Application of Drift Chambers for Research of Cosmic-Ray Muon Bundles

The new coordinate-tracking detector based on drift chambers TREK, for research of ultrahighenergy cosmic rays is under development at National Research Nuclear University MEPhI. At the present, a prototype of the future detector—coordinate-tracking unit based on drift chambers (CTUDC)—is functioning. The prototype consists of 16 drift chambers. Results of experimental series have shown wide capabilities of this type of detectors for registration of muon bundles, including bundles with high density of particles. Results of operation of the prototype and prospects of developing a full-size detector TREK are presented.
