内容記述 | Electron acceleration to ultrarelativistic energies by an oblique magnetosonic shock wave is studied. First, the maximum electron energy is analytically obtained with new simple calculations. The physical mechanism is also discussed in detail. In the wave frame, electrons reflected near the end of the main pulse region, which will be trapped, gain energy from the electric potential and constant electric field E_{y0} perpendicular to the external magnetic field. For certain plasma parameters, these electrons can move a long distance in the direction of E_{y0} and obtain a great amount of energy from E_{y0} . It is argued that the trapped electrons can hardly escape from the shock wave. Next, one-dimensional, relativistic, particle simulations are carried out. Theoretical estimates such as the maximum electron energy are found to be in good agreement with the simulations. Simulations also show that the number of trapped electrons continually increases with time. | |||||
