摘要
In trapped plasmas, electric fields and collective effects shift the cyclotron mode frequencies away from the "bare" cyclotron frequency for each species s. Here, these shifts are measured on a set of cyclotron modes (m = 0, 1, and 2) with cos(m theta) azimuthal dependence in near rigid-rotor multi-species ion plasmas. We observe that these frequency shifts are dependent on the plasma density, through the E x B rotation frequency f(E), and on the "local" charge concentration delta(s) of species s, in close agreement with theory.
