The C14761 is a thermoelectric cooler designed for 28mm diameter side-on photomultiplier tubes (PMT). The C14761 improves S/N (signal to noise ratio) of PMT measurement because of reduction of thermal electrons, which are emitted from PMT photocathode, and minimization of external noise by a built-in electrostatic and magnetic shield.
