  1. Summary of Installation and ITF Workshop at SURF William Miller November 8th, 2018v2 Det#3 Det#1 Det#4 Det#2 https://indico.fnal.gov/event/18435 Summary of SURF- ITF and Installation Work Shop

  2. Changes in the Baseline Installation Plan North Cavern Central Cavern South Cavern Move from the baseline of building detector #1 and #2 in cavern #1 (North) to building Detector #1 in cavern # 1(North Cavern) and Detector #2 in cavern #3 (South Cavern) Use North and South Cavern for detector halls New Layout of Cryostat has the vertical cryogenic plumbing on the same side as the TCO: See next slide Need to reorganize some of the penetrations including the DSS shuttle beam All DSS penetrations reduced to 20cm diameter Summary of SURF- ITF and Installation Work Shop

  3. Cryogenic Penetrations reorganized DSS penetrations to be mirrored, all at 20cm diameter New drawings to be issued and approved by GTT Summary of SURF- ITF and Installation Work Shop

  4. New Layout of the top of the cryostat monorails ~20T bridge crane ~12T Cryogenics Mezzanine detector mezzanine cable trays to CUC The original mezzanine was increased in length to give us two additional barracks for electronics installation on top of the cryostat Summary of SURF- ITF and Installation Work Shop

  5. 3-D View to CUC N Summary of SURF- ITF and Installation Work Shop

  6. New Detector Electronics Mezzanine N 78 Detector Electronics Racks are located on the north side of the cryostat on an elevated mezzanine They have been elevated to free up space on the top of the detector to better organize and manage cable routing and access on the cryostat ~200KW of heat from the 78 electronics racks is dissipated into the cavern air Summary of SURF- ITF and Installation Work Shop

  7. Estimated Installation Sequence-FTE Overview • Increased CF underground occupancy to ~65 FTE/shift (80 is the CF Max), still need input from: • SURF • CUC/top of cryostat • Cryogenic • We are close to 144 FTE maximum underground It looks like the only tight time period is during the excavation of Cavern #3 Summary of SURF- ITF and Installation Work Shop

  8. CUC, DAQ & SP Detector Infrastructure N Once the majority of the Cold structure has been installed this opens up allows us to begin setting up the infrastructure for the cleanroom which includes cold boxes, tooling, assembly towers and rail systems ~6 months before assembly starts At the same time we get Beneficial Occupancy of Cavern #1 there is a time period of roughly 18-21 months to install the infrastructure for the CUC and install the DAQ Summary of SURF- ITF and Installation Work Shop

  9. Logistics Center and ITF With our new logistics manager, “Ladi” Ladislav Jakubec, our shipping and handling concept is starting to take shape. While we have a reasonable list of components for working out the Logistic Center and ITF we have not completed a requirements document yet to describe what is needed. The basic concept is: Logistic Center All DUNE materials are inventoried, staged, stored and shipped to the headframe from the Logistics Center Integration and Test Faculty Integration of the APA, PD and CE components would happen in ITF Possible installation of a single cold box to test APA production from the multiple factories The final cold test of APA pair is now done in the three vertical cold boxes underground Summary of SURF- ITF and Installation Work Shop

  10. Detector #1 SP Installation rate of 3 APA pairs and 2 CPA pairs/week Once the Cryostat is cleaned we are ready to begin installation The ~1 year installation period includes: • ~3 months for internal cryogenic piping, sub floor and the DSS system • 1 month ramp up and 1 month slow down periods for TPC components • 5 months of installation at the rate of 3 APA pairs/week Discussed the possibility of NOT deploying FC until at least ½ the detector is built This allows operation/monitoring of the installed electronics with the potential to replace after this burn-in period This works if it does no affect the overall installation time

  11. Schedule completes 3 APA pairs/week Summary of SURF- ITF and Installation Work Shop

  12. New APA Assembly Tower Improved Layout of Cleanroom N Egress Path to CUC Personnel SAS Clean Room TCO Materials SAS N Materials SAS Top View with roof framing Summary of SURF- ITF and Installation Work Shop

  13. CPA Assembly Frame APA Cable Tower-DRAFT Installation Assumptions 3 Cold Boxes APA Repair Frame APA Assembly Tower N APA Assembly Tower: 4 shifts per APA pair APA Shipping frame box is rotated into position on it’s end Bottom APA is mounted to Tower, PDs tested and repaired if needed Top APA is mounted to the Tower, PDs tested and repaired if needed Two APAs are now joined and rolled into clean room APA Cable Tower: 4 shifts per APA pair Dual Assembly frame is used to install cables and testing Cable trays, Cable management, Photogrammetry/Survey CPA Assembly frame: 3 shifts per CPA/FC Pair Uses shuttle beam crane to lift CPA components Re-located so CPA assembly does not affect access to the cold boxes Summary of SURF- ITF and Installation Work Shop

  14. CPA Assembly Frame New Assembly Tower-DRAFT Installation Assumptions 3 Cold Boxes N Three Cold boxes Draft Cold Box design, cold box function document being updated 8 shifts to cable, cool down, test, warm up Friday-Sunday the cryostat TCO is shielded with a mesh door that allows us to run noise studies on the installed section of the TPC Summary of SURF- ITF and Installation Work Shop

  15. Construction of Detector #3 • This is work in very preliminary and in progress, but we are trying to design the work done on Detector #1 so we have a minimal number of things to change for Detector #3: • Best location of stairs is in the north-east corner of the gap between modules connected to Detector #1 • Cold boxes would have to be relocated in front of TCO to make room for pumps on Detector #1 • APA Cable tower would move to under North Cavern Bridge • CPA assembly would stay in the same place • Material SAS would be on the North Cavern Bridge Summary of SURF- ITF and Installation Work Shop

  16. DUNE-Trial Assembly Work at Ash River APA Assembly Area at Ash River Since the Integration/Installation workshop last collaboration meeting there has been numerous changes to the installation cleanroom layout. We have not had a chance to adjust to these changes yet APA vertical cabling test stand will hopefully be up before Thanksgiving Area for construction of the APA tower has been cleared out and prepped at AR. Plan to have new design of APA tower for review by the end of November so we can get some cost estimates-Concept is the same a steel frame that holds the APA mounting rails with a temporary scaffold stairs and work platforms in the center Our optimistic goal is to be ready for an Integration/Assembly workshop at Ash River in March 2019 after the first two APA frames are sent in late February Critical to test assembly process as soon as possible Summary of SURF- ITF and Installation Work Shop

  17. Issues yet to resolve • APA Shipping Frame design • Single design or one for APA Factory to Logistics Center and to underground • Cleanliness in SAS and cleanroom • Where/when do you remove outer shell of APA Shipping Frame. How do you clean CPA boxes? Wrapped for delivery • Design of the shuttle beam/crane system and minimize the time it takes to make beam connections • Current manlifts only have a platform level of 12m. We need to get to ~14.5m to work on top of APAs, CPA and shuttle beam connections • Cold box design with opening doors, cryogenic system that allows us to work while cooling, Cold box cycle time ~3 days • Installation inside the cryostat- Deployment schedule, access equipment, removable floor design, closing the TCO, cryostat lighting, etc. Summary of SURF- ITF and Installation Work Shop
