Feasibility Study of Neutron Kinematic Reconstruction Using the Time-of-Flight Data of BINA Scintillators

Some neutrons in the final state can deposit a fraction of their energies in the BINA detection system, making it impractical to extract neutron kinematic parameters using ADC signals. The Multi-wire proportional chamber is only suitable for registering the hit positions charged nucleons . In this article, a new alternative approach is presented and applied using the time-of-flight data of neutrons originating from the three-body breakup channel of deuteron-deuteron (dd) scattering at 65 MeV/Nucl. to extract neutrons’ kinematical parameters . To achieve this, the hit positions of particles in scintillator detectors along with their corresponding time-of-flight (TOF) data are used to determine the X and Y coordinates, and subsequently, the scattering angles (polar and azimuthal) of neutrons. Once the scattering angles of neutrons (two variables) and the kinematical parameters of one of the detected charged nucleons (three variables)are known, the energy of neutron can be is extracted using momentum and energy conservation laws. To validate the proposed method, the kinematical parameters of protons obtained through this approach were compared with those obtained using the BINA detection system. Reconstructing the kinematics of neutrons as the final-state particles allows for further exploration of various hadronic channels of dd scattering process where neutrons are rolled as a detected as final-state particles. This enables investigation into the isospin dependence of nuclear potential as well as Coulomb effects .
