Notes:
A microchannel-plate photomultiplier (MCP-PMT) has been applied to the time-correlated single-photon counting technique. Electrical and timing characteristics were investigated for the two types of MCP-PMT's, nonproximity type (Hamamatsu R1264) and proximity type (R1564), which are different in distance between the photocathode and MCP. In the proximity type, the transit-time spread was found to be 60 ps, i.e., a factor of 4 shorter than that in conventional photomultipliers with a dynode string. It was concluded that both types of MCP-PMT's are fully applicable to the single-photon counting method and that the proximity type MCP-PMT in particular leads to further improvements in the cathode transit-time difference and the wavelength effect of the timing properties. Some examples of experimental results are shown for fluorescence decay curves and picosecond time-resolved spectra.
