High-rate photomultiplier-base and precise timing calibration

Abstract

Four hodoscopes with 64 channels each have been designed to run in the high intensity muon beam of the SPS (up to 109 muons/s). Despite a transmission at 310 m the double pulse resolution is ≤ 5 ns and a time jitter of about 100 ps is achieved. The synchronisation is done with a sharp laser pulse.
