notes for authors
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.
Contributions should conform to the general editorial style of the journal. Typical articles may be viewed by going to http://journals.iucr.org/s/sample_issue.html.
Full-length Research Papers should not normally exceed the equivalent of about 10000 words.
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). They are refereed in the normal way.
Lead Articles are authoritative, comprehensive and forward-looking reviews of major areas of research interest. Suggestions for suitable topics and of potential author(s) are welcomed by the Editors.
The Editors will discuss the treatment of the topic, the length of the Article and the delivery date of the article with invited author(s).
Feature Articles are focused surveys covering recent advances in an area of current research. 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 be about ten journal pages (10000 words). Shorter articles on rapidly evolving areas are also actively encouraged.
Topical Reviews aim to capture the current trend of a field and are expected to be relatively short. Typically they should contain about 6000 words and a maximum of 50 references, with half of those having been published in the last three years.
These brief articles provide details of beamlines available to users at synchrotron and free-electron laser facilities around the world. Beamline papers should provide an overview to allow potential users to understand the beamline capabilities and sufficient details to act as an archival reference for research performed on the beamline. Where possible, beamline articles should emphasize what makes the beamline distinct from others. Articles in this category may also describe certain parts of a beamline that give it unique features, e.g. an insertion device, beamline optics, experimental station, sample environment or detector. Results of measurements at the beamline should be presented. Beamline papers are refereed in the normal way.
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.
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.
Articles 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 Editors.
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 Editors.
Scientific Commentaries discuss articles of particular importance for the readership of the journal. Suggestions for suitable topics and of potential author(s) are welcomed by the Main Editors.
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.
These are normally invited. Prospective authors interested in writing such items should first contact one of the Editors.
This section contains details of meetings of scientific societies, congresses, summer schools etc. that are of interest. Contributions should be sent to the Editorial Office in Chester.
Articles should be submitted at http://journals.iucr.org/s/services/submit.html. Full instructions for submitting an article and details of the files required are given at http://journals.iucr.org/s/services/submitinstructions.html. Authors are encouraged to use the templates available from http://journals.iucr.org/s/services/helpsubmit.html.
The contact author must provide an e-mail address for all editorial communications and despatch of proofs and electronic reprints.
The source files required for an article are: a single file in WORD, OpenOffice or LaTeX format of the text, tables and figures of the article; a high-resolution graphics file (minimum 600 d.p.i.) in TIFF, PostScript, encapsulated PostScript or PNG format for each figure and scheme; and files of any supporting information. These should be uploaded as described in the online submission instructions.
Each article is handled by an editor chosen by the author from a list of those available at the time of submission. Authors should choose an editor whose area of expertise most closely matches the subject of the article. Details of the current Editorial Board can be found at http://journals.iucr.org/s/services/editors.html.
All contributions will be seen by referees (normally two) before they can be accepted for publication. The editor to whom the article 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. Further information on the peer review process can be found at http://journals.iucr.org/s/services/peerreview.html.
Changes to an article requested by the Editors, Co-editor or the editorial staff should be received within two months of transmittal to the author, otherwise the submission will be considered as withdrawn. If an article 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.
After initial submission, any revised or new files should be uploaded only in response to a specific request from an editor.
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. Contact details for the Managing Editor of Journal of Synchrotron Radiation can be found at http://journals.iucr.org/services/contactus.html.
On rare occasions, an editor may consider that an article is better suited to another IUCr journal. Any change to the section or journal of publication will only be made after full discussion with the contact author.
Articles will be checked for plagiarism using the CrossCheck service.
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 acknowledgements, that the article 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 the acknowledgements. Changes to the list of authors will normally require the agreement of the editor and all authors.
The IUCr is a member of COPE (Committee on Publication Ethics) and endorses its recommendations, including the Code of Conduct for Editors, which are available at http://www.publicationethics.org/ . 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.
Further details of the ethical policies of IUCr Journals can be found at http://journals.iucr.org/services/ethicalpublishingpolicy.html.
An author who believes that an article has been unjustifiably treated by the Co-editor may appeal initially to one of the 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.
Except as required otherwise by national laws, an author will be required to agree to the transfer of copyright before an article can be accepted. Authors selecting open access do not need to transfer copyright. Details of author rights can be found at http://journals.iucr.org/services/authorrights.html.
Authors are given the opportunity to make their articles `open access ' on Crystallography Journals Online. Authors of open-access articles will not be asked to transfer copyright to the IUCr, but will instead be asked to agree to an open-access licence. This licence is identical to the Creative Commons Attribution (CC-BY) Licence . Further details can be found at http://journals.iucr.org/services/openaccess.html.
Articles should be clearly and simply written so that they are accessible to as broad a readership as possible. Before preparing articles, authors should consult a current issue of the journal to make themselves familiar with the general format, such as the use of headings, layout of tables and citation of references. A sample issue is available at http://journals.iucr.org/s/sample_issue.html.
The title of the article should be written to appeal to a wide audience and should include key phrases in the subject area. The use of acronyms or abbreviations should be avoided.
All contributions must be accompanied 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. Authors should also supply at least five carefully selected keywords. These may include synonyms and specific phrases related to the subject of the article.
The Abstract should state as specifically and as quantitatively as possible the principal results obtained and their broad significance. For Research Papers, Lead Articles or Feature Articles the Abstract should be around 250 words. For shorter contributions 150 words should suffice. The Abstract should be suitable for reproduction by abstracting services without a change in wording and should not repeat information given in the title. It should make no reference to tables, diagrams, atom numbers or formulae contained in the article. It should not contain footnotes and should not include the use of `we' or `I'.
It is important that articles are well written and grammatically correct. If the Co-editor concludes that language problems would place an undue burden on the referees, the article may be returned to the authors without review. Details of language-editing services can be found at http://journals.iucr.org/services/languageservices.html.
A set of guidelines for preparing figures is available from http://journals.iucr.org/s/services/help/artwork/guide.html. Figures should be prepared using one of the file formats listed in §3.2 and should be included in the article at the point they are first mentioned.
The choice of figures should be optimized to produce the shortest 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 figures may be deposited (see §5.2).
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).
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.
Diagrams should be numbered in a single series in the order in which they are referred to in the text.
Figures in colour are accepted at no cost to the author. Authors preparing colour figures should consider how the figure would look 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.
An online tool for authors to prepare standard and corresponding three-dimensional interactive structural diagrams is available from http://submission.iucr.org/jtkt.
Authors submitting in Word should use the Word table editor to prepare tables.
Extensive numerical information is generally most economically presented in tables. Text and diagrams should not be redundant with the tables.
Multimedia content (e.g. time-lapse sequences, three-dimensional structures) is welcomed. For details of how to prepare enhanced three-dimensional figures, see §6.1. The preferred file formats for multimedia are given at http://journals.iucr.org/services/filetypes.html.
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.
Scalar variables and non-standard functions should appear in italic type.
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.
The International System of Units (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'.
Authors should follow the general recommendations produced by the IUCr Commission on Crystallographic Nomenclature (see reports at http://www.iucr.org/iucr/commissions/cnom.html).
Atoms of the same chemical species within an asymmetric unit should be distinguished by an appended arabic numeral. 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.
Chemical formulae and nomenclature should conform to the rules of nomenclature established by the International Union of Pure and Applied Chemistry (IUPAC ), 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.
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.
The reference list should be arranged alphabetically and conform with the following style:
