“…The extraction field at the cathode is very weak and consequently photoelectrons produced by blue light (hc/ λ~ 3 eV) do not focus on to d 1 in the same way as do photoelectrons with less initial energy. Moszynski and Vacher (1977), have shown that the transit time dispersion is wavelength dependent, thereby supporting the aforementioned. The situation is further complicated by the fact that the inner surface of the window, the inner wall of the glass envelope between the window and d 1 and the first dynode itself are all photosensitive.…”

technical reprint R/P076 abstract Two means for measuring multiplier gain are described. The determination of the total number of single electron pulse, N enters into both methods. Use of a multichannel analyser of calibrated input sensitivity reveals that the error in determining arises mainly from an inability to assess whether all contributions from the low energy region of the pulse height distribution have been included in N. It is concluded that mean gain measurements with better than 10% accuracy are unlikely for most photomultipliers. This has serious implications for the absolute measurement of light intensities through the need to know F, the collection efficiency, the determination of which can be sensitive to the assumed values of and var .

“…This increases the number of photoelectrons and improves the time resolution. However, a cut-off of the PC sensitivity at longer wavelengths affects the time jitter because of a larger initial velocity of released photoelectrons [9].…”

“…The venetian blind structure, although effective as an electron multiplier, introduces an uncertainty in the time and pulse height response of the PM. This uncertainty is about 2 ns in time and 10-30% in pulse height for single photon interactions [8]. Measurements show that PM time jitter at one pe illumination is asymmetrically distributed with a fwhm of 10-11 ns (4-5 ns standard deviation about the peak with a tail extending out to 40 ns beyond the peak).…”
