COMPASS is a fixed target experiment at CERN using high energy muon and hadron beams to study the nucleon spin structure and hadron spectroscopy. During its first phase COMPASS achieved the world most direct and precise measurement of the gluon contribution to the nucleon spin. A second research programme started in 2012 and is now close to completion, devoted to the 3-dimensional characterization of the nucleon structure. An addendum to the COMPASS-II proposal was approved in 2018 by the CERN Research Board, for additional deep inelastic scattering (DIS) measurements using a transversely polarised deuteron target in 2021.
The LIP group joined COMPASS in 2003 and since then it has been involved in the main analyses of the Collaboration. The group has the sole responsibility for the Detector Control System (DCS), an area where it has a recognized unique expertise. The LIP group is also strongly involved in the preparation of a new CERN experiment, using the same beam line and parts of the COMPASS spectrometer, to address important quantum chromodynamics (QCD) topics.
