The HIE-ISOLDE project — •Magdalena Kowalska and ISOLDE Collaboration — CERN, Geneva, Switzerland

The HIE-ISOLDE (High Intensity Energy) Project is a major upgrade of the ISOLDE/CERN facility which will increase the energy, intensity and quality of the delivered radionuclide beams. It comprises the construction of a new superconducting linear accelerator for the energy increase and a Design Study for the intensity and quality improvements. Its science case covers many of the key questions in nuclear structure and astrophysics.

The energy of the post-accelerated beams will be increased from 3 MeV to 10 MeV thanks to a new superconducting linear accelerator made of 6 cryomodules with sputtered acceleration cavities. Transfer and fusion reactions will become accessible for the first time for many exotic nuclear species. Users are expected to design and build new instrumentation to make best use of these beams.

The new LINAC4 injector installed for the LHC combined with the upgraded PSB injector will boost the energy and intensity of the proton beams impinging on the ISOLDE targets. To profit from this for the production of beams and ensure containment of the increased radiation, a redesign of the target area and of the targets will be undertaken. Upgrades to ion sources and magnetic separators will also enhance the quality and purity of the delivered beams.

Here, we give an overview of the project, timeline, and present status, followed by a presentation of the Letters of Intent for experiments.
