Averaged over any interval of 30 seconds maxi-
mum.
The light source is a tungsten filament lamp opera-
ted at a distribution temperature of 2856K. Supply
voltage is 150 volts between the cathode and all
other electrodes connected together as an anode.
The value is cathode output current when a blue
filter (Corning CS No. 5-58 polished to 1/2 stock
thickness) is interposed between the light source
and the tube under the same condition as Note
B
.
Measured with the same light source as Note
B
and with the anode-to-cathode supply voltage and
voltage distribution ratio shown in Table 1.
Measured with the same supply voltage and vol-
tage distribution ratio as Note
D
at 30 minutes af-
ter 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 func-
tion light pulse.
The electron transit time is the interval between
the arrival of a delta function light pulse at the en-
trance window of the tube and the time the output
pulse reaches the peak amplitude. In measure-
ment the entire photocathode is illuminated.
In the case of R2486
