据报道，首次成功通过电子伯恩斯坦波（EBW）对高介电常数球形托卡马克等离子体进行高功率加热。通过从 TST-2 球形托卡马克的低磁场侧注入模式回旋波的模式转换 (MC) 来激发 EBW。随着储存能量和软 X 射线发射的增加，观察到电子加热的证据。增加的发射集中在等离子体核心区域。当 MC 区域的密度梯度足够陡时，加热效率可达到 50% 以上。
The first successful high power heating of a high dielectric constant spherical tokamak plasma by an electron Bernstein wave (EBW) is reported. An EBW was excited by mode conversion (MC) of an mode cyclotron wave injected from the low magnetic field side of the TST-2 spherical tokamak. Evidence of electron heating was observed as increases in the stored energy and soft x-ray emission. The increased emission was concentrated in the plasma core region. A heating efficiency of over 50% was achieved, when the density gradient in the MC region was sufficiently steep.
