Abstract :
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 0.5 mm and the time resolution is about 1.5 ns. The detection efficiency is higher than 90% for light nuclei at low and intermediate energies, and for beam intensities lower than 105 pps. 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.
