Figure 6
A schematic presentation of the instrument ID1 at the ESRF. Synchrotron radiation from an undulator, monochromated by an Si(111) double-crystal monochromator, enters the hutch through a Be window. For wet samples the soft X-radiation passes through a helium-filled tube of length 1.5 m. No helium path is required for samples which are stable in vacuo. The CCD camera can be operated both in vacuo and at atmospheric pressure. The diameter of the cylindrical vessel is 2.6 m. The diffractometer (not shown) occupies the bulk of the volume of the vessel. |
