PHOTOMULTIPLIER TUBE R7639 : 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 measure- ment, the whole photocathode is illuminated. : Also called transit time jitter. This is the fluctuation in electron transit time between individual pulses in the signal photoelectron mode, and may be defined as the FWHM of the frequency distribution of elec- tron transit times. : Hysteresis is temporary instability in anode current after light and voltage are applied. Hysteresis = (1) Light Hysteresis The tube is operated at 750 volts with an anode current of 1 micro-am- pere for 5 minutes. The light is then removed from the tube for a minute. The tube is then re-illuminated by the previous light level for a minute to measure the variation. (2) Voltage Hysteresis The tube is operated at 300 volts with an anode current of 0.1 micro- ampere for 5 minutes. The light is then removed from the tube and the supply voltage is quickly increased to 800 volts. After a minute, the sup- ply voltage is then reduced to the previous value and the tube is re- illuminated for a minute to measure the variation.

Table 1: Voltage Distribution Ratio : Measured with the same supply voltage and voltage distribution ratio as Note E after removal of light. : ENI is an indication of the photon-limited signal-to-noise ratio. It re- fers to the amount of light in watts to produce a signal-to-noise ratio of unity in the output of a photomultiplier tube.
