We report on the simultaneous transport of mixed quantum
degenerate gases of bosonic 87Rb and fermionic 40
K in a harmonic potential. The samples are transported over a
distance of to the geometric center of a
Ioffe-Pritchard type magnetic trap. This transport mechanism was
implemented by modification of the QUIC trap and is free of losses
and heating. It significantly extends the capabilities of this trap
design. We demonstrate a launching mechanism for quantum degenerate
samples and show that highly homogeneous magnetic fields can be
created in the center of the QUIC trap. The transport mechanism may
also be cascaded to cover even larger distances for interferometric
experiments with quantum degenerate samples.
