B: The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. Supply voltage is 100 volts between the cath- ode and all other electrodes connected together as anode. C: Red/White ratio is the quotient of the cathode current measured us- ing 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: 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. E: Measured with the same light source as Note B and with the voltage distribution ratio shown in Table 1 below. Table 1: Voltage Distribution Ratio F: Measured with the same supply voltage and voltage distribution ratio as Note E after removal of light. G: 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. ENI = where q = Electronic charge (1.60 × 10 -19 coulomb). ldb = Anode dark current(after 30 minutes storage) in am- peres. G = Gain. Δf = Bandwidth of the system in hertz. 1 hertz is used. S = Anode radiant sensitivity in amperes per watt at the wavelength of peak response. H: 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. 2q·ldb·G·Δf S Anode Dark CurrentF (After 30 minutes storage in the darkness) ns ns ns — 55 0 nA Electrode Distribution Ratio K Dy1 Dy2 Dy3 Dy4 Dy5 Dy6 Dy7 Dy8 Dy9 P 1111111111 Supply Voltage=1000Vdc K:Cathode Dy:Dynode P:Anode Unit
