(at –20 ) Hamamatsu R3310-02 and R4330-02 are 51mm (2") diameter head-on type photomultiplier tubes having InGaAs (Cs) photocathodes, and linear focused CuBeO dynodes. The InGaAs (Cs) photocathode allows high sensitivity over a wide spectral range up to 1040nm. The R3310-02 and the R4330-02 are selected for photon counting, and they feature low dark counts and excellent pulse height distribution (PHD) of single photoelectrons.

B Measured at single photoelectron level. The discriminator level is set at valley point. C In practical operation, the cathode current should be lower than 2pA to pre- vent shortening the life of the photocathode. D For cooling operation, another ceramic socket, type number E678-21D is rec- E F G H J K ommended, because the teflon socket type number E678-21C supplied with the tube is not suitable for cooling operation due to its high thermal expansion coefficient. Alternatively, it is recommended to solder a resistor, capacitor, etc. directly on stem pins using a socket contact (100-2520S) supplied by Winchester. Supply voltage is 150 volts between the cathode and all other electrodes. The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. The quotient of the cathode sensitivity measured with the light source is the same as Note E passing through a red filter (Toshiba R-68) divided by the cathode luminous sensitivity without the red filter. Measured with supply voltage and voltage distribution ratio in Table 1. Measured with supply voltage to provide the anode luminous sensitivity of 40 (A/lm) and the voltage distribution ratio in Table 1 after 30 minutes storage in the darkness. Measured with supply voltage that gives 2 106 gain and with the voltage distri- bution ratio shown in Table 1 after one hour storage in the cooler set at –20 . The discriminator is set at 1/3 of a single photoelectron level. L The rise time is the time it takes the output pulse to rise from 10% to 90% of the peak amplitude when the entire photocathode is illuminated by a delta function light pulse. M The electron transit time is the interval between the arrival of a delta function light pulse at the entrance window of the tube and the time when the output pulse reaches the peak amplitude. In measurement the entire photocathode is illuminated. Warning–Personal Safety Hazards Electrical Shock Operating voltages applied to this device present a shock hazard.

Therefore, when performing photon counting, it is recommended that the tube be cooled down to about –20 . The cooler C2761 which features temperature control from –30 to 0 is available from HAMAMATSU.
