Scintillator is manufactured by Harshaw Chemical, (Type 12A12), and BICRON (Type 3R3), Nal (Tl), 3" diameter 3" thickness. Drift for 1 hour after 10 minutes of initial warming up with 10µA anode current. A 137Cs source and an Nal (Tl) crystal are employed to measure the pulse height. Warming up time is about 1 hour. a) Long term (Mean Gain Deviation) is defined as follows.

b) Short term Scintillator (Nal (Tl) crystal) is 3" diameter 3" thickness. The photomultiplier is first operated at about 10,000 cps. The photopeak counting is then decreased to approximately 1,000 cps by increasing the distance between source and crystal on the tube. 5. Averaged over any interval of 30 seconds maximum. 6. Same as Note 5 and the whole photocathode is illuminated. 7. The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. The light input of 10-7 lumen is used.
WAVELENGTH (nm)
8. The value is anode output current when the blue filter (Corning CS 5-58 polished to 1/2 stock thickness) is interposed between the light source (providing 10-7 lumen) and the tube under the same condition as Note 7. 9. The condition is the same shown in Note 7 except that the value of light input is 10-4 limen and 150 volts are applied between cathode and all other electrodes connected together as anode. 10. These values are cathode output current when the blue filter (Corning CS 5-58 polished to 1/2 stock thickness) is interposed between the light source (providing 10-4 lumen) and the tube under the same condition as Note 9. 11. Measured after 5-second strage in the dark. 12. The rise time is the time for the output pulse to rise from 10% to 90% of the peak output when the tube is illuminated by a flash of light of very short duration. In measurement, the whole photocathode is illuminated. 13. 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 output pulse at the anode terminal reaches peak amplitude. 14. m is the mean value of total counts, i.e.
0.3m
(counts per channel) = (counts per channel) m

Test conditions: Incident light wavelength is 400nm. +1300V. Ambient temperature is 20°C.
