CERN's ISOLDE, an acronym for Isotope Separator
On Line, went into operation again in
1992, after a major upgrading that has placed the
facility in a new building complex fed by a 1 GeV proton
beam from the injector synchrotron, called the PS
Booster. Hence, ISOLDE is now firmly
integrated into the
accelerator architecture of CERN.
originally proposed at the 600 MeV
Proton Synchro-Cyclotron in
1964. The first experiments started there in 1967.
ISOLDE underwent several upgrades until it was finally
moved to the PSB in 1992. Amongst the existing
facilities, ISOLDE presently offers worldwide a wide
diversity of radioactive isotopes, and the installation
of a post-accelerator at ISOLDE (REX-ISOLDE) has opened
new fields of research with radioactive ion beams of
higher energies. In this respect the facility is
complementary to other European radioactive ion beam
accelerators such as SPIRAL (GANIL, France) and GSI (Darmstadt, Germany), and provides a wider range of intense
accelerated ions compared to HRIBF (Oak
USA) and ISAC (Vancouver, Canada).
radioactive nuclides are produced via spallation, fission, or
fragmentation reactions in a thick target, irradiated
with a proton beam from the PSB at an energy of 1.4
GeV and an intensity up to 2
ISOLDE itself is a multidisciplinary
activity but users further benefit from free interplay
of scientific and technological transfer between the
infrastructure and the rest of CERN.
