在超导130 MeV达姆施塔特电子直线加速器S-DALINAC中，新的极化电子源使用脉冲Ti：Sapphire和二极管激光照射的GaAs阴极。电子源已经在一个带有束线的测试台上安装和调试，其中用于自旋操纵的W ienfilter，用于偏振测量的Mott偏振计和斩波器预聚束系统是系统的一部分。试验完成后，试验台和束线被拆除，并重新安装在S-DALINAC。新的光注入器开辟了潜在的实验与极化电子和光子束的核结构研究在低动量转移。将在所有实验地点安装各种偏振计，以监测光束偏振。我们报告的S-DALINAC，从测试台性能的结果，偏振源和偏振仪的研究和发展的实施。
At the superconducting 130 MeV Darmstadt electron linac S-DALINAC the new source of polarized electrons uses a GaAs cathode illuminated with pulsed Ti:Sapphire and diode laser light. The electron source had been set up and commissioned at a test stand with a beam line where aW ienfilter for spin manipulation, a Mott polarimeter for polarization measurement and a chopper-prebuncher system were part of the system. Upon completion of the tests, test stand and beam line were dismantled and re-installed at the S-DALINAC. The new photo injector opens up the potential for experiments with polarized electron and photon beams for nuclear structure studies at low momentum transfers. Various polarimeters will be installed at all experimental sites to monitor the beam polarization. We report on the S-DALINAC, the results from the teststand performance, the implementation of the polarized source and the polarimeter research and development.
