FEATURES
The H11432 series is a current-output type photomultiplier tube assembly that contains a 38 mm (1-1/2") diameter head-on PMT and a high voltage power supply. Incident light is efficiently collected by a large photosensi- tive area, making the H11432 ideal for scintillation counting. Parameter H11432 H11432-100 Unit Spectral Response Input Voltage Max.
