    "abstract": "We have realized a scheme for continuous loading of a magnetic trap (MT).\n^{52}Cr atoms are continuously captured and cooled in a magneto-optical trap\n(MOT). Optical pumping to a metastable state decouples atoms from the cooling\nlight. Due to their high magnetic moment (6 Bohr magnetons), low-field seeking\nmetastable atoms are trapped in the magnetic quadrupole field provided by the\nMOT. Limited by inelastic collisions between atoms in the MOT and in the MT, we\nload 10^8 metastable atoms at a rate of 10^8 atoms/s below 100 microkelvin into\nthe MT. After loading we can perform optical repumping to realize a MT of\nground state chromium atoms.",
