Plans for installa,on

DUNE Far Detector layout

Detector Cryostat Bridge Assembly area. There is no rock pillar. Assembly work outside the cryostat occurs under the bridge. Equipment is inserted through a TCO

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.

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

APA Delivery

1) Crated APA is positioned on Bridge, Cave Crane moved into position 2) Crate lifted & moved over SAS in East Toaster

Equipment enters from the North driS Not much space between the bridge and the APA boxes The guard rails need removed and people need to be Med off

• 2 APA with PD and CE

boxes are in a crate.

• The CE cables are not

acached

APA Handling

Vertical APA Crate placed in cart APA Panels moved to Fixture

• The 2 APA Panels are fixed

together

• A bridge crane will be mounted under the

bridge to move equipment in the cleanroom

7/18/18 J Stewart BNL

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

• ff of for the cabling and tesMng.

12 7/18/18 J Stewart BNL

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

Debugging sta,on

• Space is available next to the

assembly staMon for debugging if needed.

15 7/18/18 J Stewart BNL

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

16 7/18/18 J Stewart BNL

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.

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
 Shuttle beam

APA Test Area-Shuttle Beam: Still working on the testing scope in the shuttle area Expect several shifts based on APA estimates.

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.
