ACCELERATION OF ELECTRONS AT A CURVED SHOCK

The paper deals with the acceleration of electrons at a nearly perpend icular curved shock wave and results are compared with the case of a p lane shock wave. We formulate the equations of motion of an electron i n adiabatic approximation and solve them in a special case. The result s show that the energy gain of reflected electrons at a curved shock d epends on the ratio of the radius of curvature to the shock thickness; for a low ratio the energy gain is significantly lower than at a plan e shock, while the energy gain of transmitted electrons is approximate ly the same as at a plane shock. The analytical solution provides a to ol for direct calculations of fluxes of accelerated electrons near the curved shock of given parameters.
