Towards the PUMA pion tracker — •Sabrina Zacarias1, Emanuel Pollacco2, Christina Xanthopoulou1, Alexandre Obertelli1, and PUMA collaboration1 — 1TU-Darmstadt — 2CEA-IRFU
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.
