Plans for installa,on Jim Stewart BNL July 18 2018
DUNE Far Detector layout � Bridge There is no rock pillar. Assembly work outside the cryostat occurs under the bridge. Detector Equipment is inserted Cryostat through a TCO Assembly area. 7/18/18 J Stewart BNL 2
Ini,al Installa,on Phases • The DUNE surface and CUC areas are available years before we gain access to the cryostat. • The DAQ is installed well before the detector installaMon starts. (Should be true for slow control also.) • Cryostat #2 foam and membrane are installed in parallel to detector #1 • The first 4 months aSer we gain access to the cryostat are spent seTng up the installaMon infrastructure. • The racks, cable trays, AC power, Rack cooling on the cryostat roof will be in place. • The detector support structure will be in place with the internal switchyard. • The installaMon cleanroom with all needed equipment are installed. 7/18/18 J Stewart BNL 3

DUNE Far Detector � Outline of Clean Room � ‘Dirty’ East � Toaster � Clean West Toaster & under Bridge � Divider Curtain � North Utility Corridor � Changing Room � Divider Curtain � around stairs � Exit Stairway � (dirty) � South Utility Corridor � 7/18/18 J Stewart BNL 6
Plan View of Detector #1 Setup � Under the bridge � • Access Underground is either using the stairs or using the manliS. • If the stairs are used then one needs to walk through the Air Lock Area. • Changing room for ~30 people per shiS 7 7/18/18 J Stewart BNL
APA Delivery � 1) Crated APA is positioned on Bridge, � Cave Crane moved into position � Equipment enters from the North driS • 2 APA with PD and CE boxes are in a crate. • The CE cables are not acached 2) Crate lifted & moved over SAS in East Toaster � Not much space between the bridge and the APA boxes The guard rails need removed and people need to be Med off 7/18/18 J Stewart BNL 8
APA are Rotated to Vertical in the Airlock � 3) APA Crate on SAS Floor � 4) Crated APA rotated to vertical position � 7/18/18 J Stewart BNL 9
DUNE Far Detector � Panel Components Staged in SAS & Clean Room � A cart on rails could be used to slide the APA into the cleanroom 10 7/18/18 J Stewart BNL
DUNE Far Detector � APA Handling � Vertical APA Crate placed in cart � The 2 APA Panels are fixed APA Panels moved to Fixture � together � � � A bridge crane will be mounted under the bridge to move equipment in the cleanroom 7/18/18 J Stewart BNL 11
APA-CE cabling • CE cables are routed through the APA side tubes in the cleanroom aSer the two APA are connected together. • A stairway work plaeorm “APA Assembly Tower” is used to work off of for the cabling and tesMng. 7/18/18 J Stewart BNL 12
Rail system for Inser,on into the cryostat • The yoke and a transfer beam are mounted while the APA are on the assembly fixture. • When cabling is done the APA are liSed onto the transport rails. • A crawler will push the APA along the rails 7/18/18 J Stewart BNL 13
DUNE Far Detector � APA Handling � 10) APA panel ready to install in Cryostat, moved to APA-side of TCO track � 7/18/18 J Stewart BNL 14
Debugging sta,on • Space is available next to the assembly staMon for debugging if needed. 7/18/18 J Stewart BNL 15
DSS and switchyard • A shucle system of beam inside the cryostat are used to transport the APA to to the correct row of I- Beams for deployment. • It is planned to stop the APA at an intermediate posiMon to allow tesMng for several shiSs. • Access will be with a scissor liS 7/18/18 J Stewart BNL 16
CE cabling and tes,ng • Cabling through the cryostat roof will take two shiSs. Two people will be on a scissor liS and two on the roof. 7/18/18 J Stewart BNL 17
Assembly Labor Assumptions Standard work week is considered to be four 10 hour days. Starting and ending at the headframe. The cage can carry 35 workers max, with 150 people underground per shift. This includes LBNF, SURF, Cryogenic construction, contractors as well so shift start times will have to be staggered. A standard work shift assumes ~70% efficiency • Ride underground, morning safety and assembly tasks meeting, morning coffee break (20 min)- 1 hour • Lunch break including time to get to lunch area- 1 hour • Afternoon coffee break (20 min), end of the day cleanup and ride to the surface- 1 hour This leaves us with a typical work day of ~3.5 hours in the morning and ~3.5 hours in the afternoon for each shift Scientific effort on off days needs negotiated.
APA Assembly Area APA Assembly Area: There are three work locations for the APAs in the cleanroom. The crew size is 6 FTE, 2 are crane operators • The APAs box is already in position in the cart and they are lifted into position using the under-bridge crane with 2 FTE in the scissor lift, 2 on the ground and 2 FTE in the stair/work platform • The APA CE and PD cabling, joining the two APAs together, cable tray installation, lifting the APA to DSS height, initial testing and cable management all take place over 3 shifts in this area
APA Test Area S Shuttle beam h u APA Test Area-Shuttle Beam : t t Still working on the testing scope in the l e shuttle area � B Expect several shifts based on APA e a estimates. m Curved rail for bringing APA into cryostat � Shuttle Beam with APA �
APA Top/Inside Cryostat Cable Area APA Top/Inside Cryostat Cable Area: There are two work locations for this task which is expected to take two shifts per APA pair. Most of the time: • A crew of 2 FTE are in a scissor lift inside the cryostat • 2 FTE are on the top if the cryostat pulling the cables up
Summary • An initial draft plan for the installation is available. • This plan is being iterated with the consortia to be sure there is consensus on the time an labor estimates. • It is understood that the start of the installation will go slow. • We need to discuss in a broader group the plan for testing. - Should we stop every so often to make the detector dark and shielded to measure noise? • The organization of effort between TC and the consortia is still being discussed.
