Velo Burn-in Working Schedule April 20th 2006

The Status and Milestones of the VeLo module Burn-in System

Milestones

Milestones achieved are listed in a weekly basis:

14th of Febraury-16th of March:

• Mechanical:
  • The square segments of the cooling block have lids soldered onto them. The 4mm copper pipes and square blocks acting as U turns for the coolant have been made.
  • Vacuum support structure arrived from KJN and has been assembled.
  • Still to be done:
    1. Add 3/8" fittings to the cooling block.
    2. Attach cooling block to the module frame.
    3. Module frame.
    4. Hybrid Support. Attached to the side opposite of the cooling block.
    5. Module frame platform.
    6. Weld Module frame platform and Chamber Lid modifications (attach heli coils).
    7. Vacuum Chamber Lid Carriage.
    8. Rail Platform for the Burn-in system (We can pot connectors in).
    9. Repeater Board Crate (only side panels and location on the Burn-in system)
    10. Thermal Camera Locator.
    11. Vacuum pump box.
    12. Clean Room module transfer jig.
• Vacuum:
  • Calibration factors for the Pennnig pressure gauge have been obtained allowing the voltage measured to be displayed as pressure.
• Cooling:
  • The order for Julabo was placed on the 3rd of March. The company expects to deliver on the 22nd of March.
• Electronics:
  • The first EzyLV board to power up that has been made by IBLS will be delivered today after the last 3 versions contained errors. John will populate it as soon as we get them.
  • Operated an electronic single hybrid. Having problems configuring the beetles but it has been verified that Command clock and the I2C commands arrive to the repeater board.
• Software:
  • Communication between the DIM server in the credit card PC and a client has been verified in Glasgow.
  • A linux partition was created for the DAQ PC. There still a number of issues still to be resolved.
  • Niko promised LHCb Online Gaudi by the 17th of March.
• Building 186:
  • Clean room gear has been delivered.
  • No nitrogen will be used in the cabinets or in the boxes housing the modules.

9th-14th of Febraury:

• Mechanical:
  • Ray has made two out of the five segments of the cooling block . (expect to finish by the end of the week. Next week will be the modification of the chamber lid)
  • Firm quotes on the vacuum chamber structure. Order within a day or two.
  
  
• Vacuum System:
  • The following has been ordered:
    • Two cryogenic fluid feedthroughs (three weeks leadtime).
    • One 50pin feedthrough (10 days leadtime).
    • Blanks for the feedthroughs (3 days leadtime).
    • Connections for the oil filter that is located between the rotary and turbo pump (3 days leadtime).
    All the vacuum connections for one chamber are accounted for.
  
  
• Cooling System:
  • The following has been ordered:
    • Two insulated hoses.
    • adapters so they can be connected to the cryogenic feedthroughs.
    • Teflon 3/8inch flexible tubing and swagelok connectors.
    All the cooling connections for one chamber are accounted for.
    
  
  
• Electronic System:
  • Schematics for the Rpt Ezy LV board are done and John has started on the layout.
  
  
• Software:
  • Packets from TELL1's Gibabit ethernet card have been read.
  
  
• Building 186:
  • The microscope to be used during the receiving inspection has been located.
