Bose-Einstein condensation of metastable helium: some experimental aspects
C. I. Westbrook, A. Robert, O. Sirjean +3
We describe our recent realization of BEC using metastable helium. All detection is done with a micruchannel plate which detects the metastables or ions coming from the trapped ato…
Atom laser divergence
Y. Le Coq, J. H. Thywissen, S. A. Rangwala +5
We measure the angular divergence of a quasi-continuous, rf-outcoupled, free-falling atom laser as a function of the outcoupling frequency. The data is compared to a Gaussian-beam…
Thermalization of magnetically trapped metastable helium
A. Browaeys, A. Robert, O. Sirjean +5
We have observed thermalization by elastic collisions of magnetically trapped metastable helium atoms. Our method directly samples the reconstruction of a thermal energy distributi…
Understanding the production of dual BEC with sympathetic cooling
G. Delannoy, S. G. Murdoch, V. Boyer +3
We show, both experimentally and theoretically, that sympathetic cooling of Rb atoms in the state by evaporatively cooled atoms in the state can…
