摘　　要：气体探测器有成本低廉、制备简单、性能可靠和方便使用等特点。研制了一种5层板结构的延迟线平行板雪崩电离室(PPAC),用于兰州放射性束流线(RIBLL)上开展的实验。在57.6MeV/u的6He束流条件下测试了这种探测器对高能轻粒子的适用性,得到了位置分辨为1.8mm(FWHM),时间分辨为2.6ns,以及可靠的探测效率。The gas detectors have the characteristics of low cost,easy preparation,reliable capability and convenient for use etc.A delay-line parallel-plate avalanche counter（PPAC）with five plates has been developed for the experiments at Radioactive Ion Beam Line in Lanzhou（RIBLL）.The applicability of counter for high energy light ion has been tested with 57.6 MeV/u 6↑He beam.A position resolution of -1.8 mm（FWHM）and a timing resolution of -2.6 ns are achieved.The detection efficiency is reasonable.
