Abstract

A series of experiments with a fully ionized turbulent lithium plasma is described. Discharges with a heat flux density onto the wall of 1–3 kW/cm2 and an electron density of ∼1015 cm−3 are obtained. The energy can be transferred to the wall by both Li+ and Li++ ions. The measurements show that the photon flux corresponding to the main resonant transition of lithium atoms is a factor of 104–105 less than it could be if all the ions arriving at the wall recombined there. A mechanism is proposed for energy transfer onto the wall via the recombination of Li++ ions to Li+ ions in the cold wall region of the discharge and the subsequent energy emission by Li+ ions.
