2. Scintillator is manufactured by Harshaw Chemical, (Type 12A12), and
BICRON (Type 3R3), Nal (Tl), 3" diameter 3" thickness.
3. Drift for 1 hour after 10 minutes of initial warming up with 10µA anode
current.
4. 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.

where P is the mean pulse height averaged over n readings, Pi is the
pulse height at the i-th reading, and n is the total number of readings.
b) Short term
Scintillator (Nal (Tl) crystal) is 3" diameter 3" thickness. The photomul-
tiplier is first operated at about 10,000 cps. The photopeak counting
is then decreased to approximately 1,000 cps by increasing the dis-
tance 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.
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 oth-
er 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 func-
tion light pulse at the entrance window of the tube and the time when the
output pulse at the anode terminal reaches peak amplitude.
