| ABSTRACT: |
The development of the Surko trap has revolutionised
positron physics, in particular for atomic and molecular studies. At
the Australian National University, we have developed a positron trap
and beam based on this concept for application to the study of
material structure. Positron Annihilation Lifetime Spectroscopy has
been used to study open volume defects in a wide range of materials
from polymers to semiconductors to metals. This talk will present an
overview of the operation of the positron materials beamline at the
ANU, along with examples of recent work on selected targets. Plans for
the expansion of the capabilities of the beamline will also be
presented. |
