The Application of Multi-Wire Drift Chambers in Cosmic Ray Research

摘要

Multiwire drift chambers designed for the neutrino experiment at the IHEP U-70 accelerator have found a new application in the MEPhI experiment focused on the detection of ultrahigh-energy cosmic rays. Their high durability and fine spatial and angular characteristics make these chambers perfectly suitable for such studies. The drift chambers were tested at MEPhI and used in constructing the CTUDC coordinate-tracking setup, which operated together with the NEVOD water Cherenkov detector and the DECOR detector. The results of the studies of the parameters of drift chambers in the cosmic-ray flux at test benches and in the CTUDC setup are presented.
