LABORATORI NAZIONALI DI LEGNARO
The High Intensity and Energy (HIE) ISOLDE project is a major upgrade of the ISOLDE and REX-ISOLDE facilities at CERN. The Radioactive ion beam EXperiment (REX) at ISOLDE has provided the nuclear physics community with a wide range of post-accelerated radioactive ion beams (RIBs) since 2001 and can currently deliver beams with energies up to 2.8 MeV/u using a normal conducting linear accelerator. The aim of the HIE-ISOLDE project is to greatly expand the physics programme compared to that of REX-ISOLDE. The most significant improvement will come from replacing most of the existing REX accelerating structure with a superconducting linear accelerator composed ultimately of four high energy and two low energy cryo-modules installed in series, and containing superconducting RF quarter-wave resonators and solenoids.. In order to achieve this target energy of 10 MeV/u, 32 superconducting RF cavities and 8 small solenoids will be installed on the REX-ISOLDE beam line and operated at liquid helium temperature. The seminar will present the work done with a special aspect on the cryogenic control system construction and commissioning. Results from the first cold down will be presented.
