| Popis: | A technique is described for in-situ calibration of the beam-spill control system at LAMPF. Radiation produced by intercepted beam at the wire scanners is employed as a test source. It is shown that the secondary emission current from the wire scanner is a useful measure of the intercepted beam. The wire scanners are inserted into the beam by a digital-data servo system until the desired level of radiation is produced. Interesting digital-data servo-loop responses are displayed. The entire calibration procedure is programmed by the accelerator control computer and can be repeated as often as required without turning off the beam. The calibration programs have been written so that the conditions of the detectors and signal cables are determined and recorded. |
