Introduce the manufacturing process, working principle and performance test of the telescope made up of trapezoidal ionization chamber and position sensitive semiconductor detector. As a tool for nuclear reaction measurement, the detector plays a very important role in nuclear physics experiments. This detector telescope is made of a gas-sensitive ionization chamber that measures ΔE loss plus a position-sensitive semiconductor detector that measures the residual energy, E. It gives full play to the respective advantages of the gas ionization chamber and the position sensitive semiconductor detector. Its excellent performance is well demonstrated in the study of 102.00-109.50 MeV19F +51 V dissipation reaction excitation function.
