Cherenkov counter for bunch intensity measurements in slow extracted beams from the IHEP accelerator is described. The dynamic range is from 1 to 106 particles/bunch and bunch frequency is up to 6x106/s. Cherenkov light is detected by XP 2020 PMT. XP 2020 signal pulse height and delay were measured as a function of XP 2020 high voltage from 0.8 to 2.7 kV using green and blue LED’s. Results of the counter calibration in the 50 GeV proton beam are presented. The model used to fit the counter height pulse spectra is discussed.
