Performance of silicon-strip-detectors in direct contact with absorbers for the secondary target at PANDA — •Sebastian Bleser, Patrick Achenbach, Ralph Böhm, Josef Pochodzalla, and Alicia Sanchez-Lorente — Institut für Kernphysik, Johannes Gutenberg-Universität, Mainz
In order to produce and detect double Λ-hypernuclei at the PANDA-detector at GSI, a small secondary sandwich target is foreseen. This will be composed of stacked silicon-strip-detectors and layers of absorber material, 9Be, 10,11B or 12,13C. Ξ−-baryons escaping the primary 12C-target are decelerated and the weak decay products will be identyfied in the secondary target. After assembling a test station, functionality-tests of silicon-strip-detectors in direct contact with absorberlayers have been performed. The results of these test measurements will be described and the consequences for the operation of the secondary target will be discussed.
