Some future colliding-beam experiments require charged particle detection technology to provide excellent time resolution (better than 50 ps). Charged particle detector with such time resolution is being developed at the Budker Institute of Nuclear Physics (BINP). Prototypes based on microchannel plates with semitransparent CsI-photocathode manufactured at BINP have been tested with a beam of relativistic electrons. The beam test results and calculations are in good agreement. The prototype manufacturing and testing process are presented. Results of CsI-photocathode quantum efficiency measurement end electron test beam results are described.
