螺旋度注入环面方案在理解弛豫和螺旋度注入电流驱动方面取得了进展。在感应（欧姆）电流斜坡期间的螺旋度守恒MHD活动表明了同轴螺旋度注入（CHI）所需的轮廓平坦化。阴极和阳极中心柱CHI脉冲的结果与纯n = 1模式的电流驱动的电子锁定模型一致。最后，低密度CHI，兼容欧姆操作，已经实现。一些增强CHI放电与欧姆加热的应用程序。
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.
