NOTES
A: Averaged over any interval of 30 seconds maximum.
B: The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. The light input is 10
-3
lumen. Supply voltage is 150 volts
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.
E: The light input is 10
-8
lumens with the same light source as Note B.
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.
Supply Voltage: 1000Vdc, K: Cathode, Dy: Dynode, P: Anode
