  • new developments

  • fast read-out

  • lower noise level

  • shorter T1/2

  • lower electron energies

  • - new probes (65Ni, 61Co, 27Mg, 8Li,)

  • lattice location in semiconductors

  • related to ferromagnetism

NuPECC 22-23 June 2007


Rex post accelerator
REX post-accelerator

  • Originally constructed by several CERN member states

    ~ 15 MCHF

  • Utilises now  50% ISOLDE running time

  • REX has accelerated 43 different RIB

  • Present RIB yield from ISOLDE allows 10% of all 700 radioisotopes be used
