for the COMPASS Collaboration A proposal to the CERN scientific committees
concerning COMPASS future plans is being prepared. A request for SPS muon beam
delivery in the medium term for precision measurements on the transverse and
longitudinal spin structure of the nucleon was submitted. The proposals to study
the Generalised Parton Distribution functions via measurements of Deeply Virtual
Compton Scattering and the Transverse Momentum Dependent distributions via
measurements of the Drell–Yan process are outlined
