  • Fabrication and Assembly of the IDS
  • Critical Lift
  • PXL Platform
  • PXL air cooling
  • Other Tasks
fabrication and assembly of the ids
Fabrication and Assembly of the IDS
  • Assumption: Everything from other sub groups delivered on time
  • IDS carbon fiber transition cones may not be replaced this year so no deflection test will be performed on the IDS
  • Assembly sequence document exists and will be revised to incorporate assembly procedure and safety requirements
  • Assembly area required ~ 11m x 3m
  • Assembly area of the IDS will be same as the initial lift point for the critical lift
critical lift
Critical Lift
  • Scheduled for September 4, 2012
  • Critical lift milestones:
      • Load Testing, Hand Calculations and Certification for parts – May 31, 2012
      • Deflection Test Report – Done
      • Critical Lift Procedure and Layout – May 31, 2012
      • Submission of paperwork – June 15, 2012
      • Critical Lift Approval – July 31, 2012
  • Load Testing Status and Plan: Drawings of end plates to be supplied by Eric A. John S will proceed with the design of load testing parts.
  • Assembly weight that will be lifted during the critical lift is 425 pounds.
  • Everything below the crane hook has to be load tested and certified to 200% of the intended lift load except spreader bar that will be tested to 125%.
pxl platform
PXL Platform
  • Pre installation dry run on platform installation and use should be performed around end of May before detector roll out.
  • Design freeze date: March 31, 2012
  • Reviewed document with PXL group, minor design modifications required.
  • Safety requirements for platform:
    • PXL platform and ladders used to access platform should meet OSHA requirements (1910 Subpart D for Walking-Working Surfaces)
  • Platform design should be shown to the BNL machine shop. If they think they won’t be able to meet delivery deadline then it should be outsourced to a vendor.
  • Platform expected delivery date May 20th
pxl air cooling
PXL air cooling
  • PXL air cooling requirements:
    • 750 CFM with more than 10 inches of water pressure drop.
    • Regulate the temperature to 1-2 deg C
  • Existing IFC air system design to be copied
  • Requirements review ~ March 28
  • Design and manufacturing contract for the system will be issued to an outside vendor. (~ April 15)
  • Expected delivery date will be August 15, 2012.
