Characteristics of lithium thin films under deuterium ion implantation

Plasma-wall interactions and plasma behaviour in fusion devices with liquid lithium plasma facing components

“…As it was shown [5], the penetration depth of 600 eV hydrogen in liquid Li is not more than 1 lm. The experiments with steady state electron beam [11] showed that the maximum power load of such CPS in lithium recovery regime can be as high as 20 MW/m 2 .…”

“…Liquid lithium splashing and tritium retention are the traditional arguments against the liquid lithium use in tokamaks. However, several experiments which were performed in Russia (tokamak T-11 M [3]), USA [4] and Japan [5] showed that the trapped hydrogen isotopes can be removed from the lithium target by heating only up to 400-500°C.…”

“…Fig. 21 shows the temperature dynamics of deuterium removal from liquid lithium for three known experiments [3][4][5] in semi-logarithmical scale. In temperature interval 300-500°C we can approximate its behaviour by $ exp-E k /T again.…”

The tests of liquid metals (Ga, Li) as plasma facing components in T-3M and T-11M tokamaks

“…To avoid helium sorption it was sufficient to heat the T-11M chamber wall up to 50-100 • C. The Li-limiter heating after plasma experiments showed a start of deuterium desorption from lithium at temperatures higher than 320 • C [8]. As it was shown later by beam experiments [11] and in process of limiter cleaning in T-11M, the lithium heating up to 500 • C seems to be sufficient to remove all deuterium and probably tritium also. The difference of helium and deuterium sorption may be used for its separation in the future reactor.…”

From Carbon Nanostructures to New Photoluminescence Sources: An Overview of New Perspectives and Emerging Applications of Low‐Pressure PECVD

“…[141][142][143] Li-based coatings have been less used thus far due to technical difficulties for the deposition of homogeneous films. [144][145][146] An efficient PECVD scheme has not yet been achieved, and Li is either evaporated or exposed to the hot plasma for coating. Present evidence suggests that Libased coatings have better properties than B for hydrogen recycling.…”
