The interaction between a wide ultrarelativistic fully ionized plasma beam and a magnetic barrier is studied numerically. It is assumed that the plasma beam is initially homogeneous and impacts with the Lorentz factor Γ0>>1 on the barrier. The magnetic field of the barrier B0 is uniform and transverse to the beam velocity. When the energy densities of the beam and the magnetic field are comparable, α=8πn0mpc2(Γ0-1)/B20~1, the process of the beam-barrier interaction is strongly nonstationary and the density of reversed protons is modulated in space by a factor of 10 or so. The modulation of reversed protons decreases with decrease of α. The beam is found to penetrate deep into the barrier provided that α>αcr, where αcr is about 0.4. The speed of such a penetration is subrelativistic and depends on α. Strong electric fields are generated near the front of the barrier and electrons are accelerated in these fields up to the mean energy of protons, i.e., up to ~mpc2Γ0. The synchrotron radiation of high-energy electrons from the front vicinity is calculated. Stationary solutions for the beam-barrier collision are considered. It is shown that such a solution may be only at α<~0.2-0.5, depending on the boundary conditions for the electric field in the region of the beam-barrier interaction.
