Echidna and Wombat
Echidna (high-resolution powder diffractometer)
New flight-path shielding has been installed (see below). This new design optimised for the beam geometry resulted in an increase of the neutron flux by 2.5 at the sample position. 
Wombat (high-intensity powder diffractometer)
One of the most important uses envisaged for Wombat is to measure how materials change structure in real time. As part of the instrument commissioning a standard lithium-ion battery, initially charged, was slowly discharged and recharged over a 60 hour period. Diffraction patterns were acquired every five minutes; this 3D image shows the full time history. The image shows the contraction and expansion of the carbon anode as the lithium moves in and out of the structure.
