How a photomultiplier tube works
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. Webphotomultiplier tube, electron multiplier tube that utilizes the multiplication of electrons by secondary emission to measure low light intensities. It is useful in television camera tubes, in astronomy to measure intensity of …
