Performance of a High-Pressure Hydrogen TPC

摘要

We report on the performance of a high-pressure hydrogen-filled time-projection chamber (TPC) designed to study photon-diffraction dissociation on hydrogen. The TPC consists of two identical 75-cm-long by 45-cm-diameter drift regions filled with H sub 2 at 15 atm. It is used as an active target to measure the polar angles and dE/dx of recoil protons.
