NOTES

S
where q = Electronic charge. (1.60 × 10-19 coulomb)
ldb = Anode dark current(after 30 minute storage) in amperes.
G = Gain.
f = Bandwidth of the system in hertz. (usually 1 hertz)
S = Anode radiant sensitivity in amperes per watt at the wavelength of peak response
ENI =
G:The rise time is the time for 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.
H: 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.
J: Also called transit time jitter. This is the fluctuation in electron transit time
between individual pulses in the signal photoelectron mode, and may be
defined as the FWHM of the frequency distribution of electron transit times.
K: Hysteresis is temporary instability in anode current after light and voltage
are applied.

ANODE
CURRENT
A: Averaged over any interval of 30 seconds maximum.
B: The light source is a tungsten filament lamp operated at a distribution temperature of 2856 K. Supply voltage is 150 V between the cathode and all
other electrodes connected together as anode.
C: Measured with the same light source as Note B and with the anode-tocathode supply voltage and voltage distribution ratio shown in Table 1 below.
D: Measured with the same supply voltage and voltage distribution ratio as
Note E after removal of light.
E: Measured at the plateau voltage.
F: ENI is an indication of the photon-limited signal-to-noise ratio. It refers to
the amount of light in watts to produce a signal-to-noise ratio of unity in the
output of a photomultiplier tube.

(1)Current Hysteresis
The tube is operated at 750 V with an anode current of 1 µA 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 V with an anode current of 0.1 µA for 5 minutes.
The light is then removed from the tube and the supply voltage is quickly
increased to 800 V. 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.
