Abstract

A novel mm-scale Ioffe-Pritchard trap is used to achieve Bose-Einstein condensation in 7Li. The trap employs free-standing copper coils integrated onto a direct-bond copper surface electrode structure. The trap achieves a radial magnetic gradient of 420 G/cm, an axial oscillation frequency of 50 Hz and a trap depth of 66 G with a 100 A drive current and 7 W total power dissipation.
