The seal frame 1 has an upper end 107 and a lower end 108 which are opposed to each other in the vertical direction. The upper plexiglass plate 31 is disposed on the upper end 107 and the lower plexiglass plate 32 is disposed on the lower end 108 the upper and lower plexiglass plates 31, 32 are disposed in a vertically spaced apart relationship, defining a sealed chamber 101 between the upper plexiglass plate 31, the lower plexiglass plate 32 and the sealing frame 1. The sealing frame 1 is provided with an air inlet hole and an air outlet hole which are communicated with the sealing cavity 101.

The first avalanche cell chamber 103 and the second avalanche cell chamber 104 are arranged in the left-right direction and the first avalanche cell chamber 103 is disposed on the left side of the second avalanche cell chamber 104. Each of the first avalanche cell chamber 103 and the second avalanche cell chamber 104 includes a plurality of low resistance glass plates 5, and the number of the low resistance glass plates 5 of the first avalanche cell chamber 103 and the number of the low resistance glass plates 5 of the second avalanche cell chamber 105 are the same. The plurality of low-resistance glass plates 5 of each of the first avalanche cell chamber 103 and the second avalanche cell chamber 104 are arranged at intervals in the up-down direction so as to form an air gap 501.
The plurality of low-resistance glass plates 5 of the first avalanche cell chamber 103 and the plurality of low-resistance glass plates 5 of the second avalanche cell chamber 104 correspond to each other one by one in the left-right direction, and the right side surface of the low-resistance glass plate 5 of the first avalanche cell chamber 103 is bonded to the left side surface of the low-resistance glass plate 5 of the second avalanche cell chamber 104 corresponding to each other in the left-right direction.
Each of the first avalanche cell chamber 103 and the second avalanche cell chamber 104 further includes an upper carbon film 61, a lower carbon film 62, an upper conductor 7, and a lower conductor. The upper carbon film 61 is provided between the upper organic glass plate 31 and the low-resistance glass plate 5 corresponding to the uppermost layer of the avalanche cell chamber, and the lower carbon film 62 is provided between the lower organic glass plate 32 and the low-resistance glass plate 5 corresponding to the lowermost layer of the avalanche cell chamber. The upper conductor 7 is connected to the upper carbon film 61 corresponding to the avalanche cell chamber, and the lower conductor is connected to the lower carbon film 62 corresponding to the avalanche cell chamber.
According to the multi-air-gap resistive plate chamber detector 100, the sealing frame 1, the upper organic glass plate 31 and the lower organic glass plate 32 are used for forming the sealing chamber 101, working gas is introduced into the sealing chamber 101 through the gas inlet holes, and the polluted working gas in the sealing chamber 101 is exhausted through the gas outlet holes, so that a working gas environment is provided for the multi-air-gap resistive plate chamber detector 100. When the upper conductor 7 and the lower conductor of each avalanche unit chamber are communicated with an external power supply, a uniform electric field can be formed in the sealed chamber 101, when charged particles pass through the field area, the working gas is ionized, the primary ionization is subjected to avalanche and drift under the action of strong field intensity, and current signals are induced on the upper readout circuit board 41 and the lower readout circuit board 42.
Because the number of the low-resistance glass plates 5 of the first avalanche cell chamber 103 and the second avalanche cell chamber 104 is the same, the low-resistance glass plates 5 of the first avalanche cell chamber 103 and the low-resistance glass plates 5 of the second avalanche cell chamber 104 correspond to each other in the left-right direction, and the right side surface of the low-resistance glass plate 5 of the first avalanche cell chamber 103 is attached to the left side surface of the low-resistance glass plate 5 of the second avalanche cell chamber 104 corresponding to each other in the left-right direction, each layer in the up-down direction of the multi-air-gap resistive plate chamber detector 100 is formed by splicing a plurality of low-resistance glass plates 5, and the sensitive area of the multi-air-gap resistive plate chamber detector 100 is the sensitive area of a plurality of low-resistance glass plates 5 in the same layer.
In the related art, the sensitive area of the multi-air-gap resistive plate chamber detector is the sensitive area of a single low-resistance glass plate, and when the thickness (the size in the vertical direction) of the multi-air-gap resistive plate chamber detector is limited, the sensitive area of the multi-air-gap resistive plate chamber detector is small, so that the multi-air-gap resistive plate chamber detector is difficult to apply to a large-scale experiment. In order to increase the sensitive area of the multi-air-gap resistive plate chamber detector, a plurality of multi-air-gap resistive plate chamber detectors are stacked in a splicing mode, but a large dead area exists in the multi-air-gap resistive plate chamber detector.
Compared with the related art, the multi-air-gap resistive plate chamber detector 100 according to the embodiment of the utility model is not limited by the size of the low-resistance glass plate 5 and has a larger sensitive area. In addition, because a plurality of multi-air-gap resistive plate chamber detectors do not need to be spliced and stacked, the multi-air-gap resistive plate chamber detector 100 according to the embodiment of the utility model is not only more convenient to use, but also can effectively reduce the dead area of the multi-air-gap resistive plate chamber detector 100.
The multi-air-gap resistive plate chamber detector 100 according to the embodiment of the utility model has the advantages of large sensitive area, convenience in use, small dead zone area and the like.
In addition, the multi-air-gap resistive plate chamber detector 100 according to the embodiment of the utility model uses the upper organic glass plate 31, the lower organic glass plate 32 and the sealing frame 1 to form the sealed chamber 101, and uses the working gas in the sealed chamber 101 to provide a working gas environment for the multi-air-gap resistive plate chamber detector 100. Compared with the gas environment which adopts the aluminum box to provide work for the multi-air-gap resistive plate chamber detector in the related technology, the gas environment has smaller gas exchange space, and the problem of internal gas pollution of the detector under the condition of high counting rate can be obviously solved.
