One-dimensional behavior of elongated Bose-Einstein condensates
P. Bouyer, J. H. Thywissen, F. Gerbier +4
We study the properties of elongated Bose-Einstein condensates. First, we show that the dimensions of the condensate after expansion differs from the 3D Thomas-Fermi regime. We als…
Using ion production to monitor the birth and death of a metastable helium Bose-Einstein condensate
S. Seidelin, O. Sirjean, J. Viana Gomes +3
We discuss observations of the ion flux from a cloud of trapped metastable helium atoms. Both Bose-Einstein condensates and thermal clouds were investigated. The ion flux is compar…
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…
