Abstract
A detector for adjusting the convergence of beams at the point of interaction of the MPD (multi-purpose detector) installation at the NICA collider (nuclotron-based ion collider facility) is discussed. Simulation of the detector operation for Au + Au collisions at √SNN =11 GeV is calculated. It is shown that background events from scattering on residual gas give a negligible contribution to the detector’s samples. It is discussed how to use a detector to adjust beam alignment. The calibration procedure for obtaining absolute luminosity in the MPD interaction zone with the help of this detector is considered.
