  2. 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

  3. 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)

  4. x 3 x 3 x 2.66

  5. ` The integral under the curve is92 x 1mV x 10ns = 920 pVs 920/37.5 = 24.53 x 3 x 2.66 = 23.9
