The HIE-ISOLDE Project — •Alexander Herlert — CERN, Physics Department, 1211 Geneva 23

Forty years after ISOLDE started operation at CERN in 1967 it is still today the leading ISOL facility in terms of the variety of extracted radioactive beams. An increasingly important component during the last years has been the REX-ISOLDE post-accelerator that presently can accelerate most ion beams produced at ISOLDE up to a maximum energy of 3 MeV/u. The HIE-ISOLDE project [1] includes several important upgrades of the present facility: The existing normal-conducting post-accelerator will be extended using superconducting technology with an intermediate step with acceleration to 5.5 MeV/u and the final objective being to provide radioactive beams up to 10 MeV/u. The beam quality will be improved in several respects: through the installation of an RFQ cooler, a new resonant laser ionization system, and a renovated High Resolution Mass Separator. Combined with the continuing target and ion source developments this will provide significant improvements for experiments and give a total of more than 1000 different ISOL beams for experiments. Finally, the driver beam intensity will be increased, at first due to a faster cycling of the PS Booster accelerator, at a later stage due to the new injector accelerator Linac-4. The target design will be adapted to accommodate this higher intensity. The presentation will focus on the technical improvements and give an overview of the present stage of the project, but will also present selected examples of the physics possibilities.
