Quokka

Characterisation measurements are continuing on the instrument and a call-for-proposals is anticipated shortly.

The graph above shows SANS from the mineral opal illustrating power-law behaviour. The inset shows the original 2D data set from which the reduced SANS was derived and illustrates how Quokka’s detector can be offset to increase the Q range covered by a single measurement. The maximum flux at the sample position has been estimated to be 3 x 10⁷ n cm^-2s^‑1.
