Continuous loading of a magnetic trap

We have realized a scheme for continuous loading of a magnetic trap (MT). ${}^{52}\mathrm{Cr}$ atoms are continuously captured and cooled in a magneto-optical trap (MOT). Optical pumping to a metastable state decouples atoms from the cooling light. Due to their high magnetic moment $\left(6\mathrm{}\hspace{0.5em}{\mu }_B\right),$ low-field seeking metastable atoms are trapped in the magnetic quadrupole field provided by the MOT. Limited by inelastic collisions between atoms in the MOT and in the MT, we load ${10}^8$ metastable atoms at a rate of ${10}^8$ atoms/s below $100\hspace{0.5em}\mu \mathrm{K}$ into the MT. Optical repumping after the loading allows us to realize a MT of ground-state chromium atoms.
