Description
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. 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 talk, an overview of the project and its current status will be given. In particular, the foreseen concept for extreme high vacuum for antiproton storage and the analysis method to determine the proton to neutron annihilation ratio will be detailed.
