Spectral Response
Hamamatsu R3310-02 and R4330-02 are 51mm (2") diameter head-on type photomultiplier tubes having InGaAs (Cs) photocath-
odes, 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.

Averaged over any interval of 30 seconds maximum.
Measured at single photoelectron level. The discriminator level is set at valley
point.
In practical operation, the cathode current should be lower than 2pA to pre-
vent shortening the life of the photocathode.
For cooling operation, another ceramic socket, type number E678-21D is rec-
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 coef-
ficient. Alternatively, it is recommended to solder a resistor, capacitor, etc. di-
rectly 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 tempera-
ture of 2856K.
The quotient of the cathode sensitivity measured with the light source is the
same as Note 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 10
6
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.
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.
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.

As Figure 6 shows, the dark counts of the R3310-02 and
R4330-02 decreases by cooling the tube. 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.
