【Abstract】 A medium heavy ion focal-plane detector system (500mm long) was tested with beam and has been used in nuclear physics experiment, the detector telescope consists of five rectangular proportional counters. The operating gas is 30% CH4 + 70% Ar. In a table experiment, the intrinsic resolution of the position sensitive detector is about 0. 7mm (FWHM), the intergral nonlinearity is better than 0. 2%. In a test experiment at cyclotron, the energy resolution of the AE detector is about 6. 3%, the energy resolution of the E detector is about 10%. The measured results at tandem accelerator with 60 MeV 12C beam for the pressure of 0. 5X 105 Pa are- the intrinsic resolution of the position sensitive detector is about 1. 3mm, the integral nonlinearity is better than 0. 62% 5 the energy resolution of the AE detector is about 6 % ; the energy resolution of the E detector is about 31%.更多还原
