Abstract :
A Forward Neutron Calorimeter (FNC) for ZEUS is being constructed to detect high energy neutrons produced in the proton direction in ep collisions at HERA. To investigate the feasibility of such studies, a small iron-scintillator sandwich calorimeter was placed on the zero degree line 102 m downstream of the main ZEUS detector. The calorimeter was calibrated by studying proton beam-gas interactions during the HERA acceleration cycle. The design and construction of the calorimeter are described and the results of the test studies presented.
