Averaged over any interval of 30 seconds 

maximum.

The light source is a tungsten filament lamp 

operated at a distribution temperature of 2856K. 

Supply voltage is 150 volts between the cathode 

and all other electrodes connected together as 

anode.

Measured with the same light source as Note B 

and with the voltage distribution ratio shown in 

Table 1 below.

Measured at the voltage which gives anode 

luminous sensitivity of 4A/lm.

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 amplitude. In

measurement, the whole photocathode is 

illuminated.
