  1. TCC2/TDC2 LS1 Consolidation Plans EATM 09/10/2012 http://cern.ch/tcc2tdc2WG On behalf of the TDC2/TCC2 WG team

  2. Our plan for LS1 • Electricity • LV cabinet replacement • Groundloop upgrade • Renew Lights above XTAX and Targets • Implementsafetylighting • Re-route cabling in TDC2 and exchange cableswith PVC • Secondarybeamlines • Shielding modification • Survey of all beamlines • XTAX table second repair and upgrade • Collimators and targets • Monitor replacement • Mobile shieldingmotor exchange • TCSCexchange • Safety system upgrade according to safety file • Cooling and Ventilation • Controls Upgrade • Exchange of valves on Demin.& Chilledwater circuits • Chilled water pipe replacement (BA80/TCC2) • Vacuum • Damaged vacuum chambers & bellows replacement • Exchange and add ion pumps • Beam line protection system if no design change • Beam monitors • Magnets • Cooling flexibles replacement • Coolingpanoplyremovalfromcritical areas • Magnet support upgrade • Civil Engineering • Make roof and floor water tight as much as possible • Getrid of PVC tubes (drain network) • Corrective and preventive maintenance of drain network

  3. Planning: assomptions & contraints • Assumptions • T0: beam off: Feb 11th 2013. • Tf : restart of NA physics targeted for beginning of November 2014. • Constraints • RP requests 6 months cool down before short stay in TDC2/TCC2 (work preparation) and another 6 months cool down before longer intervention (work execution). • Dusty or tough activities (CE, new cable trays, water circuits) prior to new equipment installation. • Some co-activities are impossible (hot work, crane dependent, space consuming). • Hot work should be carried out at the very end of the access period. • Some groups (EN-CV and EN-EL) can start studies as of March 2014. Real work in the areas only after July 14. • Tf : 1 week contingency and 2 weeks for starting-up before restart of NA physics.

  4. Planning: option 1 • Postpone NA physics restart by another 3 months

  5. Planning: option 2 • Give priority to NA physics Proton and ion run

  6. Cablingrequests • New Radmon system • Heatingcollars for TE-VSC • New ion pumps • Targets ? • Makeyour DIC requests as soonas possible
