Visibly adjusted high-energy ray detector

Abstract

The invention discloses a visibly adjusted high-energy ray detector which comprises a lightproof box body, and a supporting frame, a PMT photoelectric multiplier tube, a horizontal mobile plate and a vertical electric screw rod adjustment frame which are arranged in the lightproof box body, wherein the vertical electric screw rod adjustment frame is arranged on the horizontal mobile plate; a horizontal displacement rod extending out of the back surface of the lightproof box body is arranged at the tail end of the horizontal mobile plate; a horizontal graduated scale parallel to the horizontal displacement rod is arranged on the back surface of the lightproof box body; a vertical displacement rod extending out of the top surface of the lightproof box body is arranged above the vertical electric screw rod adjustment frame; a vertical graduated scale parallel to the vertical displacement rod is arranged on the top surface of the lightproof box body. Due to the mode, the visibly adjusted high-energy ray detector indirectly realizes visible adjustment on the premise of guaranteeing that no light enters the lightproof box body; furthermore, after being adjusted, the visibly adjusted high-energy ray detector is good in fixing effect, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of high-energy ray detectors, in particular to a visually regulated high-energy ray detector. Background technique [0002] When the high-energy ray detector tests the crystal, it needs to move and position the crystal. Due to the sensitivity to light, the test of the crystal is usually carried out in a dark environment. In order to facilitate the adjustment of the horizontal direction of the crystal, it is necessary to set up a horizontal track and a base for carrying. [0003] In the dark environment of the box, the adjustment of the up and down and left and right displacements of the crystal bar rotating carrier cannot be visualized, which brings adjustment difficulties. Moreover, even after the vertical and left and right positions are adjusted and fixed, due to the rotation and vibration of the crystal bar rotating carrier, the The up and down and left and right displacements of the crystal bar rotating carrier ...

[0003] In the dark environment of the box, the adjustment of the up and down and left and right displacements of the crystal bar rotating carrier cannot be visualized, which brings adjustment difficulties. Moreover, even after the vertical and left and right positions are adjusted and fixed, due to the rotation and vibration of the crystal bar rotating carrier, the The up and down and left and right displacements of the rotating carrier plate of the crystal bar have adverse effects, affecting the stability and accuracy of the measurement data
