Abstract

A method is proposed to align wire spark chambers, which are used as particle detectors in a cosmic-ray muon magnetic spectrometer, by analyzing the trajectories of the muons which traverse the spectrometer through the zero-field region. The displacements and rotations of the chambers relative to each other can be determined by least-squares fitting of the trajectories of these muons to straight lines. The accuracy obtained for an arbitrary configuration of 22 chambers and 500 (simulated) trajectories is better than 0.25 mm.
