INVESTIGATION OF THE NEUTRINO CHANNEL AT THE U-70 ACCELERATOR COMPLEX WITH PARENT PARTICLE BEAM DEFLECTION

Principle optical scheme of the neutrino beam production channel based on the accelerator complex U-70 is considered. In order to extract the required pulse interval of π-mesons, a two-magnetic system with a “field” lens with a one-way deflection of the parent particle beam and full compensation of the dispersion is proposed. In this scheme the decay part of the channel is deflected with respect to the direction of the primary proton beam aiming at the target. The main computational characteristics of the neutrino beam at the far detector at a distance of 2595 km from the end of the decaying part of the channel as well as the parameters of the parent π mesons at the beginning of the decaying part are discussed.
