Number-Resolved Detection of Dark Ions in Coulomb Crystals
Fabian Schmid, Johannes Weitenberg, Jorge Moreno +3
While it is straightforward to count laser-cooled trapped ions by fluorescence imaging, detecting the number of dark ions embedded and sympathetically cooled in a mixed ion crystal…
Motional resonances of three-dimensional dual-species Coulomb crystals
Byoung-moo Ann, Fabian Schmid, Jonas Krause +3
We investigate the motional resonances of dual-species Coulomb crystals comprised of Be and Mg ions held in a 4-rod linear Paul trap. Our experimental data and s…
Simple phase noise measurement scheme for cavity-stabilized laser systems
Fabian Schmid, Johannes Weitenberg, Theodor W. Hänsch +2
We describe a simple method for measuring the residual fast phase noise of a cavity-stabilized laser using the cavity as a reference. The method is based on generating a beat note…
Simultaneous dual-species laser cooling using an optical frequency comb
D. Buhin, D. Kovacic, F. Schmid +4
We demonstrate 1D simultaneous laser cooling of Rb and Rb atoms using an optical frequency comb. By adjusting the pulse repetition frequency and the offset frequency,…
Consistent description of UCN transport properties
S. Wlokka, P. Fierlinger, A. Frei +6
We have investigated the diffuse reflection probabilities of Replica guides for ultra-cold neutrons (UCN) using the so-called helium method. For the first time we could establish a…
