Averaged over any interval of 30 seconds

The light source is a tungsten filament lamp
operated at a distribution temperature of 2856K.
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(Coming 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.
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.
Measured with the same light source as Note B
and with the voltage distribution ratio shown in
Table 1 below.

Measured with the same supply voltage and
voltage distribution ratio as Note E after removal of
light.
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.
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.
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
Hysteresis is temporary instability in anode current
after light and voltage are applied.
(1)Current Hysteresis
The tube is operated at 750 volts with an anode
current of 1 microampere 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.
