The primary target for the hypernuclear experiment at PANDA — Sebastian Bleser1, Felice Iazzi2, •Marta Martinez Rojo1, Josef Pochodzalla1,3, Nicolas Rausch3, Alicia Sanchez Lorente1, and Marcell Steinen1 for the PANDA collaboration — 1Helmholtz-Inst. Mainz — 2Politec. and INFN, Torino — 3Inst. für Kernphysik, JGU Mainz
A key aspect of the PANDA experiment at the future FAIR facility is the production and spectroscopy of ΛΛ hypernuclei. The double hypernuclei are produced in a two-stage target system consisting of a primary in-beam filament to produce low momentum Ξ− hyperons which are stopped and converted into two Λ hyperons in a secondary external target.
A system of piezo motors will be used to steer the primary target in two dimensions. This allows to achieve a constant luminosity by adjusting the position and provides the replacement of eventually broken target wires.
The poster shows the mechanical integration of this system within the vacuum chamber attached to the beampipe. Its motion is controlled using the EPICS framework as planned for PANDA. In addition the results of radiation tests with foreseen target wires will be presented.
