Hydrogen ion implantation into liquid lithium

Phenomenon of nonthermal ions and hydrogen atoms bonding in liquid lithium (introdUction), which can be widely applied in vacuum systems for fusiop devices has been studied experimentally. Technique of creation in high vacuum of liquid lithium target, free of lithium compoUnd films, is developed. Measurements of introduction of molecular ions H2+ with the energy 5 and 10 keV into liquid lithium for the temperature range 200-400 deg C and for solid lithium for doses (1-8)1018 proton/cm2 are made. Introduction coefficients into liquid lithium is not worse than 90% for solid one - 40-70%. Working temperature of lithium should not be increased above 300-320 deg C as already at 350 deg C (Psub(li)--1x10-5 Tor) metal starts to conside, rably dust isolators
