Abstract
We have developed an iron-core electromagnet and used it to trap neutr al atoms. The magnetic field can be switched from a spherical quadrupo le configuration to a Ioffe configuration within 2 ms. We load 2 x 10( 7) Rb-87 atoms from a vapor into a Magneto-Optical Trap (MOT) and tran sfer them into the purely magnetic trap with an efficiency of 95%. A s trong radial compression is possible since we can generate quadrupole gradients up to 0.1 T/cm with an excitation current of 10 A (400 W of power consumption).
