The presence and variation of a local magnetic field in a plasma volume can be used for local control of the parameters of plasma created by energetic electrons. The local magnetic field magnitude translates to the strength of the effective barrier against the penetration of energetic (and thermal) electrons (and ions) into certain regions where plasma generation can be modified. In those regions, the electron distribution function (EDF) may be local while, in the rest of the plasma, the EDF is typically nonlocal. The degree of this control is demonstrated to depend on the magnitude of the magnetic field.

有效局部控制等离子体非局部电子分布函数的证据

等离子体体积中局部磁场的存在和变化可用于局部控制由高能电子产生的等离子体参数。局部磁场强度转化为有效屏障的强度，以防止高能（和热）电子（和离子）渗透到可以改变等离子体生成的某些区域。在这些区域中，电子分布函数 (EDF) 可能是局部的，而在等离子体的其余部分，EDF 通常是非局部的。这种控制的程度被证明取决于磁场的大小。
