NOTES

1. Averaged over any interval of 30 seconds maximum.

2. Supply voltage of 1000 volts is applied between the cathode

and the anode using the voltage distribution ratio shown

below.

3. The light source is a tungsten filament lamp operated at a

distribution temperature of 2856K. The light input is 0.01

microlumen.

4. Under the same conditions as Note 3 except that the light

input is 0.01 lumen and 100 volts are applied between the

cathode and all other electrodes connected together as an

anode.

5. The red/white ratio is the quotiant 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 condition

as Note 4.

6. The rise time is the time for the output pulse to rise from

10% to 90% of the peak amplitude when the entire photo-

cathode is illuminated by a delta function light pulse.

7. Hysteresis is a temporary instability in anode current after

light and voltage are applied.
