Automatic Tracking Of Laser And Electron Beam Intersection

Le résumé fourni par la source

For the Compton Polarimeter experiment at the Stanford Linear Accelerator the crossin point of a laser beam across the path ob an electron beam must be kept accurate and stable. An electronic system is described for automatic tracking and correction of the beam crossing. A remote CCD camera, relatively insensitive to electromagnetic disturbance, records small displacements of the pulsed laser beam. Video signals are anal zed at a remote station, the amount of drift from the selectedreference point determined and the appropriate correction command sent to the motorizedmirror deflectingthe laser beam. A description of the system, its performance and the test results are presented.
