The coordinate-tracking setup based on the drift chambers for ultrahigh-energy cosmic ray investigations
The project of the coordinate-tracking setup based on the drift chambers, designed for a joint operation with Cherenkov water detector NEVOD is presented. The use of large drift chambers (4000x508x112 mm³), developed in IHEP for experiments at the neutrino channel of U-70 accelerator, will allow to create a unique large-scale detector of 270 m² area for registration of multi-particle events at large zenith angles generated by ultrahigh-energy cosmic ray particles. The results of the study of characteristics of drift chambers in the flux of cosmic ray muons including their operation with other systems of the experimental complex NEVOD are described. Basing on results of simulation of detection of near-horizontal muons by drift chambers and Cherenkov water detector, a block-diagram and main elements of the trigger and DAQ systems for new experimental setup were developed. The project of deployment of the drift chambers around the water Cherenkov detector is presented.
