在先进的环形加速器中，电子回旋加热过程中观察到的环形电流被认为是自举电流。通过系统扫描极向磁场的四极矩(形变)和偶极矩(磁轴移动)，观测到的电流在+4到{-2}kA的范围内，在大小和参数依赖性上与新经典理论的预测很好地一致。结果表明，星光器中的自举电流可以外部控制，并且可以实现零电流操作。
The toroidal current observed during electron cyclotron heating in the Advanced Toroidal Facility torsatron is identified as bootstrap current. The observed currents, ranging between +4 and {minus}2 kA, agree well with predictions of neoclassical theory in magnitude and parametric dependence, as determined by systematic scans of quadrupole (shaping) and dipole (magnetic axis shift) moments of the poloidal magnetic field. It has been shown that the bootstrap current in a stellarator can be externally controlled, and zero-current operation can be achieved.
