Fundamental and applied problems concerning the interaction of particle beams with matter in a magnetic field have been studied.
For the first time the process of propagation of a fast antiproton in an electron gas has been studied within the quantum field approach; electric susceptibility of a magnetized electron gas has been found with account of anisotropic temperature; an antiproton propagation through electron gas has been analyzed in the limit of large transferred momentum (close collisions) in the first and the second Born approximations; energy loss of a charged particle in an electron gas has been found with account of electron temperature.
The scientific innovation consist in considering the influence of electron gas temperature, its anisotropy, magnetic field and charge sign on energy loss of a charged particle in a magnetized electron gas using the quantum field approach.
The importance of the obtained results is based on the need of ion beams of high quality in experiments at the modern accelerator facilities. For instance, a new international accelerator facility FAIR (Facility for Antiproton and Ion Research) is being constructed at GSI (GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany). In the frame of the FAIR project it is planned to use for the first time the electron cooling of antiprotons at HESR (High Energy Storage Ring) facility.
