Handy Single Photoelectron Pulse Model Chosen for its similarity to an actual PMT pulse, a triangle pulse 15ns wide at the base by 5mV high across Z, the termination resistance. 0 -5mV 0 10ns 20ns
A Single Photoelectron Model (15ns)(5mV) 2 Where Z is the termination resistance, and G is the PMT gain G = 37.5 pVs / ( Z . 1.602E-19 ) = 37.5 pVs / 43Ω / 1.602E-19 Coulomb = 5.44E6 = 37.5 pVs = Z G (1.602E-19)
