Metal package PMT with Cooler Options for H7421 Series TPHOC0040EE G Heatsink with Fan A7423 The temperature of the H7421 outer case rises due to the thermoelectric cooler housed in the case. The A7423 heatsink efficiently radiates away this heat to prevent a temperature rise in the H7421. The A7423 can be easily installed onto the H7421 with four M3 screws. Apply a coat of heat conductive grease onto the joint surface shared by the H7421 and A7423. G Signal Cable E1168-05 This signal cable comes attached to a BNC connector for easily connecting the H7421 to external equipment. G Optical Fiber Adapter (FC Type) A7412 The A7412 is an FC type optical fiber connector that attaches to the light input window of the H7421. The A7412 can easily be secured in place with four M2 screws. G C-Mount Adapter A7413 The A7413 mount adapter is used when a C-mount lens pro- truding 4 mm or more from the flange-back must be installed onto the H7421. G Power Supply Unit with Temperature Control C8137 The C8137 is a power supply unit with a temperature control function. Just connecting to an AC source of 100 V to 240 V generates the output voltages for the thermoelectric cooler and the A7423 fan, needed for operating the H7421. The pho- tomultiplier tube temperature can be maintained to 0 °C by monitoring the thermistor and regulating the output current for the thermoelectric cooler.

By just connecting to 12 V supply, the M9011 provides power necessary to operate the H7421 series. The M9011 also controls the thermoelectric cooler in the H7421 series so that the output and noise can be maintained at constant levels even when the ambient temperature changes. The thermoelectric cooler and PMT operation can be controlled from an external device by connecting it to the I/O connector on the M9011. Parameter Value Max.
