Performance of 6cmx6cm MCP-based picosecond photo-detectors

Microchannel plate (MCP)-based photo-detectors are capable of micron-level spatial imaging and picosecond-level timing resolution, making them a promising candidate for the next generation high-precision photo-detectors. Argonne National Laboratory (ANL) is currently producing 6x6~cm$^2$, cost-effective, thin planar, glass-body, MCP-based photo-detectors at a newly constructed production system. An indium sealing technique was successfully developed for a permanent detector seal and a several photo-detectors have been produced. The performance of the photo-detectors were characterized with a pulsed laser facility, showing a ~60~ps Transit Time Spread (TTS) resolution and \textless 500~$\mu$m spatial resolution. The test setup, data acquisition, data analysis and the experimental results will be presented and discussed.
