Description
The EPIC upgrade at ISOLDE will bring with it a whole new range of opportunities for physics with post-accelerated beams. The advantage for HIE-ISOLDE will be two-fold, an increase in the primary yield of the most exotic beams from the 2 GeV upgrade and the reduction in setup time required afforded by freeing the central beam line. This will allow for the maximum use of available beam time; coupled with higher beam intensities delivered to the experimental stations the upgrade will enable measurements of the weakest cross-section reactions or isotopes further from stability. Furthermore, some species with large isobaric contamination or low ionisation/extraction efficiency will be in reach due to the complementary upgrades of the ISOLDE front ends.
Currently, calibrations and detector commissioning using stable, noble gas beams from the residual gas of REX-TRAP are routinely performed at all three of HIE-ISOLDE's experimental stations. The addition of a dedicated ion source or independent feeding of the linac from one of the new target stations could also bring opportunities for physics with stable or long-lived isotopes. This takes advantage of HIE-ISOLDE's unique capabilities in delivering low-intensity beams at energies around the Coulomb barrier across the entire mass range, thanks to the electron beam ion source (EBIS) and state of the art diagnostics.
This talk will describe the different HIE-ISOLDE experimental stations and selected physics cases from each. New opportunities will be highlighted and discussed in terms of the physics impact and current experimental limitations.
