A high-resolving, simple and compact electrostatic energy analyser based on a cylindrical bounded field, intended for measurements of parallel flows of charged particles is described. The operation regimes with a second-order focusing mode for several configurations were found, and energy response and energy resolution ability were calculated. It is shown that focusing sharpness and energy resolution increase with the relation of the radius of an outer cylinder to that of an inner one. A combination of high energy resolution ability with high transmission and simple design makes this instrument very promising for a wide range of scientific and technological applications, in particular, for plasma investigations in the laboratory and in space.
