| Abstract: | The Cherenkov counter for measuring the numbers of protons in bunches extracted from the IHEP accelerator using a slow extraction system is described. The measurement range is from 1 to 106 particle/bunch. The maximum bunch frequency is 6 · 106 s–1. Cherenkov light is measured by an XP 2020 photomultiplier. The results of measurements of the XP 2020 signal amplitude on the applied voltage, obtained using semiconductor light sources are presented. The data of counter calibration on the proton beam are discussed. |
