Description
An overview of recent COMPASS (NA58/SPS) results on the determination of
longitudinal polarized quark distributions is given.
The results were obtained in inclusive and semi-inclusive deep-inelastic
scattering of a 160 GeV polarized muon beam off a large polarized $^6$LiD
target. The covered kinematics range is $0.004<x<0.7$ and $1< Q2 < 100$
(GeV/$c)2$. The presented data were collected by COMPASS in the years
2002--2004. A projection of the statistical precision for the data
collected on deuterons from the same $^6$LiD target in 2006 and on
protons from NH$_3$ target in 2007 is presented.
