Doppler cooling thermometry of a multilevel ion in the presence of micromotion

T Sikorsky, Z Meir, N Akerman, R Ben-Shlomi, R Ozeri - Physical Review A, 2017 - APS
We study the time-dependent fluorescence of an initially hot, multilevel, single atomic ion
trapped in a radio-frequency Paul trap during Doppler cooling. We have developed an …
