Ancillary equipment
First testing of sample-environment equipment on Wombat
A 0-1600°C vacuum furnace (Institut Laue-Langevin type) is shown below, mounted for the first time on the Wombat high-intensity powder diffractometer for commissioning experiments. The design of a 2nd furnace, with the ability to undertake studies at high temperature under a variety of different gas types is close to completion. Delivery is expected later this year. 
Testing of the 20-position sample changer for the Quokka small-angle neutron scattering instrument.
Based on a design at the NIST facility (National Institute of Standards and Technology, Centre for Neutron Research) in the USA, a 20-position sample changer, heated and cooled via a Julabo water bath, has begun acceptance testing. It should be available as Quokka comes on-line in mid 2007.
