Resistive board chamber detector

Abstract

The invention discloses a resistive board chamber detector which comprises a first circuit board, a second circuit board, a first glass piece, a second glass piece, a first graphitic layer, a second graphitic layer, a third glass piece and an annular sealing strip. The first circuit board and the first circuit board are arranged in a spaced mode, the sealing strip is connected between the first circuit board and the second circuit board, a sealing cavity is defined by the sealing strip, the first circuit board and the second circuit board together, an air inlet and an air outlet are formed in the sealing strip in a spaced mode, and both communicated with the sealing cavity, and the first glass piece, the second glass piece and the third glass piece are all located in the sealing cavity. The resistive board chamber detector is a self-sealed multi-air-gap resistive board chamber detector, has the self-sealing performance, does not need to be placed in a flow air box and can independently work, therefore, the cost for manufacturing the flow air box is omitted, and ventilation time and air exchange time spent in preparation before an experiment are shortened.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation detection, in particular to a resistive plate chamber detector. Background technique [0002] Multi-gap Resistive Plate Chamber (MRPC) is a new type of gas detector that has developed rapidly in the past ten years. Because of its good time resolution, high detection efficiency, low cost, and easy The advantages of area manufacturing and not being easily affected by magnetic fields are widely used in the construction of large-scale time-of-flight detection systems in high-energy physics and nuclear physics experiments. The MRPC in the related art is open and requires a metal flow box to provide a closed space for gas flow. However, making a metal flow box not only increases the production cost of the detector, but also the large volume of the flow box also means that a longer The ventilation time is used to prepare for the experiment. At the same time, due to the large volume of the conf...

The MRPC in the related art is open and requires a metal flow box to provide a closed space for gas flow. However, making a metal flow box not only increases the production cost of the detector, but also the large volume of the flow box also means that a longer Ventilation time is used to prepare for the experiment. At the same time, due to the large volume of the confined space and the problem of low gas exchange efficiency, the performance of the detector is reduced.
