In the scientific-educational center NEVOD the new coordinate-tracking unit on drift chambers (CTUDC) has been created [1]. Its inclusion in the unique experimental complex allowed to significantly expand the existing possibilities for studying high-density muon bundles (up to 10 particles per square meter). During the development and operation of the first installation in the world of this type, it was possible to resolve a number of issues related to the modes of joint operation of large-area multi-wire drift chambers and their recording electronics with other installations of the complex, methods for reconstructing of multiparticle events and organizing the necessary technological systems. The accumulated experience will be used in the development of the largest coordinate-track detector for the registration of cosmic rays TREK [2] with an area of over 250 square meters.
The report describes the registration system of the installation [3], the results of the study of its time characteristics. The prospects for creating a similar system for a new detector, approaches to the development of new time-to-digital converters are discussed. The work was performed at the Scientific and Educational Center NEVOD MEPhI with the financial support of the Russian Foundation for Basic Research in the framework of the research project No. 18-32-00687.
