Abstract

A kind of large position sensitive parallel plate avalanche counter(PPAC) was developed at Gas Detector Research Group, Institute of Modern Physics of CAS. Each of the detector with large sensitive area of 244 mm×284 mm, consists of one central cathode, X anode and Y anode. The cathode plane in the middle of detector is a 1.5 μm thick Mylar foil coated with a thin Au-layer on both sides. The position resolution of the PPAC is better than 4 mm, and the time resolution is 0.42 ns. The detectors were used in the fission experiment with 30MeV/u ⁴⁰Ar beam bombarding on a gold target to measure the velocity of the fission fragments at Radioactive Ion Beam Line In Lanzhou(RIBLL). Four PPACs were used and the experiment result showed that a rather high detection efficiency (90.3%) is achieved. The position distribution of fission fragments is given by PPACs, which provides very good experimental data for further theoretical analysis.
