Technical overview of active target time projection chamber
The time projection chamber(TPC)is a well-known tracking detector which has been widely used in high-energy physics experiments.But nowadays it becomes a new fashion to be applied in low-energy nuclear physics experiments.It is very likely for TPC to reconstruct the 3-dimentional dynamics completely due to the smaller volume and a relatively large energy ranges.The gas filled in the TPC working chamber can be had as the working media as well as the target material.In that case,the TPC can also regarded as the so-called active-target TPC(AT-TPC).In order to realize the mentioned-above functions,the micro-structural gas amplifier is introduced into the detector structure and the 3-dimentional track reconstruction algorithm into data analysis.This paper introduced the working principle of the AT-TPC whose unique advantage was presented by comparing with the tradi-tional solid target.As well the related technique involved in the design of the AT-TPC was summa-rized,such as the design of the cage,the selection rule of the working gas,the gas amplification tech-nique and readout technique.The data analysis processing and method were also described.
