Abstract

The invention discloses a negative electrode transfer equipment-based indium sealing method of a photomultiplier. After fabrication of a negative electrode, the sequence of an air absorption agent toremoval gas, simulation time, a switch multi-chip packaging (MCP) baffle plate and a lifting MCP pipe core is reasonably arranged, so that the indium sealing process has definite operation standard, favorable vacuum degree is obtained, and the performance of the photomultiplier is improved.

Description

technical field [0001] The invention relates to the field of photomultiplier tubes, in particular to an indium sealing method involved in the preparation process of photomultiplier tubes. Background technique [0002] The photomultiplier tube is a photosensitive element with many uses. In the application of detecting radiant energy in the electromagnetic spectrum in the ultraviolet, visible and infrared ranges, the photomultiplier tube is currently the most sensitive detector. With the improvement of the function of the photomultiplier tube, it has more and more applications in many aspects such as optical physics, industrial control and space exploration. [0003] The photomultiplier tube, as a highly sensitive detector, is able to work with such weak signals as a single photoelectron pulse from the cathode. That is, the count of output pulses in a given time interval provides a measure of the rate at which light strikes the photocathode. [0004] The patent with the appl...
