    "abstract": "We present a robust continuous optical loading scheme for a Ioffe-Pritchard\n(IP) type magnetic trap. Atoms are cooled and trapped in a modified\nmagneto-optical trap (MOT) consisting of a conventional 2D-MOT in radial\ndirection and an axial molasses. The radial magnetic field gradient needed for\nthe operation of the 2D-MOT is provided by the IP trap. A small axial curvature\nand offset field provide magnetic confinement and suppress spin-flip losses in\nthe center of the magnetic trap without altering the performance of the 2D-MOT.\nContinuous loading of atoms into the IP trap is provided by radiative leakage\nfrom the MOT to a metastable level which is magnetically trapped and decoupled\nfrom the MOT light. We are able to accumulate 30 times more atoms in the\nmagnetic trap than in the MOT. The absolute number of $2\\times 10^8$~atoms is\nlimited by inelastic collisions. A model based on rate equations shows good\nagreement with our data. Our scheme can also be applied to other atoms with\nsimilar level structure like alkaline earth metals.",
