PUMA: antiProton Unstable Matter Annihilation is a starting project aimed at measuring annihilation of antiprotons with short-lived nuclei. The objective of PUMA is to determine the surface neutron/proton density profile of short-lived nuclei using the annihilation with antiprotons. The experiments will be carried out at CERN. We are developing a transportable device that can store, transport, and annihilate antiprotons with the short-lived nuclei, so that we can bring antiprotons from ELENA to short-lived nuclei produced at ISOLDE. The PUMA will consists of superconducting solenoid, ion traps for the storage and annihilation, and a detection system for the annihilation products. The development status of the PUMA ion trap will be presented.
