STRELA experimental setup for studying charge-exchange processes

The STRELA experimental setup designed for studying charge-exchange processes in deuteron-proton collisions at energies above 1 GeV is described. The setup is a one-arm magnetic spectrometer the main elements of which are drift chambers. The setup has been tested by irradiation in a deuteron beam with a momentum of 3.5 GeV/c at the Nuclotron accelerator complex (Laboratory of High Energy Physics, Joint Institute for Nuclear Research (JINR)). Algorithms for track searching and reconstruction in drift chambers have been developed and tested using real events. The attained spatial resolution of the chambers is in the range of 90–120 μm, which is sufficient for studying the process we are interested in.
