I have an old Hamamatsu H5783 PMT, and I am trying to figure out whether it is capable of conducting single photon counting. I am unsure as to what the specific specs needed are for single photon counting. I compared this data sheet (http://ugastro.berkeley.edu/ay122_fall12/PMT/schematics/h5773.pdf) with the data sheet of a newer hamamatsu pmt that specifically states its design for single photon counting, Hamamatsu 10720 PMT (https://www.hamamatsu.com/jp/en/product/alpha/P/3003/3044/H10720-110/index.html), but I do not see a significant difference in rise time or really any specs. Any knowledge if the H5783 is compatible, or what the specific minimum specs are required to conduct single photon counting, would be appreciated.
