Resistive Panel Chamber Detectors

Abstract

The invention discloses a resistive plate chamber detector. The resistive plate chamber detector comprises: a first circuit board, a second circuit board, a first glass part, a second glass part, a first graphite layer, a second graphite layer, a first Three glass parts and a ring-shaped sealing strip, the second circuit board and the first circuit board are spaced apart from each other, the sealing strip is connected between the first circuit board and the second circuit board and is connected to the first circuit board and the second circuit board The circuit boards jointly define a sealed cavity, and the air inlet and the air outlet are formed at intervals on the sealing strip, and both the air inlet and the air outlet communicate with the sealed cavity, wherein the first glass part, the second glass part and the third glass part The glass parts are located in the sealed cavity. The resistive plate chamber detector according to the present invention is a self-sealing type multi-air-gap resistive plate chamber detector, which has self-sealing properties, does not need to be placed in the flow box, and can work independently, thereby saving the cost of making the flow box and shortening The aeration time and gas exchange time required for the preparation before the experiment were specified.

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.
