pF
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
100 V between the cathode and all other electrodes
connected together as anode.
C: Red/White ratio is the quotient of the cathode current
measured using a red filter (Toshiba R-68) interposed
between the light source and the tube by the cathode
current measured with the filter removed under the
same conditions as Note B.
D: The value is cathode output current when a blue filter
(Corning CS 5-58 polished to 1/2 stock thickness) is
interposed between the light source and the tube under
the same condition as Note B.
E: Measured with the same light source as Note B and with
the voltage distribution ratio shown in Table 1 below.

F: Measured with the same supply voltage and voltage
distribution ratio as Note E after removal of light.
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 amplitube. In measurement, the whole
photocathode is illuminated.
I : Also called transit time jitter. This is the
fluctuation in electron transit time

(1)Light 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.
