The plasma frequency has a particularly simple form that depends only on the electron density: n p = w p /2p = (1/2p)[4pn e e 2 /m e] 1/2 ~ 9 x 10 3 n e 1/2 , where the units are cgs units, and so the electron density is expressed in units of cm-3. This is the natural frequency of oscillation of a plasma, so any disturbance that provides energy ... …that their frequency equals the cyclotron frequency of the plasma ions—i.e., the rate at which the ions travel around the doughnut-shaped magnetic field of a cyclotron (q.v.). Approximately 600 kilowatts of radio-frequency energy were utilized to heat the plasma to roughly 23,000,000 K. Electron cyclotron maser radiation is emitted at the frequency at which electrons spiral around the local magnetic field lines (the cyclotron or Larmor frequency): (52.6) v L = q B 2 π m e c where q is the elemental charge, B is the magnetic field strength, m e is the electron mass, and c is the speed of light.

Some Notes on SI vs. cgs Units by Jason Harlow Last updated Feb. 8, 2011 by Jason Harlow. Introduction Within “The Metric System”, there are actually two separate self-consistent systems. One is the Systme International or SI system, which uses Metres, Kilograms and Seconds for length, mass and time. For A. Cyclotron A cyclotron has constant magnetic field magnitude and constant rf frequency. Beam energy is limited by relativistic effects, which destroy synchronization between particle orbits and rf fields. Therefore, the cyclotron is useful only for ion acceleration. The virtue of cyclotrons is that they generate a continuous train of beam ... …that their frequency equals the cyclotron frequency of the plasma ions—i.e., the rate at which the ions travel around the doughnut-shaped magnetic field of a cyclotron (q.v.).
