• Fermilab
• Slides taken from presentations by Hans Hoffmann
  and Werner Jank

CERN/CMS visit

• Attended meetings as part of CMS/CPT week.
• Tier0 planning, DQM, CCAR
• CMS is planning to have a center of activity on
  the Meyrin site in addition to the operations
  centre at Point 5.
• Space at Point 5 is limited and the Control Room
  is not large enough for all activities.
• The Meyrin centre is known as CCAR though this
  name will change.
• At this moment, there is no space at CERN
  assigned to this centre.
• There is a proposal to use a space that is
  currently occupied by the print shop and the mail
  room. This space belongs to the IT division but
  may be made available to CMS - negotiations
  underway. However, funds are not yet secure.
• Their space planning combines remote operations
  and other activities.
• They would like to work together with us on
  planning for remote operations.
• We met with Hans Hoffmann, Werner Jank and Sergio
  Cittolin to discuss our plans for LHC_at_FNAL.
• They will try to help us with security issues if
  we need it.
• We visited Point 5, the control room building and
  the CMS hall.

CCAR Basic concept

• Allow operations team to work effectively
  together!
• Facilitate communication of all kinds
• Technical communications
• Point 5
• LHC control room
• Tier-0
• CAF
• Outside facilities (Tier-1s, Tier-2s)
• People communications
• Between operators
• Subdetectors
• Calibration / alignment
• express line(s)
• (prompt) analysis groups
• Physics community
• Regular (daily/weekly) updates
• Become Centre of Operations
