The aim of the HIE-ISOLDE project is to greatly expand
the physics programme compared to that of REX-ISOLDE.
HIE-ISOLDE forms part of the European nuclear physics
strategy, and its science case covers the majority of
the key questions in nuclear structure and astrophysics
pursued by our community.
The HIE-ISOLDE project contains three major elements: higher
energies, improvements in beam quality and flexibility, and
higher beam intensities. This requires developments in
radioisotope selection, improvements in charge-breeding and
target-ion source development, as well as construction of the
new injector for the PS Booster, LINAC4. The most significant
improvement will come from replacing most of the existing REX
accelerating structure by a superconducting (SC) linear
accelerator with a maximum energy of 10MeV/u.
This would allow all ISOLDE beams to be accelerated to energies
well below and significantly above the Coulomb barrier,
facilitating a broad programme of nuclear structure and nuclear
astrophysics studies using different classes of nuclear
