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…

Ionization rates in a Bose-Einstein condensate of metastable Helium
O. Sirjean, S. Seidelin, J. Viana Gomes +4
We have studied ionizing collisions in a BEC of He*. Measurements of the ion production rate combined with measurements of the density and number of atoms for the same sample allow…
