Status of the fluorescent screens and image processing for the APS linac.

摘要

Ten fluorescent screens and cameras determine the relative position and image profile of the beam in both the electron and positron linacs at the Advanced Photon Source (APS). The timing techniques used to capture the beam image allow direct synchronization to the electron gun trigger to minimize timing uncertainties. This paper discusses the design and status of the APS linac fluorescent screen assemblies and imaging system.
