7. http://totem.web.cern.ch/Totem/ Roman Pot Engineering Design Review CERN, 14 February 2006 M.Oriunno, CERN PH-TOT Deliverables from previous tasks : Roman pot stations installed and aligned, cooling plant installed, cables and patch panels electrically tested and connected Infrastructures : In addition to the permanent specified services, Power supply 220V/50Hz for test equipments, Internet connection Access requirements: Standard access mode to the tunnel, since no dangerous materials or tests are foreseen. Access granted to a team of ~4 people minimum plus tools per sub-system to be commissioned 1 st assumption -> The Roman Pot are vacuum equipments of the LSSs. They must be included in the planning of the vacuum commissioning of the LSS, namely: Sectorization valves, bake out, NEGs activation, pure gas filling if required. 2 nd assumption -> At the commissioning the pots are under secondary vacuum, but without the detectors. 1.Motors & controls commissioning 2.Cooling System Commissioning 3.Interlocks & Signals Commissioning 4.Detectors connectivity and cooling Commissioning of the Roman Pot (Discussed at the LHC Hardware Commissioning Working Group, 3 march 2005) https://edms.cern.ch/document/566502/1

9. http://totem.web.cern.ch/Totem/ Roman Pot Engineering Design Review CERN, 14 February 2006 M.Oriunno, CERN PH-TOT Tasks :Check the logic of the interlocks signals with the Control Room To be included in the interlock commissioning of the machine Crew : 1 Sub –system supervisor 1 technician in the tunnel 1 operator in the Control room Timing: ~ 4 hours for 1 crew FTE Remarks : Non need of the machine vacuum Interlocks & Signals Commissioning sequences

10. http://totem.web.cern.ch/Totem/ Roman Pot Engineering Design Review CERN, 14 February 2006 M.Oriunno, CERN PH-TOT Tasks : Electrical connection of a test assembly detector (warm system) Checking of:readout system low voltage bias voltage temperatures Crew : 1 Sub –system supervisor 1 technicians in the tunnel 1 technicians in the counting room Timing: 24 detector assemblies to check ~ 12 hours for 1 crew FTE Remarks : Non need of the machine vacuum Detectors connectivity
