Effects of finite beta and radial electric fields on neoclassical transport in the Large Helical Device

The effects of finite beta and radial electric fields on neoclassical transport in LHD are investigated with the Drift Kinetic Equation Solver (DKES) code. In the finite- beta configuration, even orbits of deeply trapped particles deviate significantly from magnetic flux surfaces. Thus, neoclassical ripple transport coefficients in the finite- beta configuration are several times larger than those in the vacuum configuration under the same conditions of temperatures and radial electric fields. When the plasma temperature is several kiloelectronvolts, a bifurcation of the electric fields appears under the ambipolarity condition. The E*B drift due to the resultant sufficiently large radial electric fields causes the orbits to curve so that they more closely follow the pressure surfaces and improves significantly the transport coefficients in the finite- beta configuration

有限ベータと径電場がLHDにおける新古典輸送に及ぼす効果を、Drift Kinetic Equation Solver(DKES)コードを用いて調べた。有限ベータ配位では、深く捕捉された粒子の軌道でさえも磁気面から大きくずれる。したがって、有限ベータ配位における新古典リップル輸送係数は、同じ温度および径電場の条件下で、真空配位におけるものより数倍大きい。プラズマ温度が数キロ電子ボルトの場合、両極性条件の下で電場の分岐が現れる。結果として生じる十分に大きな径電場によるE×Bドリフトは、軌道が圧力面により密接に追従するように曲がることを引き起こし、有限ベータ配位における輸送係数を有意に改善する。
