11. PMT Electrical Model and CMIS
2019-10-30 dirk.meier@ideas.no, http://www.ideas.no 11
The type of coupling the PMT to the input stage (CMIS) matters for signal shape and rate capability.
Shown here is AC coupling (R1 and C2) and the implication on the current pulse (A2) and anode voltage (VPMT).
