HIE-ISOLDE SC Linac progress and commissioning in 2016
The HIE-ISOLDE project (High Intensity and Energy ISOLDE) reached an important milestone in October 2015 when the first physics run was carried out with radioactive Zn beams at 4 MV/m. This is a first stage in the upgrade of the REX post-accelerator, whereby the energy of the radioactive ion beams w...

| description | The HIE-ISOLDE project (High Intensity and Energy ISOLDE) reached an important milestone in October 2015 when the first physics run was carried out with radioactive Zn beams at 4 MV/m. This is a first stage in the upgrade of the REX post-accelerator, whereby the energy of the radioactive ion beams was increased from 3 to 4.3 MeV per nucleon. The facility will ultimately be equipped with four high-beta cryomodules that will accelerate the beams up to 10 MeV per nucleon for the heaviest isotopes available at ISOLDE. The first cryomodule of the new linac, hosting five superconducting cavities and one solenoid, was commissioned in summer 2015, while the second one was being assembled in clean room. The new high-energy beam transfer lines were installed and commissioned in the same lapse of time. Commissioning with two cryomodules is planned for Summer 2016 to prepare for a physics run at 5.5 MeV/u in the second half of the year. This contribution will focus on the results of the commissioning and operation of the SC linac in 2015. Plans for the second phase of the HIE-ISOLDE project will be highlighted. |

This contribution will focus on the results of the commissioning and operation of the SC linac in 2015. Plans for the second phase of the HIE-ISOLDE project will be highlighted.After the first successful physics run with radioactive ion beams at HIE ISOLDE, in October 2015 [1], 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 thermal instabilities of the fundamental coupler lines. A modified design for the power couplers was developed and implemented on all the cavities, after extensive validation tests in a vertical cryostat. The paper will describe the lessons learnt from the first commissioning campaign, in particular concerning the fundamental power coupler, the solution adopted, and the results of the 2106 commissioning campaign with two cryomodules, which will allow reaching 5.5 MeV/u for all the species available at ISOLDE.CERN-ACC-2017-351oai:inspirehep.net:16332412017 |
