Measurement of Charge Emission from Targets as a Means of Burst Intensity and Beam Intensity Monitoring

Internal and external operational targets for the CERN Proton Synchrotron have been electrically insulated and the charge emission from the targets measured as a means of burst intensity monitoring. Charge emission from plates placed in ejected beams have been used for beam intensity monitoring. The measurements presented here concern linearity, saturation and reproduceability tests and investigations of the various parameters influencing the signal level. The main contribution to the signal comes from 6-rays which escape from the target. Theoretical results are presented and compared with experimental results.
