S MODERN phototube circuit will permit you to turn your lights or other electrical
appliances on or off by either shining a light beam onto the phototube, or
breaking a light beam that is shining on the tube. It has many applications, such
as ...

ADVANCES ELECTRONIC &ELECTRON PHYSICS
In order to obtain an estimate of the thermionic dark current of a bluesensitive
phototube, it is instructive to consider a 1P21 multiplier phototube employed as a
simple vacuum phototube. The maximum cathode dark current of a 1P21 is about
...

the second course of light
Light from a source S passed through an electro-optic shutter and was reflected
at a mirror M into a phototube. A phototube consists of a cathode of a suitable
material, which emits electrons when light falls upon it, and a metal anode to
attract ...
During the transfer from the scintillator to the photocathode, light may be lost by
leaving through the sides and front face of the scintillator, or by being reflected
back to the scintillator when it hits the window of the phototube. To avoid loss of ...

Radiometry and Photometry
Introduction In the past, measurements of the effective intensity of condenser-
discharge lights have generally been made by two methods: (1) coupling the
output of a phototube to a cathode-ray oscilloscope, photographing the trace of
the ...

Organic Scintillators and Scintillation Counting
B. H. Laney Nuclear-Chicago Corporation Des Plaines, Illinois ABSTRACT
Approximately 33% of the total background count rate of a conventional liquid
scintillation counter is caused by optical crosstalk between the phototube
detectors.
The rectifier tube controls the high voltage to the phototube, and the amplifier
tube provides the current to the sensitive relay. The sensitive relay is in the lower
beam position when the amplifier tube current is off. The rectifier tube is adjusted
to ...
