Abstract
Bose-Einstein condensation has been achieved in a magnetic surface microtra p with 4 x 10(5) Rb-87 atoms. The strongly anisotropic trapping potential i s generated by a microstructure which consists of microfabricated linear co pper conductor of widths ranging from 3 to 30 mum. After loading a high num ber of atoms from a pulsed thermal source directly into a magneto-optical t rap the magnetically stored atoms are transferred into the microtrap by adi abatic transformation of the trapping potential. In the microtrap the atoms are cooled to condensation using forced rf-evaporation. The complete in va cuo trap design is compatible with ultrahigh vacuum below 2 x 10(-11) mbar.
