Abstract

We describe a technique and present results for imaging the modes of a laser-cooled plasma of 9Be+ ions in a Penning trap. The modes are excited by sinusoidally time-varying potentials applied to the trap electrodes. They are imaged by changes in the ion resonance fluorescence produced by Doppler shifts from the coherent ion velocities of the mode. For the geometry and conditions of this experiment, the mode frequencies and eigenfunctions have been calculated analytically. A comparison between theory and experiment for some of the azimuthally symmetric modes shows good agreement.

  21. Here ωlm is the mode frequency in a frame rotating with the plasma. For the m = 0 modes discussed here this distinction is not necessary because their frequency is the same in either the laboratory or rotating frame.
  22. Information on the mode eigenfunction can be obtained from the side-view images even when there is a change in the phase-averaged ion fluorescence. However, the images may no longer provide a linear measure of the mode axial velocity.

Here ωlm is the mode frequency in a frame rotating with the plasma. For the m = 0 modes discussed here this distinction is not necessary because their frequency is the same in either the laboratory or rotating frame.

Information on the mode eigenfunction can be obtained from the side-view images even when there is a change in the phase-averaged ion fluorescence. However, the images may no longer provide a linear measure of the mode axial velocity.

Plots of the frequencies of several magnetized plasma modes as a function of rotation frequency for Ω/2π=7.608 MHz and ωz /2π=1.13 MHz. The solid lines are the theoretical predictions and the symbols are experimental measurements. Only the highest frequency (9, 0) plasma mode and the second highest frequency (8, 0) plasma mode are plotted.

The ion cloud dimensions are 2z 0 = 0.76 mm and 2r 0 = 0.24 mm, and the density n 0 = 2.70 × 109 cm-3. Comparison of the amplitude (b) and phase (c) extracted from the (2,0) mode in (a) with the predictions of linear theory. The theory predictions are on the right. [Media 1]

(a) Movie of sideview image data obtained on a plasma with ωr /2π= 638 kHz while driving with an even drive at 1.619 MHz. At this rotation frequency there is a crossing of the (2,0) mode and an (8,0) mode with a radial node.
