Micromotion-Synchronized Pulsed Doppler Cooling of Trapped Ions
Alexander Kato, Andrei Nomerotski, Boris B. Blinov
We propose and demonstrate a new method for Doppler cooling trapped-ion crystals where the distribution of micromotion amplitudes may be large and uneven. The technique uses pulses…
Two-tone Doppler cooling of radial two-dimensional crystals in a radiofrequency ion trap
Alexander Kato, Apurva Goel, Raymond Lee +5
We study the Doppler-cooling of radial two-dimensional (2D) Coulomb crystals of trapped barium ions in a radiofrequency trap. Ions in radial 2D crystals experience micromotion of a…
Direct Observation of Ion Micromotion in a Linear Paul Trap
Liudmila A. Zhukas, Maverick J. Millican, Peter Svihra +2
In this paper, direct observation of micromotion for multiple ions in a laser-cooled trapped ion crystal is discussed along with a novel measurement technique for micromotion ampli…
Efficient sympathetic cooling in mixed barium and ytterbium ion chains
Tomasz P. Sakrejda, Liudmila Zhukas, Boris B. Blinov
We study sympathetic cooling of the radial ion motion in a linear RF trap in mixed barium-ytterbium chains. Barium ions are Doppler-cooled, while ytterbium ions are cooled through…
An Upper Bound on the Strongly Forbidden Magnetic Dipole Transition Moment in {Ba}
Spencer R. Williams, Anupriya Jayakumar, Matthew R. Hoffman +2
We report the results from our first-generation experiment to measure the magnetic-dipole transition moment (M1) between the and manifolds in Ba. Knowle…
Measurement of the branching fractions and lifetime of the level of Ba
Carolyn Auchter, Thomas W. Noel, Matthew R. Hoffman +2
We present a measurement of the branching fractions for decay from the long-lived level in \Ba. The branching fraction for decay into the ground state was fou…
