The HERMES experiment, installed in the 27.5 GeV HERA lepton ring at DESY/Hamburg, is used to study the spin structure of the nucleon. To get information about the orbital angular momentum L{sub q} of quarks, exclusive DIS reactions are investigated. The HERMES Collaboration installed a new Recoil Detector to upgrade the existing spectrometer to improve the study of hard exclusive processes, detecting recoil protons with low momentum. Deeply Virtual Compton Scattering is the main process to be studied. The HERMES Recoil Detector consists of three subcomponents inside a superconducting magnet that provides a longitudinal superconducting magnetic field of 1 Tesla. The Recoil Detector was installed in January 2006 and commissioning started in February. First results from the detector will be presented.
