D4 Diffractometer for liquids at the ILL, installed on the hot source.
The dedicated liquid and amorphous instrument D4 is a two-axis diffractometer
equipped with nine 1D position sensitive microstrip detectors. In this model,
a PSD banana detector is also present.
The monochromator take-off angle is 2Theta_M ~ 20-25 deg, variable. The available
monochromators are all vertically focusing, Cu (200) for 0.7 Angs, Cu (220)
for 0.5 Angs.
Cu 002 DM=1.807 AA
Cu 220 DM=1.278 AA
Parameters in boldface are required;
the others are optional.
