与磁场成斜角的电子回旋发射提供了一种通过改变和约束相对论电子回旋共振条件来探测电子在能量空间和物理空间中的分布函数的方法。基于这种多普勒频移共振的诊断能够通过改变视角、频率和磁场来改变共振在物理或能量空间中的位置，从而研究各种电子分布。对于在变化的磁场中观测的情况，例如在托卡马克中面上，对色散关系实解的共振条件的约束可以约束光学薄发射的物理位置。为了研究低杂波电流驱动过程中的高能电子，在PBX-M托卡马克上安装并运行了一种新的斜角电磁场诊断装置。它具有相对于托卡马克中面垂直33°的视角，接收秒…
Electron cyclotron emission (ECE) at an oblique angle to the magnetic field provides a means of probing the electron distribution function both in energy and physical space through changes in and constraints on the relativistic electron cyclotron resonance condition. Diagnostics based on this Doppler shifted resonance are able to study a variety of electron distributions through changes in the location of the resonance in physical or energy space accomplished by changes in the viewing angle and frequency, and the magnetic field. For the case of observation across a changing magnetic field, such as across the tokamak midplane, the constraint on the resonance condition for real solutions to the dispersion relation can constrain the physical location of optically thin emission. A new Oblique ECE diagnostic was installed and operated on the PBX-M tokamak for the study of energetic electrons during lower hybrid current drive. It has a view 33° with respect to perpendicular in the tokamak midplane, receives sec...
