Abstract :
In 2002 the dominant experiment at CERN/ISOLDE was REX-ISOLDE. The LINAC delivered beams of radioactive isotopes at energies of 0.3, 2 and 2.2 MeV/u towards the two target stations. Due to the charge state breeder very different mass regions of the nuclear chart could be addressed from Li to Sm. In order to perform Coulomb excitation and particle transfer experiments in the mass region up to A = 150, an energy of the LINAC is required, which is foreseen in two steps. The first step of the upgrade to 3.1 MeV/u will be done by using the MAFF 202.56 MHz IH-cavity. The second step to energies close to 4.2 MeV/u will be a major change of the LINAC structure. The two 7-gap spiral resonators of REX-ISOLDE will be exchanged by a 202 MHz IH-cavity. Design calculations, cavity design and first measurements with the cavity dedicated for the first step of the upgrade will be presented.
