Description
The CRYRING array for reaction measurements (CARME) is a charged particle detector array installed at the CRYRING storage ring designed to perform nuclear reaction measurements directly
at stellar energies, and indirect studies of key nuclear properties. Heavy-ion beams are circulated
around the ring and interact with an ultra-thin gas-jet target. The reaction products are detected by
four, highly segmented, double-sided silicon detectors installed directly under XHV vacuum (10-12
mbar) with no pockets or windows. Measurements can be complex as the detectors are required
to move in and out of the beam axis regularly to avoid un-cooled beam when it is first injected
into the ring. In 2022, CARME was successfully commissioned and the experimental procedures
for reaction measurements using this methodology have been developed. This measurement was
the first use of the internal gas target, the first beam on target and the first observation of nuclear
reactions at the CRYRING and acts as a launch pad for the exciting physics programme ahead.
In this talk, I will present the astrophysical motivation and experimental details of several of the
measurements part of this future programme
