摘 要：A gas detector 140×140×140 mm^(3)in size,termed the compact active target time projection chamber(CAT-TPC),was developed in this study to measure resonant scattering associated with cluster structures in unstable *** CAT-TPC consists of an electronic field cage,double-thick gas-electron-multiplier foils,a general-purpose digital data acquisition system,and a newly developed two-dimensional strip-readout *** CAT-TPC was operated using a^(4)He(96%)+CO_(2)(4%)gas mixture at 400 *** working gas also serves as an active target for tracking charged *** overall performance of the CAT-TPC was evaluated using a collimated a-particle source.A time resolution of less than 20 ns and a position resolution of less than 0.2 mm were observed along the electron drift *** images of incident trajectories and scattering events can be clearly reconstructed under an angular resolution of approximately 0.45 degree.
