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 n.s-1.cm-2 at the sample position. A compact curved 2D position sensitive detector will allow simultaneous acquisition of 120 degrees in 2θ, with ∼ 106s-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). © The Authors
