Problems solved by technology

[0003] At present, the technical solutions adopted by photomultiplier tubes, especially small-sized photomultiplier tubes, are mostly dynode type. The structure of the whole tube is complex, and the time characteristic is relatively weak. Parameters such as rise time can be further improved, but it is difficult to obtain better rise time parameters due to various technical conditions, especially the size limit of the anode

Abstract

The invention belongs to the technical field of photomultipliers, and discloses a photomultiplier special-shaped anode with a rapid rise time characteristic, and a photomultiplier. The photomultiplierspecial-shaped anode comprise a ceramic bottom plate and conical metal anodes, wherein the ceramic bottom plate is used as a support, grooves for inserting the conical metal anodes are formed in thesurface of the top of the ceramic bottom plate, the multiple grooves are periodically arranged, the conical metal anode is of a transition gradual change structure with a rectangular top surface and acircular bottom end and is inserted into the groove, the bottom of the conical metal anode extends out of the bottom surface of the ceramic bottom plate, a metal film coating is attached to the surface of the transition gradual change part of the conical metal anode, and the contact area of the ceramic bottom plate and the transition gradual change part of the conical metal anode is metalized andsealed. Due to the adoption of the photomultiplier special-shaped anode, the rising time performance of the photomultiplier can be improved, and the photomultiplier special-shaped anode has good anode uniformity.

Description

technical field [0001] The invention relates to the technical field of photomultiplier tubes, in particular to a special-shaped anode of a photomultiplier tube and a photomultiplier tube with fast rise time characteristics. Background technique [0002] A photomultiplier tube is a light detector that converts a weak light signal into an electrical signal for output. From the category of multipliers, it can be divided into Dynapolar photomultiplier tubes and micro-channel plate photomultiplier tubes. Various types of photomultiplier tubes are widely used in basic physics research, high-energy gamma ray detection, ground cosmic ray telescope observation, double beta decay experiment, proton decay experiment, dark matter detection, neutrino detection experiment and other fields. [0003] At present, the technical solutions adopted by photomultiplier tubes, especially small-sized photomultiplier tubes, are mostly dynode type. The structure of the whole tube is complex, and the ...
