报告了Heliotron J在初始实验阶段获得的结果。电子束映射的磁性表面在一个减少的直流磁场lias显示，所观察到的表面是在基本协议的基础上计算的测量周围的设备的环境场。对于53.2GHz的二次谐波ECH氢等离子体，与Heliotron E相比，在Heliotron J中观察到了相当宽的TE_（02）模击穿和加热共振范围。当ECH注入功率达到400 kW时，在没有优化密度控制的情况下，获得了高达0.7 kJ的抗磁储能。
Results obtained in the initial experimental phase of Heliotron J are reported. Electron beam mapping of the magnetic surfaces at a reduced DC magnetic field lias revealed that the observed surfaces are in basic agreement with the ones calculated on the basis of the measured ambient field around the device. For 53.2 GHz second harmonic ECH hydrogen plasmas, a fairly wide resonance range for breakdown and heating by the TE02 mode has been observed in Heliotron J as compared with that in Heliotron E. With ECH injection powers up to approximate to 400 kW, diamagnetic stored energies up to approximate to0.7 kJ were obtained without optimized density control.
