Technical Session 2: HIE-ISOLDE
- Yacine Kadi (CERN)
After the first successful physics run with radioactive ion beams at HIE ISOLDE, in October 2015, the staged deployment of the linac continued in 2016 by adding a second cryomodule and by refurbishing the first one. During the physics run with one cryomodule, the second cryomodule was being assembled. The refurbishment of the first cryomodule was made necessary to overcome limits imposed by...
The High Intensity and Energy ISOLDE project (HIE-ISOLDE) is a major upgrade of the ISOLDE facility at CERN. The energy range of the post-accelerator will be extended from 2.85 MeV/u to 9.3 MeV/u for beams with A/q = 4.5 (and to 14.3 MeV/u for A/q = 2.5) once all the cryomodules of the superconducting accelerator are in place. The project has been divided into different phases, the first of...
A new design of the Quarter Wave Resonator (QWR) for Cryomodule (CM) 4 will be presented.
Since the performance of the recent QWRs produced seems limited by the welding at the highest radio-frequency (RF) magnetic field, intensive efforts have been made to design a seamless QWR without welding process. A beam port was removed for machining the whole shape of the cavity from a one single bulk...
The REX-ISOLDE post-accelerator comprises 7 RF cavities that are powered by their respective RF systems. Their purpose is the acceleration of radioactive ion beams of a wide spectrum of ion species from 5keV/u to up to 3MeV/u. This talk will provide a short introduction to the RF systems of this accelerator, and it will then focus on their operation and current limitations.
