables of appropriate size are permitted. They are refereed in the normal way.
2.3. Lead Articles
Lead Articles are authoritative, comprehensive and forward-looking reviews of major areas of research interest. They are always commissioned by one of the Main Editors, on the advice of the Editorial Board. Suggestions for suitable topics and of potential author(s) are welcomed by the Main Editors for discussion with the Board.
The Main Editors will discuss the treatment of the topic, the length of the Article and the delivery date of the manuscript with invited author(s). Lead Articles will be refereed in the normal manner; they will be made open access on publication.
2.4. Feature Articles
A Feature Article is a focused survey covering recent advances in an area of current research. It should not aim to be comprehensive, but a brief introduction should provide historical perspective and a brief conclusion should indicate likely future directions. Inclusion of relevant new results is appropriate.
Feature Articles will generally be about ten journal pages (10000 words). Shorter articles on rapidly evolving areas are also actively encouraged. They will be commissioned by one of the Main Editors, either personally or following a formal proposal by prospective author(s). Feature Articles will be refereed in the normal way; they will be made open access on publication.
2.5. Beamlines
Beamline papers are short descriptive papers providing details of beamlines available to users at synchrotron and free-electron laser facilities around the world. Beamline papers should normally be about three journal pages (about 3000 words) in length. They are refereed in the normal way. For more details of the requirements for Beamline papers, see //journals.iucr.org/s/services/beamlines.html .
2.6. Computer Programs
A brief description of the purpose, strategy, computer language, machine requirements, input requirements and the type of results obtained should be included. It is also ordinarily required that the adequacy of the documentation shall have been proved by the successful use of the program by two different teams outside the author's institution. Authors would usually be expected to be those who developed the program. Computer Programs will generally be about five journal pages (5000 words). Shorter articles on both new programs or systems and significant updates to existing ones will also be considered.
2.7. Laboratory Notes
These are very brief descriptions of special devices, equipment modifications, techniques for accomplishing certain tasks etc. A simple schematic drawing may often be preferable to an actual photograph of the apparatus. These articles should not normally exceed 500 words and may be refereed.
2.8. Teaching and Education
Papers in this category cover all aspects of an educational nature related to the general field of synchrotron radiation. All contributions should be submitted to one of the Main Editors.
2.9. Letters to the Editor
These may deal with non-technical aspects of synchrotron radiation, its role, its propagation, the proper functions of its Societies etc. or may make a technical observation or scientific comment that would usefully be brought to a wider audience. Letters should be submitted to one of the Main Editors.
2.10. New Commercial Products
Announcements of new commercial products are published free of charge. The descriptions, up to 300 words or the equivalent if a figure is included, should give the manufacturer's full address.
2.11. Meeting Reports
These are normally invited. Prospective authors interested in writing such items should first contact one of the Main Editors.
3. Submission and handling of manuscripts
3.1. Submission
Full details of the submission procedure can be found at //journals.iucr.org/s/services/submitbdy.html . Full instructions for submitting an article and details of the files required are given at //journals.iucr.org/s/services/submitinstructions.html . Authors are encouraged to use the templates available from //journals.iucr.org/s/services/helpsubmit.html . Articles will be checked for plagiarism using the CrossCheck service.
In the case of Addenda or Errata to published articles, the article should be submitted to the Co-editor of the original article.
3.3. Quality of writing
Papers should be clearly written and grammatically correct. If the Co-editor concludes that language problems would place an undue burden on the referees, the manuscript may be returned to the authors without review. Details of language-editing services can be found at //journals.iucr.org/services/languageservices.html .
3.4. Handling of manuscripts
The Co-editor to whom the manuscript is assigned is responsible for choosing referees and for accepting or rejecting the article. This responsibility includes decisions on the final form of the article and interpretation of these Notes when necessary.
If changes to a manuscript requested by a Main Editor, Co-editor or the editorial staff are not received within two months of transmittal to the author, the submission will be considered as withdrawn. Should the manuscript require further revision, this would normally be expected to be completed within one month of the revision having been requested. If a manuscript is not acceptable after two revisions it will not be considered further. Any subsequent communication of the material will be treated as a new submission in the editorial process. An article that has been rejected must not be resubmitted to any IUCr journal unless the reasons given for the rejection have been fully addressed in the revised version.
For accepted articles, it is the responsibility of the Managing Editor to prepare the article for publication. This may involve correspondence with the authors and/or the responsible editor in order to resolve ambiguities or to obtain satisfactory figures or tables. The date of acceptance that will appear on the published article is the date on which the Managing Editor receives the last item required. Correspondence will be sent to the author who submitted the article unless the Managing Editor is informed of some other suitable arrangement.
On rare occasions, an editor may consider that an article is better suited to another IUCr journal. Any change to the journal of publication will only be made after full discussion with the contact author.
3.5. Author's warranty
The submission of an article is taken as an implicit guarantee that the work is original, that it is the author(s) own work, that all authors are aware of and concur with the submission, that all workers involved in the study are listed as authors or given proper credit in the acknowledgments, that the manuscript has not already been published (in any language or medium), and that it is not being considered and will not be offered elsewhere while under consideration for an IUCr journal. The inclusion of material in an informal publication, e.g. a preprint server or a newsletter, does not preclude publication in an IUCr journal.
The co-authors of an article should be all those persons who have made significant scientific contributions to the work reported, including the ideas and their execution, and who share responsibility and accountability for the results. Other contributions should be indicated in an `Acknowledgments' section. Changes to the list of authors will normally require the agreement of the editor and all authors.
Important considerations related to publication have been given in the ethical guidelines published in Acc. Chem. Res. (2002), 35, 74–76 and Graf et al. [Int. J. Clin. Pract. (2007), 61(Suppl. 152), 1–26 ]. Authors are expected to comply with these guidelines.
3.6. Copyright
Except as required otherwise by national laws, an author must sign and submit a copy of the Transfer of Copyright Agreement form for each manuscript before it can be accepted. Authors will be asked to transfer copyright during the electronic submission procedure. Details of author rights can be found at //journals.iucr.org/services/authorrights.html . See §13.4 for information on the licensing of open-access articles.
3.7. Author grievance procedure
An author who believes that an article has been unjustifiably treated by the Co-editor may appeal initially to one of the Main Editors for a new review and, finally, to the Editor-in-chief of IUCr Journals if the author is still aggrieved by the decision. The initial appeal must be made within three months of rejection of the article. The decision of the Editor-in-chief is final. Any resubmission to another Co-editor will be forwarded to one of the Main Editors.
3.8. Contact e-mail address
The contact author must provide an e-mail address for editorial communications and despatch of electronic proofs.
3.9. File format
The source files required for an article are: a single file in WORD, OpenOffice or LATEX format of the text, tables and figure captions of the article; a high-resolution graphics file (minimum 600 d.p.i.) in TIFF, PostScript or encapsulated PostScript format for each figure and scheme; and files of any supplementary material. These should be uploaded as described in the online submission instructions .
4. Abstract, synopsis and keywords
All scientific contributions must be preceded by an English language Abstract and a one or two sentence Synopsis of the main findings of the article for inclusion in the Table of Contents. The Abstract should state concisely the principal results obtained.
The Abstract should be suitable for reproduction by abstracting services without change in wording. It should not repeat information given in the title. Ordinarily 200 words suffice for Abstracts of a full-length article and 100 words for shorter contributions. It should make no reference to tables, diagrams or formulae contained in the article. It should not contain footnotes. Numerical information given in the Abstract should not be repeated in the text. It should not include the use of `we' or `I'.
Literature references in an Abstract are discouraged. If a reference is unavoidable, it should be sufficiently full within the Abstract for unambiguous identification, e.g. [Smith (1998). J. Synchrotron Rad. 5, 21–31].
Authors should ideally supply at least five keywords.
5. Diagrams and photographs (`figures')
A set of guidelines for preparing figures is available from //journals.iucr.org/s/services/help/artwork/guide.html . Figures should be prepared using one of the file formats listed in §3.9.
The choice of figures should be optimized to produce the shortest printed article consistent with clarity. Duplicate presentation of the same information in both figures and tables is to be avoided, as is redundancy with the text. Supplementary tables and figures may be deposited (see §12).
In articles which use powder profile fitting or ).
(Rietveld) methods, figures which present the experimental and calculated diffraction profiles of the material studied should also contain the difference profile. As primary diffraction data cannot be satisfactorily extracted from such figures, the basic digital diffraction data should be deposited (see §12.45.1. Quality
Electronic files in the formats listed in §3.9 are essential for high-quality reproduction. The resolution of bitmap graphics should be a minimum of 600 d.p.i.
5.2. Size
Diagrams should be as small as possible consistent with legibility. They will normally be sized so that the greatest width including lettering is less than the width of a column in the journal (8.8 cm).
5.3. Lettering and symbols
Fine-scale details and lettering must be large enough to be clearly legible (ideally 1.5–3 mm in height) after the whole diagram has been reduced to one column width. Lettering should be kept to a minimum; grids and shadings should be avoided where they are not required to improve clarity. Descriptive matter should be placed in the caption.
5.4. Numbering and captions
Diagrams should be numbered in a single series in the order in which they are referred to in the text. A list of the figure captions should be included in the manuscript.
5.5. Colour figures
Colour figures are accepted at no cost to the author provided that the editor agrees that they improve the understanding of the article. Figures printed in greyscale may appear in colour in Crystallography Journals Online .
Authors preparing colour figures should consider how the figure would look if printed in greyscale and to readers who are colour-blind. It is very important that poor contrast (e.g. pale colours with a white background) be avoided.
5.6. Enhanced figures
An online tool for authors to prepare standard and corresponding three-dimensional interactive structural diagrams is available from https://submission.iucr.org/jtkt .
6. Tables
Authors submitting in Word should use the Word table editor to prepare tables.
7. Mathematics and letter symbols
Authors submitting in Word should use the Word equation editor to prepare displayed mathematical equations.
The use of the stop (period) to denote multiplication should be avoided except in scalar products. Generally no sign is required but, when one is, a multiplication sign (×) should be used.
Make sure only scalar variables and non-standard functions appear in italic font.
Vectors should be in bold type and tensors should be in bold-italic type.
Greek letters should not be spelled out.
Care should be taken not to cause confusion by using the same letter symbol in two different meanings.
Gothic, script or other unusual lettering should be avoided. Another typeface may be substituted if that used by the author is not readily available.
All displayed equations, including those in published Appendices, should be numbered in a single series.
8. Multimedia
Multimedia content (e.g. time-lapse sequences, three-dimensional structures) is welcomed. For details of how to prepare enhanced three-dimensional figures, see §5.6.
9. Nomenclature
9.1. Crystallographic nomenclature
Authors should follow the general recommendations produced by the IUCr Commision on Crystallographic Nomenclature (see reports at https://www.iucr.org/iucr/commissions/cnom.html ).
Atoms of the same chemical species within an Chemical and crystallographic numbering should be in agreement wherever possible. When it is necessary to distinguish crystallographically equivalent atoms in different asymmetric units the distinction should be made by lower-case roman numeral superscripts (i.e. i, ii, iii etc.) to the original atom labels.
should be distinguished by an appended arabic numeral.9.2. Nomenclature of chemical compounds etc.
Names of chemical compounds and minerals are not always unambiguous. Authors should therefore quote the chemical formulae of the substances dealt with in their articles.
Chemical formulae and nomenclature should conform to the rules of nomenclature established by the International Union of Pure and Applied Chemistry (IUPAC ), the International Union of Biochemistry and Molecular Biology (IUBMB ), the International Mineralogical Association (IMA ) and other appropriate bodies. As far as possible the crystallographic nomenclature should correspond to the systematic name.
Any accepted trivial or non-systematic name may be retained, but the corresponding systematic (IUPAC ) name should also be given.
9.3. Units
The SI ) is used except that the ångström (symbol Å, defined as 10−10 m) is generally preferred to the nanometre (nm) or picometre (pm) as the appropriate unit of length. Recommended prefixes of decimal multiples should be used rather than `×10n'.
(10. References
References to published work must be indicated by giving the authors' names followed immediately by the year of publication, e.g. Neder & Schulz (1998) or (Neder & Schulz, 1998). Where there are three or more authors the reference in the text should be indicated in the form Smith et al. (1998) or (Smith et al., 1998) etc.
In the reference list, entries for journals [abbreviated in the style of Chemical Abstracts (the abbreviations Acta Cryst., J. Appl. Cryst. and J. Synchrotron Rad. are exceptions)], books, multi-author books, computer programs and personal communications should be arranged alphabetically and conform with the following style:

12.1. Purpose and scope
Parts of some articles are of interest to only a small number of readers, and the cost of printing these parts is not warranted. Arrangements have therefore been made for such material to be made available from the IUCr electronic archive via Crystallography Journals Online or to be deposited with the Protein Data Bank, the Nucleic Acid Database and the ICDD as appropriate.
12.2. IUCr electronic archive
All material for deposition in the IUCr electronic archive should be supplied in one of the formats described at //journals.iucr.org/services/filetypes.html .
Examples of non-structural information that may be deposited include:
Structural information (for small-molecule structures) should be supplied in
format; structure factors should be supplied as .fcf files.Authors are encouraged to submit chemical connectivity (MOL, CML, CHM, SMI) files of reported structures with their articles. These files will be made available as part of the supplementary materials for each article and will be used to provide InChI (International Chemical Identifier) keys for the article, making the structures easier to find in the chemical literature.
12.3. Macromolecular structures
Authors should follow the deposition recommendations of the IUCr Commission on Biological Macromolecules [Acta Cryst. (2000). D56, 2 ]. For all structural studies of macromolecules, coordinates and the related experimental data (structure-factor amplitudes/intensities and/or NMR restraints) must be deposited at a member site of the Worldwide Protein Data Bank (https://www.wwpdb.org/ ) if a total molecular structure has been reported. Authors are encouraged to deposit their data with the wwPDB in advance of submission to the journal and to provide an mmCIF and a wwPDB validation report on submission. Authors must supply the wwPDB reference codes before the article can be published.
12.4. Powder diffraction data
Authors of powder diffraction articles should consult the notes provided at //journals.iucr.org/services/cif/powder.html .
