Study on Position Resolution of Low Pressure Multi-wire Proportional Chambers

    Graphical Abstract
    • Abstract
  • Low pressure multi-wire proportional chamber(LPMWPC) provides excellent position and time signals for the radioactive beam induced reactions. By using the 241Am α source, the influencing conditions on the position resolution, including the voltage and the working gas pressure（800-1 330 Pa）, were studied. The best position resolutions at different gas pressures are less than 1 mm. Considered the time resolution and detection efficiency, it is necessary to make the gas pressure as high as possible.
