摘      要：Time Projection Chamber(TPC)was developed by *** in 1974[1],which is a gas-filled detector capable of providing three-dimensional tracking *** electron-ion pairs are created when the incident ions pass through the *** the action of the electric field,the electrons will be accelerated towards the *** induced charges from the segmented readout pad can give us the two-dimensional trajectories on the anode ***,the relative drift time of the electrons provides the information of the third *** the projection and the relative drift time of the electrons,we can reconstruct the 3D track of the original charged particles in the gas detector[2].
