Technological aspects of lithium capillary-pore systems application in tokamak device

Abstract

The paper concerns two problems. First, the usage of a lithium material basing on capillary-pore systems as a material of rail limiter working in conditions of considerable thermal ( 10 MW/m 2 ) and electromechanical loads caused by interaction with a tokamak plasma in a T-11M tokamak. The second problem is the influence of a modification of recycling for hydrogen, deuterium and helium due to lithium sputtering and deposition on the discharge conditions.

Liquid metals as alternative solution for the power exhaust of future fusion devices: status and perspective

“…As part of the application of liquid metals, stabilizing concepts have hence been proposed including the use of capillary action to counteract disruption and jxB forces. cooled structure together with a liquid metal reservoir is used in the so called Capillary Porous System (CPS) [15,27,16,9,13,28,12]. To facilitate capillary action, the open radius of the porous structure or mesh is typical in the sub-mm range (10 − 200µm).…”

Basics of Fusion-Fissison Research Facility (FFRF) as a Fusion Neutron Source

“…In contrast, FFRF relies on development of plasma regimes, which emerged during the last decade (since Dec. 1998) [3][4][5][6][7][8]. The goal is to simplify the plasma regimes and eliminate numerous uncertainties in the current tokamak plasma physics.…”

Fusion-Fission Research Facility (FFRF) as a Practical Step Toward Hybrids

“…The fundamental shift back to the basic line in magnetic fusion was made in Dec. 1998 when T-11M [5,6] experiments have demonstrated the outstanding abilities of lithium coating in absorbing deuterium plasma particles. It was immediately understood that the lithium plasma facing layer can eliminate the recycling and prevent plasma edge cooling by the cold neutrals.…”
