  1. Service Quarter Panel Status On behalf of many E. Anderssen LBNL

  2. First SQP Delivered to SR1 E. Anderssen LBNL

  3. Installed into Detector Package E. Anderssen LBNL

  4. SQP C34 Integration Begins • C34 is the first of 8 quarter panels to be integrated • Mechanical Mating of C34 went well • Lift Fixture validated • After mating with the BPSS, C34 passed all electrical connectivity tests • The first Heat Exchanger was connected at PP0 and Leak Checked on Friday • HX connection will continue for the next few days • Preparation for first connection of Type 0 cables to PP0 underway E. Anderssen LBNL

  5. Beam Pipe Load Transfer to BPSS complete • Bellows and Temporary supports installed at PP1 • Wires at PP0 installed and tensioned • Sensitivity study of adjustment resolution of PP0 adjustors complete E. Anderssen LBNL

  6. SQP Production Status • Recently added systems delayed delivery of C34 until now, but should not delay remaining panels • More work was added between loading Opto-Boards and Completion of an SQP • Component preparation and fabrication can be done in parallel and is now mostly complete • Components are added to installed opto-boards so must wait for this to be completed on each SQP • Opto-board loading is progressing fast • A34, the next load candidate will follow C34 on schedule—2wks after C34 • Remaining panels should follow at 1/wk thereafter to keep on schedule • This rate seems possible, but will likely involve long work-days and work on weekends to achieve E. Anderssen LBNL

  7. Opto-Board Heater • Decided to add Heater and Blanket system to SQP to address issues with Opto-Boards in early January • Heater strip introduced to every Opto-Board group to control temperature • Required installation and routing thru PP1 of new cables to power heaters • Additional Components to fabricate and integrate • First article Heater strips available in late Jan, full production lot now in hand—need to solder together • Blankets fabricated by hand from Cu-Kapton, all complete • Heater Cables to dress along SQP Backbone, thru PP1 and splice to Heater Strips • Testing to validate performance progressed in parallel with design to integrate additional services • Additional QA steps added to qualify Heaters • IR survey and additional electrical connectivity tests added to SQP assembly task list • Minimal impact to overall assembly—just more work E. Anderssen LBNL

  8. SQP Status—available on Wiki E. Anderssen LBNL

  9. Next Steps • A34 at SR1 8-March • Based on experience of completing C34 and A34, optimize the assembly order, and queue • Fit in PSQP opto-test after A34 complete/before C56 • Completion of SQP’s is opto-board driven, and the loading is going fast and well E. Anderssen LBNL
