WebPhotomultiplier Tubes. In considering the behavior of a photomultiplier tube, a drawing may be helpful. The resistive voltage divider provides potential to each of the electrodes (photocathode, dynodes) except for the anode, which is maintained at virtual common by external circuits. The envelope of the photomultiplier is typically quartz; only ... Web12 de abr. de 2024 · The high-voltage power supply provides 600–1500 V high-voltage power supply for the photomultiplier tube. The DC-DC module is used to design the high-voltage power supply control circuit. Each detector is composed of independent NaI (Tl) crystal, photomultiplier tube (PMT), digital pulse multichannel analyzer and high … 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. how do i put credit on my vodafone
