The COMPASS experiment has been taking data since 2002. Its polarized target was upgraded during the 2005 CERN SPS shutdown. With the high acceptance magnet we obtained +56.0% and -53.0% deuteron polarization in {sup 6}LiD. In 2007 ammonia is used as a proton target which has a relaxation time of {approx}4000 h at 0.6 T.
