A 30 ps timing resolution for single photons with multi-pixel Burle MCP-PMT

We have achieved ∼30 ps single-photoelectron and ∼9.1 ps for multi-photoelectron timing resolution with a new 64-pixel Burle MCP-PMT with 10 μm microchannel holes. We have also demonstrated that this detector works in a magnetic field of 15 kG, and achieved a single-photoelectron timing resolution of better than 60 ps The study is relevant for a new focusing DIRC RICH detector for particle identification at future colliders such as the super B-factory or ILC, and for future TOF techniques. This study shows that a highly pixilated MCP-PMT can deliver excellent timing resolution.
