在GAMMA 10串联磁镜的塞区，当电子回旋加热（ECH）形成静电电子俘获势时，观察到一种高原状的电子分布函数。此外，伴随着热分离区域内分布函数的差异，还观察到由于千伏范围的热垒而产生的显著热隔离效应。这些新发现以及千伏范围内离子约束势和热垒势之间的关系，始终支持科恩强电子回旋加热理论的有效性。
A plateau-shaped electron distribution function is observed when an electrostatic electron-trapping potential is formed by the electron cyclotron heating (ECH) in the plug region of the GAMMA 10 tandem mirror. Also, a remarkable thermal isolation effect due to a kV-range thermal barrier is observed along with the difference between distribution functions in thermally separated regions. These new findings as well as the relation between ion-confining potentials and thermal-barrier potentials in the kV range consistently support the validity of Cohen's strong ECH theory.
