Sub-milliKelvin spatial thermometry of a single Doppler cooled ion in a Paul trap

S. Knünz, M. Herrmann, V. Batteiger +3

We report on observations of thermal motion of a single, Doppler-cooled ion along the axis of a linear radio-frequency quadrupole trap. We show that for a harmonic potential the th…
