WebMatrix type multianode photomultiplier tubes have excel-lent immunity to magnetic fields. This is because all parts except the photocathode are housed in a metal package and also because the distance between dynode electrodes is very short. Magnetic characteristics of a 64-channel multianode photomultiplier tube are explained below. WebPMT is an analytical device used for light detection. PMT detects the light signals of very low strength. PMT is very accurate and light sensitive, and it ha...
