Wetting properties of liquid lithium on select fusion relevant surfaces
Research into lithium as a plasma facing component material has illustrated its ability to engender low recycling operation at the plasma edge leading to higher energy confinement times. Introducing lithium into a practical fusion device would almost certainly require the lithium to be flowing to maintain a clean lithium surface for gettering. Several conceptual designs have been proposed, like...
متن کاملExperimental studies of lithium-based surface chemistry for fusion plasma-facing materials applications
Lithium has enhanced the operational performance of fusion devices such as: TFTR, CDX-U, FTU, T-11 M, and NSTX. Lithium in the solid and liquid state has been studied extensively in laboratory experiments including its erosion and hydrogen-retaining properties. Reductions in physical sputtering up to 40– 60% have been measured for deuterated solid and liquid lithium surfaces. Computational mode...
متن کاملProgress in liquid crystal chemistry
Since their discovery in 1888 by the botanist Friedrich Reinitzer, who studied the melting behavior of cholesteryl benzoates, liquid crystals have developed from a mere curiosity to a highly interdisciplinary research field, with LC displays being the most important application to date [1,2]. However, besides the use of thermotropic liquid crystals for display technology many other applications...
متن کاملLithium as a Liquid Limiter in FTU
The experimental results of the use of a liquid lithium limiter on FTU are presented. To avoid droplet generation by JxB forces we have adopted a limiter with a capillary porous system configuration. Lithization of the vacuum vessel is performed by exposing lithium limiter to the plasma boundary for three subsequent plasma discharges after that it is extracted. Strong reduction of the recycling...
متن کاملLiquid Lithium Wall Experiments in CDX-U
The concept of a flowing lithium first wall for a fusion reactor may lead to a significant advance in reactor design, since it could virtually eliminate the concerns with power density and erosion, tritium retention, and cooling associated with solid walls. Sputtering and erosion tests are currently underway in the PISCES device at the University of California at San Diego (UCSD). To complement...
