Stability Simulations of the p Cloud in the PUMA Trap — •Alexander Schmidt, Alexandre Obertelli, Oliver Boine-Frankenheim, and Noritsugu Nakastuka — TU Darmstadt, Darmstadt, Germany
The PUMA (antiProton Unstable Matter Annihilation) project aims at the investigation of the nucleon density tails of short-lived nuclei by the means of nucleon-antiproton annihilations. These antiprotons will be trapped in a Penning trap at the ELENA facility of CERN and afterwards transported to ISOLDE for measurements. Due to the small amount of exotic nuclei with large neutron or proton excess that can be produced at ISOLDE, as many p as possible need to trapped to get sufficient statistics. Such large numbers of antiprotons in the trap volume imply repulsive internal space charge fields which need to be compensated. The present work aims at the simulation of the p cloud in the trap and the behaviour of the plasma during sympathetic cooling by electrons.
