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 first prototype mounted with vacuum-capable motors. The optical wire-based sensor in development for position control is presented. Motion and position control is managed using the EPICS framework.
