在实验室制作了低压多线比例室(LPMWPC)并进行了系统测试。腔室的位置分辨率约为0.5mm，时间分辨率约为1.5ns。对于中低能量的轻核、光束强度低于105pps的检测效率高于90%。此类探测器适用于监测放射性离子束，其一般特点是强度低、光斑大。新读出技术的应用可以提高光束强度能力。
Low Pressure Multi-Wire Proportional Chambers (LPMWPC) were made in the laboratory and the systematic tests were carried out. The position resolution of the chamber is about 0.5mm and the time resolution is about 1.5ns. The detection efficiency is higher than 90% for light nuclei at low and intermediate energies, and for beam intensities lower than 105pps. This kind of detector is applicable for monitoring the radioactive ion beam which is in general characterized by low intensity and large spot. Application of new read-out techniques may allow to improve the beam intensity capability.
