ON  THE  CALCULATION  OF  CHARGET  PARTICLE 
PATHS  NEAR  CURVILINEAR  SURFACES

Institute for Analytical Instrumentation RAS, Saint-Petersburg

    The paper presents a method for calculating trajectories near curvilinear surfaces, which consists of posi-tioning, interpolation and calculation proper stages. Twelve kinds of calculation region boundary intersections with the rectangular grid meshes were established. An algorithm has been developed for interpolating electro-static field functions over the grid mesh portion formed by the calculation region boundary intersection with the grid mesh.
