The positron facilities
- The Variable Energy Positron beam facility ( VEP):
a mono-energetic, magnetically guided positron beam (10^5 positrons/s) at user variable energy ranging from 1 to 30 KeV, for depth selective probing of defects and interfaces (depth range typically from 0-2 micrometer).
- The Electrostatic guided positron beam ( EBeam):
a mono-energetic positron beam (10^4 positrons/s) with electrostatic guidance and focussing, and user variable positron energy ranging from 1 to 30 KeV. Currently used for testing the positron microprobe facility.
- POSitrons at the HOR reactor (POSH):
a very intense continuous positron beam (4 x 10^8 positrons/s) magnetically guided to the testfacilities, powered by gamma pair production inside the HOR-reactor.
- Positron annihilation life time spectrometer (time resolution 150 ps).
The positron instruments can all be used with European funding.
