Query: Loading chromium atoms in a magnetic guide   We have realized a magnetic guide for ultracold chromium atoms by
continuously loading atoms directly from a Zeeman slower into a horizontal
guide. We observe an atomic flux of $2 \cdot 10^7$ atoms/s and are able to
control the mean velocity of the guided atoms between 0 m/s and 3 m/s. We
present our experimental results on loading and controlling the mean velocity
of the guided atoms and discuss the experimental techniques that are used.
