Abstract: A millimeter-scale Ioffe-Pritchard trap is used to achieve quantum degeneracy in Li-7. The trap employs freestanding 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.
