Wombat: the high-intensity powder diffractometer at the OPAL reactor

Abstract

The Wombat powder diffractometer will be located on the TG1 thermal guide at the OPAL reactor. A variable vertically focusing monochromator will provide a flux of up to ≈108 ns−1 cm−2 at the sample position. A compact curved 2D position sensitive detector will allow simultaneous acquisition of 120 ° in 2θ, with ≈106 s−1 count rate capability and time resolution down to the microsecond level. Wombat is designed for experiments requiring rapid real time acquisition (time-resolved environmental or kinetics experiments) or very good signal to noise (experiments with difficult sample environments or small sample volumes).
