Time response of various types of photomultipliers and its wavelength dependence in time‐correlated single‐photon counting with an ultimate resolution of 47 ps FWHM

The time response of the classical photomultipliers 56DUVP and XP2020 in time‐correlated single‐photon counting has been measured at several wavelengths between 257 and 630 nm with a best result of 235 ps FWHM. Also, the time response has been measured of the microchannel‐plate photomultiplier R1564...

Zusammenfassung:	The time response of the classical photomultipliers 56DUVP and XP2020 in time‐correlated single‐photon counting has been measured at several wavelengths between 257 and 630 nm with a best result of 235 ps FWHM. Also, the time response has been measured of the microchannel‐plate photomultiplier R1564U‐01 and the crossed‐field photomultiplier VPM‐154M at the two wavelengths 273 and 546 nm. The best result was 47 ps at λ=273 nm. The use of a fast constant‐fraction discriminator was crucial. The origin of after pulses in the time response curve of photomultipliers is discussed.
