Side window type crossing radiation gas detector

Abstract

The invention provides a side window type crossing radiation gas detector. The radiator of the detector is composed of a foil material and a gasket frame, the foil material is bonded to the gasket frame, and then all layers of foils are stacked together to form a regular radiator of a multi-layer structure formed by stacking materials with different dielectric constants; the gas detector comprisesa field cage, a double-layer thick gas electron multiplication membrane plate, an anode plate and a cavity, wherein the field cage is formed by splicing PCBs, the top surface of the interior of the field cage is a copper-clad cathode plate, copper bars are distributed on the side surface of the interior of the field cage at equal intervals, each layer of copper bars are connected through a fixed-value resistor, and the chamber and the anode plate are screwed up through screws to form a closed gas detector; the readout electronics system comprises a front end plate and a rear end data acquisition plate. The signals passing through radiation photons can be effectively distinguished, and energy calibration is carried out on high-energy charged particles. The gas detector has the advantages that large-area manufacturing is easy, the counting rate is high, and the spatial position resolution reaches the sub-millimeter level.

Description

technical field [0001] The invention relates to a gas detector, in particular to a side-window radiation-penetrating gas detector, which belongs to the field of particle detection. Background technique [0002] The determination of the absolute energy scale of the space high-energy cosmic ray experiment calorimeter is extremely important for accurate measurement of the energy spectrum, especially for the study of the absolute energy scale of cosmic rays in the TeV energy range, it is very necessary to carry out space experiments. The Transition Radiation Detector (TRD) can be used to calibrate the energy of the space experiment calorimeter, which can greatly improve the measurement accuracy of cosmic rays in the TeV energy region of the calorimeter, and can be applied to future large-scale direct detection experiments of space cosmic rays , as a technical reserve for future large-scale space experiments. [0003] At present, through-radiation detectors are widely used in hi...
