Abstract
The S-DALINAC Polarized Injector (SPIN) uses GaAs photocathodes to provide pulsed and/or polarized electron beams for nuclear-structure investigations. Recently, a test facility for Photo-Cathode Activation, Test, and Cleaning using atomic-Hydrogen (Photo-CATCH) has been developed. This setup uses an inverted insulator geometry. Tests and optimizations are conducted at Photo-CATCH in order to implement the inverted design at SPIN. We will present the current status of Photo-CATCH, the planned upgrade of SPIn (aimed at an operational voltage of 200 kV) and future measurements.
*Work supported by DFG (GRK 2128 “AccelencE”), BMBF (05H15RDRB1), and in part by the state of Hesse through the LOEWE center HIC for FAIR.
