  1. ZDC DCS status Francesca Poggio Università degli Studi di Torino INFN, sezione di Torino

  2. ZDC detectors Beam pipes ZP ZN two sets of calorimeters on both sides of the interaction point • made in Torino and Cagliari • 2 hadronic “spaghetti calorimeters” • 1 for spectator neutrons (ZN) 1 for spectator protons (ZP) • placed at 116 m from the IP neutron ZDC proton ZDC • 2 forward electromagnetic calorimeters (ZEM), placed at 7.5 m from the interaction point

  4. ZDC DCS status HV and current should remain stable (apart from small correction due to light attenuation) no HV interlock is required at present we are starting the implementation of the DCS Project • for each PM we should write: • channel name • set voltage • maximum current • ramp UP • ramp DOWN • trip parameter • enable/disable power ON option • status • for each PM we should read: • channel name • set voltage • output voltage • output current • maximum current • ramp UP • ramp DOWN • trip parameter • enable/disable power ON option • status
