First data from the HERMES Recoil Detector

The Hermes Collaboration has installed a new Recoil Detector surrounding the internal gas target to upgrade the existing spectrometer. It detects and identifies low energy protons at large angles originating from hard exclusive processes. These measurements will provide access to generalised parton distributions. The Recoil Detector consists of a silicon detector inside the beam pipe, a scintillating fibre tracker, and a photon detector. All three sub-detectors are located inside a superconducting solenoidal.
