Partially ferromagnetic electromagnet for trapping and cooling neutral atoms to quantum degeneracy
Abstract : We have developed a compact partially ferromagnetic electromagnet to produce a Ioffe-Pritchard trap for neutral atoms. Our structure permits strong magnetic confinement with low power consumption. Compared to the previous iron-core electromagnet, it allows for easy compensation of remnant fields and very high stability, along with cost-effective realization and compactness. We describe and characterize our apparatus and demonstrate trapping and cooling of Rb 87 atoms to quantum degeneracy. Pure Bose-Einstein condensates containing 10^6 atoms are routinely realized on a half-minute cycle. In addition we test the stability of the magnetic trap by producing atom lasers.
