摘要: The ability to use liquids as plasma-facing components (PFCs) surfaces depends on their interaction with the plasma and strong magnetic field. One important issue for moving liquid is entrain particles that strike surface while accommodating high heat loads. Particle entrapment could determine viability of specific candidates successful renewable PFC surfaces. To study this problem, an analytical model developed implemented using HEIGHTS package takes into account kinetics particle injection, motion interactions lattice, ultimate release from surface. An question whether He can also be pumped by rather than standard vacuum system approach. Impinging at low density PFCs may harder pump pumping techniques. We find, in analysis, a reasonable chance adequate helium trapping flowing lithium PFC.
