PMT base for 14- and 12-stage, 20-pin photomultipliers
Socket and resistive voltage divider for 14- and 12-stage photomultipliers that produce high-current pulses. The anode signal is intended for timing and single-photon counting and the linear signal from the tenth dynode for energy measurements; internal trimmers adjust the focus and deflection electrodes and the last dynode.
- PMT compatibility
- 14- or 12-stage, 20-pin socket (JEDEC B20-102), including Hamamatsu R1250; Philips XP2020, XP2020Q, XP2040, XP2040Q, XP2041, XP2041Q, XP2212B, XP2230B, XP2233B, XP2262B; EMI 9813K1
