Abstract
The methods for reconstructing the coordinates of charged particles in gaseous detectors with cathode readout are analyzed in detail. The spatial resolution is investigated using spatial-reconstruction procedures based on the known relations and the new formulas proposed in the paper. The use of this method is illustrated by processing the beam-test data of the charged-particle veto detector of the proton spectrometer for the ALICE experiment at the Large Hadron Collider (CERN). The spatial resolution of the detector based on the multiwire proportional chamber with cathode-pad readout (pad dimensions are 22 × 10.7 mm, the anode-wire pitch is 5.65 mm, and the anode–cathode gap is 5.5 mm), measured along and across the anode wires, is σ x ≅ 0.14 cm and σ y ≅ 0.15 cm, respectively.
