Low-pressure multi-wire drift chambers have been developed to track high-intensity radioactive isotope beams at the energies of around 200 MeV/nucleon. In order to minimize the effect of multiple scattering by radioactive isotope beam, the thickness of the detectors were minimized by using isobutane gas at low pressure (10 kPa). The performance of the position resolution, the tracking efficiency, and the beam intensity capability were evaluated as a function of atomic number and applied voltage. As a result, an overall position resolution of 300 μm was achieved for radioactive isotope beams with an intensity of 1 MHz. The details of the design specifications and performances of the low-pressure multi-wire drift chambers are described.
