高温光电倍增管是一种在高温下仍能正常工作的光电倍增管.一般光电倍增管的最高工作温度不超过60℃,而高温光电倍增管的最高工作温度可达150℃,甚至175℃. 在某些工作场合,要求光电倍增管能承受高温.例如,在石油勘探方面,钻井深度每增加30m,井底温度就升高1℃,3000m深的井温约? High-temperature photomultiplier tube is a kind of photomultiplier tube which can work normally even under high temperature.Generally, the maximum working temperature of photomultiplier tube does not exceed 60 ℃, while the maximum working temperature of high temperature photomultiplier tube can reach 150 ℃ or even 175 ℃. In some workplaces, photomultiplier tubes are required to withstand high temperatures, for example, in the case of petroleum exploration, the bottom hole temperature increases by 1 ° C for every 30 m of drilling depth,
