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

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 tip to approximate to 10(8) ns(-1) cm(-2) at the sample position. A compact curved 2D position sensitive detector will allow simultaneous acquisition of 120 degrees in 2 theta, with approximate to 10(6) 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).
