Recent Results of Experiments on the Gas Dynamic Trap

This report summarizes the results of experimental investigations obtained during the last five years at the Gas Dynamic Trap experimental facility of the Budker Institute Novosibirsk. Due to an essential upgrade of the main components performed in this period, the following plasma parameters have been achieved: electron temperature - 90-110 eV, fast ion density - up to 0.8*10^13 cm^-3, mean energy of fast ions - 5-8 keV, plasma-ß - 15-20%. The paper describes the following investigations: effect of wall conditioning on neutral gas dynamics, longitudinal electron heat flux, confinement of the high-ß two-component plasma, fast ion parameters under high-ß conditions, fueling of the target plasma by gas puffing. It presents results of measurements and of calculations.
