HK 51.28: Poster
Donnerstag, 2. April 2020, 16:30–18:30, Zelt
Towards the PUMA pion tracker — •Sabrina Zacarias for the PUMA collaboration — Institut für Kernphysik, TU Darmstadt
The PUMA project (antiProton Unstable Matter Annihilation) aims at using low energy antiprotons to probe the tail of the radial density of short-lived nuclei. With PUMA, the ratio of proton and neutron annihilations after capture will be determined, giving access to a new observable to quantify the ratio of proton to neutron densities at the nuclear periphery. To accomplish it, PUMA aims at transporting one billion low-energy antiprotons (produced at CERN/ELENA) to the CERN/ISOLDE facility where short-lived nuclei are produced. In the poster, the detection system (consisting of a time projection chamber and a trigger barrel) and the readout electronics development will be detailed.
