Echidna and Wombat
Echidna (high-resolution powder diffractometer) and Wombat (high-intensity powder diffractometer)
A new gas-dosing equipment was tested on Echidna.
Sam Duyker (Univ. Sydney) and Vanessa Peterson (Bragg Institute) assemble the equipment for testing.
The system is delivering an accurate dose of gas or gas mixtures to samples for neutron-scattering experiments, using a design based on similar equipment at NIST in the USA. In its first use, this equipment will be used to investigate new hydrogen-storage materials, as part of ANSTO?s research project ?Neutrons for the Hydrogen Economy?. This equipment will be initially used at sample temperatures in the range 1.5 ? 700 K on the two powder instruments, Echidna and Wombat, and plans are already in place to run the equipment on several other instruments, notably Taipan and Pelican.
