BEC started as a novel kind of Ioffe-Pritchard trap using ring-shaped coils rather than traditional Ioffe bars [1]. In this trap, we have demonstrated a new type of atom laser, which beats the flux limit of traditional weakly coupled atom lasers by about one order of magnitude [2].
Unfortunately, recently one of our magnetic field coils was destroyed due to earlier problems with the quality of the cooling water. Vasiliki and Premjith recently have converted the Ioffe trap into a QUIC trap without any changes to the coils themselves. We are now going to apply our adiabatic potentials to this system with view to finding a more convenient method of analysing phase fluctuations in elongated condensates.
