Thermoelectric Coolers
Thermoelectric Coolers C659 Series
The C659 series is a thermoelectric cooler designed to reduce photomultipli-
er tube dark current and to enhance the photomultiplier tube lower detection
limit. When used with a photomultiplier tube having an Ag-O-Cs photoca-
thode in DC mode, the dark current can be reduced to 1/200 of its normal
level at room temperature.
In cooling a photomultiplier tube one sometimes encounters problems such
as dewing on the incident window and leakage current on the socket or base
of the tube. But these problems are eliminated by use of an evacuated, dou-
ble pane window and custom socket assembly.
The C659-50 series is designed for 38 mm (1-1/2") and 28 mm (1-1/8") di-
ameter head-on photomultiplier tubes. The C659-70 series is specifically in-
tended for use with 28 mm (1-1/8") diameter side-on photomultiplier tubes.
