PHOTOMULTIPLIER TUBES
R331, R331-05
For Liquid Scintillation Counting
Bialkali Photocathode, 51mm (2 Inch) Diameter, 12 Stages, Head-On Type
The R331 and the R331-05 are 51mm (2 Inch) diameter series pho-
tomultiplier tubes specifically developed for the liquid scintillation count-
ing. They feature low background noise, high tritium efficiency, good
linearity and high gain. The R331 uses a synthetic silica input window
and the R331-05 uses a low K content borosilicate glass input window,
both with a frosted surface and convex-concave shape. They offer min-
imized glass scintillations and high collection efficiency.
FEATURES
Tritium efficiency in tritium window................................ 60% Typ.
Background noise in tritium window...............16cpm Typ. (R331)
18cpm Typ. (R331-05)
Tritium end point (T.E.P.) voltage.................................. 1700V Typ.
Dark pulse summation at T.E.P. voltage.............. 3 × 104cpm Max.
Figure of merit (E2/B).......................................................... 200 Typ.

interposed between the light source and the tube under
the same condition as Note B.
CHARACTERISTICS (at 25°C)

of the tube and the time when the output pulse reaches
the peak amplitude. In measurement the entire
