A Cost-Efficient PC Based Frame Grabber as Beam Diagnostic Tool in an EPICS Environment

By B. Franksen, R. Bakker, B. Kuner, J. Rahn and H. Rüdiger

Abstract

Analysis of video images is a common way to determine the properties of an electron or synchrotron radiation beam. At BESSY a cost-efficient frame grabber hardware controlled by a Windows PC allows one to perform such an analysis in real-time. Live video images on the PC monitor give operators a direct view of the beam, optionally enhanced by artificial coloring and graphical overlays. The application software has been integrated into the EPICS environment by including a Channel Access (CA) server. Thus the numerical results and the application's control commands are accessible over a network through CA Process Variables. A newly developed C++ class library is used to provide the variables with the usual attributes required by advanced CA clients such as graphical display managers.Comment: Poster Paper for ICALEPCS-2001 (THAP045), LaTeX, 3 pages, revised versio
