Developement of a LabVIEW-based surface with innovative controls for the control system of the spin-polarized electron test source Photo-CATCH. — •Heidi Ayse Rösch, Joachim Enders, Martin Espig, Yuliya Fritzsche, and Markus Wagner — TU Darmstadt, Institut für Kernphysik

Operations of the spin-polarized electron source of the S-DALINAC will be supported by a photo-cathode activation, test and cleaning system, Photo-CATCH. Besides cathode-performance studies, this teststand produces spin-polarized electron bunches from a GaAs photo-cathode that are then transported, manipulated, and characterized by devices in a low-energy beam line. To set and monitor the various components of the beamline, a control system was developed, based on the EPICS framework. As interfaces, LabVIEW was used in combination with a gamepad as a controlling device.

Supported in part by DFG (SFB 634) and by the state of Hessen (LOEWE center HIC for FAIR).
