Embodiment Construction

[0014] The specific structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0015] figure 1 It is a schematic diagram of the split pattern principle of the wedge-shaped anode in the position sensitive detector in the prior art. The wedge-shaped anode contains three electrodes: a wedge-shaped anode 1, a strip-shaped anode 2 and a zigzag anode 3.

[0016] figure 2 , image 3 It is a structural schematic diagram of a two-dimensional position-sensitive detector of a double-wedge type particle provided by the present invention. The detector includes a multiplier, a detector bracket and a wedge-shaped anode.

[0017] (1) The multiplier 4 is used to multiply and amplify the signal generated by the incident particles. It is composed of two microchannel plate multiplier V-shaped cascades. The detector must work under vacuum conditions, and the vacuum degree is better than 5× during work. 10 -4 Pa. The working voltage o...

Abstract

The present invention which comprises wedge positive electrode, multiplicator formed by two microchannel board cascaded in V shape and detector support for setting microchannel board multiplicator and wedge positive electrode is featured as setting two half-round wedge positive electrode patterns on an insulation substrate, setting insulation isolating line passed through the centre of circle in between two half-round positive patterns and in between germanium films separately and making insulation isolating lines of two faces alignment and parallel.

Description

technical field [0001] The invention relates to a particle position sensitive detector, which belongs to the technical field of particle detectors. Background technique [0002] The measurement of particle position is an important content of particle detection technology in physics. Realizing particle position measurement through charge distribution is one of the important methods. At present, such detectors include resistive position sensitive detectors and semiconductor type position sensitive detectors. Wedge-type position-sensitive detectors, etc. Resistive and semiconductor two-dimensional position-sensitive detectors have relatively small sensitive detection areas, and require four electrodes to lead out signals, and the cost of subsequent processing circuits is relatively high. The wedge-type two-dimensional position-sensitive detector can have a large sensitive area, low manufacturing cost, low noise, and three-electrode lead-out signals, so the follow-up circuit co...
