Loss estimation of TWDEC for a D-3He FRC fusion reactor
- 1. Institute of Engineering Mechanics, Univ. of Tsukuba, Tsukuba, Ibaraki (Japan)
Description
Loss mechanisms of TWDEC (Traveling Wave Direct Energy Converter) for a D-3He fueled FRC fusion reactor are studied with a numerical analysis. (1) The self-excitation of traveling wave has been attained by the one-dimensional analysis, which shows the conversion efficiency is about 70 to 73%. (2) Axisymmetric two-dimensional analyses have shown that the loss related to the two-dimensional effect without collision with grids is about 5%. (3) The loss related to the collision with grids is the most important, being about 11%. (4) Effects of secondary electrons produced by the collision with grids are rather small and sub-rings can suppress effects of secondary electrons. (5) The loss related to the leaked 3.6 MeV 4He is about 45 to 60% of the total energy of leaked 4He. (6) The gross efficiency of TWDEC is estimated over 60%. (author)
