We discuss the measurement of the electric field drift ($\overrightarrow{E}x\overrightarrow{B}$ velocity) and its spatial derivatives in a low temperature magnetized plasma by means of a suitably arranged multi-pin Langmuir probe. Results are presented relating the properties of the velocity field and its electrostatic fluctuations. In particular, we have measured components of the non-linear terms in the fluid magnetohydrodynamics equation.

多针朗缪尔探针，用于测量电场漂移及其空间导数

我们讨论电场漂移的测量（$\overrightarrow{E}X\overrightarrow{乙}$通过适当布置的多针Langmuir探针在低温磁化等离子体中获得最大速度）及其空间导数。给出了有关速度场及其静电起伏特性的结果。特别是，我们已经测量了流体磁流体动力学方程中非线性项的分量。
