Rapidly tunable monochromator

This instrument (station 9.5) is currently under development (figures 5.17 and 5.18) at Daresbury on the wiggler line for macromolecular crystallography (Thompson and Helliwell 1986 Brammer 1987 Brammer et al 1988 Habash et al 1990). It is primarily intended for very rapid Laue and rapidly tunable monochromatic experiments. The sample position is at 32m from the tangent point. A point focussing mirror is situated at 18m and a rapidly tunable monochromator at 30m (in the hutch). 

Extremely quiet and rapid monochromators are now available from numerous vendors. As covered in detail in Chapter 2, top-notch monochromators (grating and interferometer), diode arrays, accousto-optic tunable filters, as well as modern interference-filter instruments now exist. Fiber optic probes, multiple detector modules, and transmission attachments all lend themselves to superior sample handling of powders and solid dosage forms.
