Abstract
The BM@N experiment is considered as the first phase of NICA Mega science project. The energy of the beam will vary from 1 to 6 GeV/u. The beams delivered by Nuclotron will be of different types from protons to Au. The ability to reconstruct the beam momentum with high precision is one way for showing that the tracking detectors are tuned in the right way and the reconstruction procedure performs well. A quick overview of the experimental setup is given in the work along with the description of some of the main tracking detectors. The beam momentum reconstruction procedure is described and results are presented for different values of the beam energy.
Highlights
The Baryonic Matter at Nuclotron (BM@N) is the first step of the realization of the Nuclotron-based Ion Collider fAcility (NICA) mega-science project [1]
This paper presents the results of the beam momentum reconstruction procedure using two tracking detector systems: Multi-Wire Proportional Chambers (MWPC) and Drift Chambers (DCH)
The beam trajectory was positioned by the MWPC system at 0o with an error less than 1%
Summary
The Baryonic Matter at Nuclotron (BM@N) is the first step of the realization of the Nuclotron-based Ion Collider fAcility (NICA) mega-science project [1]. The purpose of the BM@N experiment is to study the interactions of relativistic heavy ion beams delivered by the Nuclotron with fixed targets [2]. The Nuclotron facility is able to provide various types of beams with kinetic energies from 1 to 6 GeV per nucleon. The accuracy assessment of the main detector systems performance is one of the main tasks at the moment. This paper presents the results of the beam momentum reconstruction procedure using two tracking detector systems: Multi-Wire Proportional Chambers (MWPC) and Drift Chambers (DCH). The accuracy of this reconstruction provides a measure to the performance capabilities of these two detector systems
