Abstract

The invention discloses an automatic control device, method for preparing photomultiplier cathode, and the prepared photoelectric cathode. The automatic preparation of the photomultiplier cathode canbe realized. Monitoring is conducted in the preparation process, and it can be determined whether abnormity occurs or not through the preset method, and the parameter can be adjusted based on the determination result. The invention is advantageous in that labor can be greatly liberated, and the consistency of the obtained photomultiplier is high.

Description

technical field [0001] The invention relates to the field of photomultiplier tubes, in particular to the automatic preparation process of cathodes in photomultiplier tubes. Background technique [0002] Photomultiplier tube is a kind of light detection device, which can be widely used in research fields such as extremely weak light detection, photon detection, chemiluminescence, bioluminescence, etc. It has the characteristics of high detection efficiency and high time resolution. [0003] The most important thing in the preparation of the photomultiplier tube is the preparation of the photocathode. The current preparation of the photocathode is mainly to manually control the current of the alkali source K, Cs, and Sb through the computer, so that they can fully react at a certain temperature and vacuum to form the cathode layer. [0004] The preparation process of the photocathode mainly includes: baking and degassing, bottom potassium evaporation, antimony potassium evapo...
