The H9305-04 is a photomultiplier tube module with a 13-mm side-on photomultiplier and integrated Cockcroft-Walton power supply in an aluminum housing. It uses a multialkali photocathode with UV glass window, optimized for low dark current in the UV to near IR range. It operates from +11.5 to +15.5 V, draws up to 7 mA, and delivers a maximum output current of 10 µA. Control voltage ranges from +0.5 to +1.2 V (1 MΩ input impedance). Peak sensitivity is at 530 nm, with a radiant sensitivity of 70 mA/W at 254 nm. Dark current is 1 nA maximum. Rise time is 1.4 ns, and output ripple is 0.5 mV peak to peak. Operating temperature is +5 to +50 °C. Dimensions are 50.8 mm length with a 4 × M2 mounting base. Signal output uses RG-174/U coaxial cable.
The H9305 series photomultiplier tube modules contain a high-voltage power supply circuit and a 13 mm (1/2") diameter side-on photomultiplier tube in a compact aluminum housing. The 13-mm (1/2") side-on photomultiplier tube has a reflection mode photocathode that delivers high quantum efficiency at wavelengths above 600 nm, an adequate gain of up to 10e(7) and fast time response. High S/N ratio can be obtained even when measuring extremely low level light at high speeds.The H9305 series uses a Cockcroft-Walton circuit with low power consumption. Flexible cables are used for easy installation in equipment.
