Motivation of
REX-ISOLDE
Through the advent of post-accelerated
beams with REX-ISOLDE at CERN, probing nuclear properties using transfer
reactions and Coulomb excitation of exotic nuclear species is now possible.
REX-ISOLDE currently provides beams of energies 0.28-0.32 MeV/u, 1.2-2.2 MeV/u
and 2.2-3 MeV/u into the gamma-ray MINIBALL array, and other instrumentation
setups at the secondary target position. REX-ISOLDE currently provides accelerated beams to
two secondary target positions, including the HPGe gamma spectrometer, which in its present phase of operation
has a full-energy peak efficiency of approximately 10% for a photon energy of 1 MeV.
Scheduled energy and intensity up-grades
will increase the physics potential of ISOLDE even further. The energy upgrade
can be considered in two phases: (1) to increase the energy to 5.5 MeV/u by
2011 that enables certain classes of nuclear reactions to be used on a wide
range of nuclei and (2) further increase the energy to at least 10 MeV/u that
will enable all reactions to be employed for all nuclei. See HIE-ISOLDE
linac homepage for further information. The ISOLDE hall has been extended in
order to house the additional linac cavity resonators and other instrumentation
such as new recoil spectrometers for detection of fusion products.
Below one finds links to a few of the
on-going experiments at REX-ISOLDE.
