Abstract

The Beam–Beam Counters (BBC) are the components of the Spin Physics Detector at the NICA collider. They are designed to perform local polarimetry of the colliding polarized proton and deuteron beams and luminosity control in the beam interaction region. Here, the Monte Carlo (MC) simulation of the BBC operation for proton–proton collisions is presented. The simulations are performed at the center-of-mass energy of 10 GeV using the SpdRoot framework. The results presented include the estimation of the magnetic field influence on the inclusive charged particle production asymmetries and the BBC loads. The selection of the \(pp\) -elastic scattering events in the BBC is also discussed.
