  Different types of ground-based detectors have been developed and deployed
around the world to monitor and study CR variations. We have designed,
constructed and operated a three layer small (20x20 cm2) multiwire proportional
chamber MWPC telescope for cosmic ray muon observations. In this paper, the
technical aspects of this detector will be briefly discussed. The abilities of
the telescope in detecting high nergy cosmic ray muons (primaries higher than
20 GeV) were established. The telescope performs well in this sense and showed
comparable results with a 1 m2 scintillator detector.
