SOME VARIATIONAL PROBLEMS ON THE ACCELERATION OF CARRIER GAS IN STRONG ELECTROMAGNETIC FIELDS (NEKOTORYE VARIATSIONNYE ZADACHI OB USKORENII PROVODYASHCHEGO GAZA V SILNYKH ELEKTROMAGNITNYKH POLYAKH),

Abstract

Two specific problems are posed and solved with respect to the maximum efficiency of plasma acceleration in crossed magnetic and electrical fields when electromagnetic forces are much greater than the forces of pressure. The first problem is to determine that distribution of channel cross sectional area, potential difference and intensity of external magnetic field along the channel length which will produce the maximum plasma velocity for a fixed channel length. The second problem is to determine values of s(x), h(x) and phi(x) assuring minimal losses due to Joule dissipation, assuming that the plasma must be accelerated from v sub zero to v sub 1 over an assigned channel length.
