Description
technical field [0001] The invention relates to the field of nuclear technology or nuclear detection, in particular to an online track reconstruction data acquisition system and reconstruction method based on a gas detector. Background technique [0002] In 1997, CERN scientist Fabio Sauli invented a new microstructure gas detector GEM (gaselectron multiplier). The GEM detector etches dense micropores on the Kapton film coated with copper on both sides, changes the electric field distribution in the working gas, and thus realizes the avalanche amplification of the electronic signal. It has excellent position resolution and good radiation resistance, and can Features such as working under high count rate conditions. Based on a variety of advantages, it has been developed rapidly in the world in recent years. It is mainly used in high-energy particle physics experiments such as the readout detector of the upper track chamber of the detector of the future International Linear ...
