A prototype of Multi-Wire Proportional Chambers (MWPC) has been fabricated for the study of its various characteristics. The detector contains gold-coated tungsten wires (20 μm diameter) on the anode frame, with a pitch of 2.8 mm. The gap between the anode and the cathode is 3 mm and the gap between anode and read-out is also 3 mm. Detailed study of MWPC in terms of gain, energy and timing resolution and efficiency measurements have been performed. The detector has been operated using Ar/CO2 gas mixtures with 70:30 and 90:10 ratio. Energy spectrum of 55Fe X-ray source is obtained for the detector. The gain and energy resolution of the detector were calculated using X-ray spectrum. Time resolution is obtained ∼10 ns.
