Positron Facilities

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).
  • 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.
  •  22Na based conventional Positron Annihilation Life time Spectrometer (time resolution 250 ps).
