A key innovation of this setup is a two dimensional magneto-optical trap deflector located after a Zeeman slower. We find a loading rate of 6x10^9/s whereas the lifetime of the magnetically trapped atoms in the 3P2 state is 54s.","authors_text":"B. Fang, C.C. Kwong, D. Wilkowski, E. Hajiyev, F. Leroux, K.
