The block of cooling of a PMT
The block of cooling of a PMT
It is intended for noise reduction of photomultiply tubes. Its application allows to increase the relation “signal / noise" more than by one order. It is applied for cooling of PMT such as a PMT - 39, 62, 68, 106

Noise level of a photo- electronmultiplier such as a PMT - 62 (supply voltage -1,3 êV):
à) at room temperature; b) at 80Ê;
a)  |
á)  |
As it is visible from oscillograms, the noise level at temperature 80 K is reduced not less than in 20 times.
