Abstract :
We have measured the performance, especially the timing properties, of micro-channel plate photo-multiplier tubes (MCP-PMTs) by irradiating with single photons with/without a magnetic field. A time resolution of σ=30–35 ps was obtained for single photons under 1.5 T. With an MCP-PMT, a small time-of-flight counter, by means of Cherenkov light radiation instead of scintillation light has been prepared, and a time resolution σ∼10 ps was attained for a high-energy π-beam by multiple photons.
