Extended Data Fig. 3: Calculated energy distribution after buffer gas cooling of the ion using the parameters from the experiment.

From: Buffer gas cooling of a trapped ion to the quantum regime

Extended Data Fig. 3

The frequency of average secular kinetic energies is shown and fitted with a thermal distribution for a harmonic oscillator with a temperature of \({T}_{\sec }^{\perp }=38.2\) μK. No observable deviation from the thermal distribution is found. The results shown are from 300 simulation runs. In these simulations, the secular kinetic energy of the ion was obtained by filtering out energy contributions with a frequency higher than half the trap drive frequency, \({\varOmega }_{{\rm{rf}}}/2\), as explained in ref. 26.
