The design of time projection chamber for fission cross-section measurements

In order to measure the cross-sections of the major actinides with high precision, a TPC is proposed taking advantage of its ability of particle track reconstruction. In this study, a Monte Carlo simulation was developed to design the fission Time Projection Chamber(fTPC) system. Based on the simulation, we optimized the size of the pad, the gas pressure and the parameters of the readout electronics which have a great influence on the system performance.
