Photomultiplier tube module


The H11526 series is a photomultiplier tube module that allows gate operation. The combination of built-in metal package PMT and gate circuit makes this module compact yet still provides excellent characteristics: 100 ns minimum gate width, 10 kHz repetition rate. This module also contains a high-voltage power supply so that PMT gain can be varied by simply adjusting the control voltage. The internal protection monitor issues an error signal if high-intensity light enters the module.

There are two types of gate operation and they has own Type Numbers.
H11526-20-NN : Normally ON
H11526-20-NF : Normally OFF
Please see PDF catalog about the gate operation details.
