We report on our recent progress in the manipulation and cooling of a magnetically guided, high-flux beam of ⁸⁷Rb atoms. Typically, 7×10⁹0.3em0exatoms0.3em0exper0.3em0exsecond propagate in a magnetic guide providing a transverse gradient of 8000.3em0exG∕cm, with a temperature ~5500.3em0exμK, at an initial velocity of 900.3em0excm∕s. The atoms are subsequently slowed down to ~600.3em0excm∕s using an upward slope. The relatively high collision rate (50.3em0exs^-1) allows us to start forced evaporative cooling of the beam, leading to a reduction of the beam temperature by a factor of 4, and a tenfold increase of the on-axis phase-space density.
