Sumario:The COMPASS collaboration has expressed the interest for pursuing an experiment dedicated to the measurement of the Generalized Parton Distributions (GPD). The GPDs can be accessed through the reactions of Deeply Virtual Compton Scattering and Hard Exclusive Meson Production. The experiment will use the existing COMPASS spectrometer with a new target, a new recoil detector and an extended calorimetry. Simulations for dierent models have been performed and the beam charge asymmetry accessible at COMPASS has a great sensitivity to the GPD models. A prototype of recoil detector was tested and shows a timing resolution slightly above the required precision.
