NOTES
A:
The light source is a tungsten filament lamp operated at a distribution temperature of 2856 K. Supply voltage is 100 volts between the cathode and all
other electrodes connected together as anode.
The value is cathode output current when a blue filter(Corning CS 5-58
B:
polished to 1/2 stock thickness) is interposed between the light source and
the tube under the same condition as Note A.
Red/White ratio is the quotient of the cathode current measured using a red
C:
filter (Toshiba R-68) interposed between the light source and the tube the
cathode current measured with the filter removed under the same condition
as Note A.
Measured with the same light source as Note A and with the anode-to-
D:
cathode supply voltage and voltage distribution ratio shown in Table 1 below.
Measured with the same supply voltage and voltage distribution ratio as
E:
Note D after removal of light.
ENI is an indication of the photon-limited signal-to-noise ratio. It refers to
F:
the amount of light in watts to produce a signal-to-noise ratio of unity in the
output of a photomultiplier tube.

ldb = Anode dark current (after 30 minute storage) in amperes.
G = Gain.
∆f = Bandwidth of the system in hertz. 1 hertz is used.
S = Anode radiant sensitivity in amperes per watt at the wave length of peak response.
The rise time is the time for the output pulse to rise from 10 % to 90 % of

coulomb).
H:J:The electron transit time is the interval between the arrival of delta function
light pulse at the entrance window of the tube and the time when the anode
output reaches the peak amplitude. In measurement, the whole photocathode is illuminated.
Hysteresis is temporary instability in anode current after light and voltage
are applied.

ANODE
CURRENT
(1)Current Hysteresis
The tube is operated at 750 volts with an anode current of 1 micro-ampere for
5 minutes. The light is then removed from the tube for a minute. The tube is
then re-illuminated by the previous light level for a minute to measure the
variation.
(2)Voltage Hysteresis
The tube is operated at 300 volts with an anode current of 0.1 micro-ampere
for 5 minutes. The light is then removed from the tube and the supply voltage
is quickly increased to 800 volts. After a minute, the supply voltage is then
reduced to the previous value and the tube is re-illuminated for a minute to
measure the variation.
