Experimental Apparatus
There are presently two experimental apparatus to be used for materials studies in CAMS. One is based at the APBF, at the Australian National University node of the Centre. A positron beamline is dedicated to materials studies, allowing the energy of the positrons injected into the sample to be tuned up to 10 keV. This will allow the samples to be probed as a function of depth, up to approximately 1 micron. PALS and 2-D Doppler measurements will be possible with this apparatus.
A second apparatus has been constructed at the University of Western Australia node for the investigation of surface effects. This is a UHV apparatus and includes many tools for the preliminary characterisation of the surfaces to be studied. Positrons, electrons and positronium reemitted from the surface provide tools for the studies of different samples.
