Abstract
We measured timing properties of 4 different types of micro-channel-plate photo-multiplier tubes (MCP-PMT) by irradiating with single photons with/without a magnetic field (B); resulted time resolutions are sigma=30-35 ps for single photons under B=1.5 T. A small time-of-flight (TOF) counter comprised a thin quartz Cherenkov-radiator and a MCP-PMT has been tested using pi-beam. The time resolution of sigma=10.6 ps has been attained.
