NOTES

A: Averaged over any interval of 30 seconds maximum.

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: Measured with the anode-to-cathode supply voltage and voltage distribution ratio shown in Table 1.

F: 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.

G: The electron transit time is the interval between the arrival of a delta function light pulse at the entrance window of the tube and the time the output pulse

reaches the peak amplitude. In measurement the entire photocathode is illuminated.
