A continuous source of cold atoms is the most crucial prerequisite for realizing continuous atom lasers. The high magnetic moment of Chromium (Cr) makes it an ideal candidate to be guided by a magnetic guide. The special electronic structure of Cr allows for a continuous loading scheme of ultracold atoms in to a magnetic trap [1], as well as into a magnetic guide. In this talk we report on our recent experiments on continuous loading of atoms into a 1m long magnetic guide. We achieved a launch velocity of atoms between 0m/s to 3m/s by the moving molasses scheme .The possible applications in atom lithography will also be discussed.
