Shifts of the cyclotron mode frequencies, away from the single particle limit, are observed to be proportional to the measured E × B rotation frequency in a non-neutral ion plasma. These cylindrical ion plasmas consist of , , and ; with , and impurities. Laser cooling of the majority species enables temperature control over the range 10−5 < T < 10−2 eV, as well as determination of cyclotron mode frequencies from launched wave absorption. At moderately low temperatures, the m θ = 1 and m θ = 2 cyclotron frequency shifts are well described by cold fluid theory for an equilibrium square profile. However, for T < 10−3 eV, centrifugal mass separation can shift the mode frequency back towards the single particle limit.
