Nevertheless, we have checked that the broadening is not due to a thermal distribution of magnetron energies by deliberately sideband cooling with the amplifiers on (Tz = 5 K) before damping the axial energy to 230 mK; we found no change in the broadening.
Cavity Control of a Single-Electron Quantum Cyclotron:\\Measuring the Electron Magnetic Moment
Sideband cooling with the coherent distribution of axial states found during self-excitation would produce a coherent distribution of magnetron states with a width that could explain the broadening, but the electron is not self-excited during sideband cooling.

In , the authors hypothesize that the shift could have originated in an excitation of the magnetron motion because a typical shift could have been explained by a 10% increase of the magnetron radius.

Thus, the total thickness of the layer structure was either 200 nm, 230 nm or 290 nm. A pure SiO2 layer of 300 nm used as a reference was also deposited on p-type Si substrate by magnetron sputtering without substrate heating.
