Conditioning of the RF Gun at the Photo Injector Testfaciltiy at DESY Zeuthen
A photo injector test facility is being commissioned at DESY Zeuthen. The aim is to develop and operate an optimized photo injector for future free electron lasers and linear accelerators which require extraordinary beam properties. First operation of the rf gun was done in December 2001. In order to get higher gradients in the rf gun than achieved today in similar normal conducting cavities, extensive conditioning work on the rf gun needs to be done. To increase the efficiency and safety aspects of the conditioning work an Automatic Conditioning Program (ACP) is developed. A deeper analysis of the ACP data is enabled by a Data Aquisition system (DAQ). Specific information about diagnostic elements at the rf gun are given and the requirements in order to simplify the conditioning work are outlined. The events which happened during conditioning so far are briefly described.
