Fabrication Progress (Good News)

• Fabrication of EMCAL support structure at Fravit
  was completed in first week of February
• Top and bottom outriggers welded at Fravit
• Support fork material is available at CERN.
  Machining should be completed before end of March

15
Shipping to CERN (Bad News)

• Shipping company was behind schedule in getting
  all shipping documents approved
• All documents were approved to go through Mt
  Blanc tunnel on 2 March
• Mt Blanc tunnel was closed to all traffic due to
  rock slide on 3 March
• Tunnel was opened to normal traffic 10 March
• All special traffic not allowed until full repair
  is complete (could be several months)
• Applied for permits to change route to Frejus
• Juggling assembly schedule at CERN to minimize
  impact.

16
Remaining Tasks at CERN

• Weld support forks
• Align and connect the two half frames
• Load test
• Install SM rails
• Install EMCal services
• Ready for transfer to cavern
• Once the CalFrame is at CERN, we need 8 weeks to
  get ready for installtion inside L3

CalFrame Installation Fixture

• Installation fixture will be used for load test,
  assembly and installation

EMCal Services on the CalFrame

• Design of service is complete
• Fabrication of cable tray started
• All cables and connectors ordered and ready for
  assembly
• Water cooling components are on order
• CERN techs will assemble cable trays and low
  voltage cables
• EMCal techs will make up and install all other
  cables and cooling water tubes.

Other Engineering Development

• Prototype SM crate fabrication is complete
• Goal is to be ready to perform a dummy SM
  insertion test ( full weight) before the end of
  the summer 07
• 1. CERN has steel block that could be
  modified as SM dummy weight
• 2. Design of platform to support SM
  insertion tooling has started
