摘要
S-DALINAC极化注入器(SPIN)使用砷化镓光电阴极为核结构研究提供脉冲和/或极化电子束。近年来，研制了一种用于原子氢光阴极活化、测试和清洗的测试装置(Photo-CATCH)。这种设置使用了一个倒置的绝缘体几何形状。为了在SPIN上实现反向设计，在Photo-CATCH上进行了测试和优化。我们将介绍Photo-CATCH的现状，SPIn的计划升级(旨在达到200千伏的工作电压)和未来的测量。*由DFG (GRK 2128“AccelencE”)，BMBF (05H15RDRB1)支持的工作，并通过LOEWE中心HIC for FAIR部分由黑森州支持。
Status and Perspectives of the S-DALINAC Polarized-Electron Injector*
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.
