The light source is a tungsten filament lamp operated at a distribution tem- perature of 2856K. Supply voltage is 100 volts between the cathode and all other electrodes connected together as anode. 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. The value is cathode output current when a blue filter(Corning CS-5-58 polished to 1/2 stock thickness) is interposed between the light source and the tube under the same condition as Note B. Measured with the same light source as Note B and with the voltage distri- bution ratio shown in Table 1 below. 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 refers to the amount of light in watts to produce a signal-to-noise ratio of unity in the output of a photomultiplier tube. where q = Electronic charge (1.60 10 -19 coulomb). ldb = Anode dark current(after 30 minutes storage) in amperes. G = Gain. f = Bandwidth of the system in hertz. 1 hertz is used. S = Anode radiant sensitivity in amperes per watt at the wave- length of peak response. 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.
