The Helicity Injected Torus programme has made progress in understanding relaxation and helicity injection current drive. Helicity conserving MHD activity during the inductive(ohmic) current ramp demonstrates the profile flattening needed for coaxial helicity injection (CHI). Results from cathode and anode central column CHI pulses are consistent with the electron locking model of current drive from a pure n = 1 mode. Finally, low density CHI, compatible with ohmic operation, has been achieved. Some enhancement of CHI discharges with the application of ohmic heating is shown.

ヘリシティ入射トーラス計画は、緩和とヘリシティ入射電流駆動の理解において進展を遂げた。誘導(オーミック)ランプ中のヘリシティ保存MHD活動は、同軸ヘリシティ入射(CHI)に必要なフラット化された電流分布を示している。陰極および陽極中心柱CHIパルスからの結果は、純粋なn = 1モードによる電流駆動の電子閉じ込めモデルと一致している。最後に、オーミック動作と両立する低密度CHIが達成された。オーミック加熱の適用によるCHI放電の向上の一部が示されている。
