## NOνA

- Simple comparison to baseline detector
- Installation Numbers
- Liquid delivery system
- Problems  associated with longer modules
- Conclusion

## SimpleInstallation Comparison

- Basically just number of movements, distance covered and crane speed equals the time it takes to complete detector
- Baseline had 144,000 pieces (9000 stacks)
- All Scintillator has 28,000 pieces
- Peak Crew size Baseline Det. 	-41 FTE’s
- Peak Crew size All Scintillator -38 FTE’s

## SimpleScintillator Comparison

- Gallons of  mineral oil
- Baseline Detector     2.1M gallons - 6.8 kilotons
- All Scintillator Det.  7.1M gallons - 23.1 kilotons
- Trucks of Oil
- Baseline Detector      2.2/week-325 total
- All Scintillator Det.   2.2/day   -1100 total
- Trucking cost
- Baseline Detector      $1.08M
- All Scintillator Det.   $3.66M
- All Oil and Shipping costs based on last fall numbers!

## Simplify Design

- The installation estimate is based on a combination of Stan’s concept and Ken Heller’s self supporting design
- Combined concept would be a simple steel support structure that would allow access to the lower end of each module.
- Every module only gets moved once right from shipping container to detector face

## A Self Supporting Structure

**Modules at alternating at 45****o**

**Sealed bottoms**

## Modified Self Supporting

- Removable
- Work platform

- Removable work platform is strong enough to support shipping containers of modules so the crane movement is short

## Installation Numbers

- Plane is 17.5m x 17.5m containing 14 modules
- 2000 planes with alternating views
- Total of 28,000 modules
- Each module is taken straight from shipping container right onto detector face
- 2 overhead cranes one for unloading trucks, one with rotating vacuum lifting fixture

## Installation numbers

- Put module in place every 8 minutes
- 2 hours for each plane
- 1 hour/plane to survey and spray light layer of glue if needed
- Could easily build 5 planes/day with two 10 hour shifts.
- Installation 2 years (Baseline 4.3)

## Crew Size-Very Conservative #’s

- Receiving Team
- 1 module truck, 2 oil trucks, 1 misc. shipment per day this is easily handled by crew  3 on day shift. Also keep module crates in position on work platform
- Module installation team
- Modules are long but light, team of 3 FTE/shift. One for crane operator, two module locators
- Survey/Glue Team
- Team of 3 FTE/shift to survey modules and glue if needed
- Scintillator Oil Mix/Test Team
- Baseline detector had 4- Double team to 8
- QA team
- Baseline was 4-APD boxes double so team size to 8
- Support Staff
- Same size as baseline 7
- Baseline total was 41 FTE-4.3 years
- All Scintillator Detector 38 FTE-2 years

## Scintillator Delivery System

- 14,200 gallons/day to be mixed! Inline mixing system design would help
- Fill rate of roughly 15 gal./min. this is 3 times the rate  for the MACRO Detector
- Bigger mixing tanks? Or more of them?
- Must fill multiple modules at once, moving manifold system to deliver oil
- Delivery/Mixing system needs some R&D for both detectors

## Module Factory’s

- Baseline 12 modules/shift/factory 3.5 FTE
- Scale up to 14 modules/shift/factory by adding 1⁄2 FTE
- Need 2000 shifts- 200+ shifts/year
- If you run 2 shifts/day
- Need roughly 5 factories to complete modules in 2 years to match installation

##  LONG Module Trucks

- Modules will not fit on a standard truck a special permit will be needed. As long as you need a permit for length, you can add width for no extra cost up to 110”
- Quotes (Thursday) got estimate is $2/mile compared to $1.50/mile
- If module keep narrow can get about 96 modules on a truck load
- Four Shipping boxes per load- 60 ft long by 4 ft tall by 4 1⁄2 ft wide

## Conclusions

- Needs lots more work but design is simple, likely to cut more off crew size
- Scintillator mixing/testing system needs serious design work
- Access issues with diagonal detector
- Glue/not glue modules
- Between 1⁄2 size building and 1⁄2 installation time overall schedule is much faster
