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 ! lm 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 uorescence. However, the images may no longer provide a linear measure of the mode axial velocity.
