    "abstract": "We have theoretically investigated 3D focusing of a launched cloud of cold\natoms using a pair of magnetic lens pulses (the alternate-gradient method).\nIndividual lenses focus radially and defocus axially or vice-versa. The\nperformance of the two possible pulse sequences are compared and found to be\nideal for loading both \u0027pancake\u0027 and \u0027sausage\u0027 shaped magnetic/optical\nmicrotraps. It is shown that focusing aberrations are considerably smaller for\ndouble-impulse magnetic lenses compared to single-impulse magnetic lenses. An\nanalysis of the clouds focused by double-impulse technique is presented.",
