W&M scope of work
- APA shipping frames
& hardware
– Coordinating with the Liverpool group (Peter Sutcliffe et al.) – Liaison PSL and SURF/ SDSD engineering on design integration – Initial prototype for APA pairing tests at AR (ASAP; CY 2019) – Trial runs at SURF (cage available August ‘20) – Production for US factories
- APA U/V frame boards
– Outfjtting facility – Board production – Cleaning/baking – Gluing tooth boards – Cleaning – QC & packaging – Shipping to factories –
Shipping frame use cases
- Factory packaging and prep for shipment [SBND pix]
- Getting to SD
– “Truck, ship, truck” or just “truck”
- Acceptance testing, long term storage at SDWF (warehouse)
- Transport to the head frame, slinging below cage [slide]
- Shafu transport; removal from shafu; transport to cavern
- Pre-testing and staging in cavern [slide]
- Into the SAS and clean room for mating/instrumenting
[slide]
- Return to the surface, warehouse, disposal/return shipping

- Overview
- Description of the use cases with current
installation model
- Specifjcations derived from the use cases
Drafu for comment – posted last week
Current design
Structural shipping frame welded steel construction
Concept based on SBND experience in UK
- DUNE crate concept
similar to SBND but with 2 APAs on sides
- Protective panels
- Coil spring dampening
- Structural frame
- Instrumentation
- Removable side frames
- Heat sealed bag
- Anchored to a pallet
- Tarping
- [UK version gets walls]
Shock isolators (coil springs) at 4 locations per APA
Loading onto shafu based on SURF experience
- We will work with SDSD to design a
Zimmerman (Zimmer) cart (their scope)
– Surface rail system – Factorizes rigging & frame functions – Includes wheels for movement in the drifu and for on/off loading – Include mount points for shafu guides timbers – Include anchor points for cables to bottom of cage and horizontal tugger – Underground truck provided
- Tiis concept makes the
slung-load operation consistent with standard SURF practices
Upper connection is base of cage (hoist acts as the upper winch)
Stages in cavern: testing, short-term storage, PSs, pairing
Hall: Tes;ng in a clean hut & storage (up to 12 APAs) SAS PD, ma;ng in clean room
In the SAS/clean room
- Tie frame/vertical cart is rolled into the SAS
- It is cleaned
- PDs installed with protection panels in place
- Need to lifu APAs out of the shipping frame and onto the APA
assembly frame
– pre-lifu to relieve tension, remove springs, move to tower
Shipping frame production model
Model for pre-proposal
- APA crate production in industry with W&M
coordination of the production
- QA/QC provided by W&M lead technician (8 hr per
frame)
- Tie basis of the cost estimate (c.f. DUNE-
docdb-10683) is benchmarked on a conceptual crate design, and the cost per crate is derived from component costs and production labor estimates in the UK. (Same vendor as SBND)
- Shipping costs for the crates are assumed to be
included the APA wiring site budgets.
- Assume to be single usage because APA production
is signifjcantly ahead of installation. Model for the full proposal
- Pallets produced by crating manufacturer in Port of
Norfolk area
– Staged production to match need at factories – Alternative is in-house production – QA/QC provided by W&M lead technician (1 hr per pallet)
- Welded central frame produced in fab shop
– Can put 4 per fmat bed – Staged production to match need at factories – QA/QC provided by W&M lead technician (8 hr per frame)
- Side frames made from 80:20; produced on campus
– Undergrad effort with GS/PD/PI supervision
- Clear plastic protective panels produced at local water-jet
cutter and hardware added at W&M
- Cable springs & sensors purchased at W&M
- Bagging material and heat sealers provided at factories.
- W&M pays shipping to factories
– Pallets and structural frames direct from vendor – Other parts from W&M crated kits – Included smaller crates and coordination
- Assume that half of the Mod 1 crates get reused for Mod 2
Assumes part-;me PI and/or postdoc coordina;on Work done by ;me first Mod 1 crates returned to factories
U/V boards
- Procure boards
- Board QC
- Clean/bake
- Epoxy on tooth strips
- Cure in fjxtures w/ venting
- QC of glued board
- Bag cleaned fjnal parts
Geometry boards: (foot & side): 60 min per board Head boards: add 30 or 40 min more for pins
- Incoming inspection, cleaning,
prep for processing: 10
- Tooth strip cutting, handling,
- rganizing for production: 10
- Attachment of tooth strips,
removal of excess epoxy: 20

inventory, fjnal inspection, package for storage or shipping: 10
- U:
– 20 head – 10 foot – 42 side
- V:
– 20 head – 10 foot – 42 side
- Tiat’s 144 per APA
– 21,888 boards total
- 4 years of production
– Average 22 per shifu
- Plan on infrastructure for ~2x
– UG effort bump in summers
Costing model
- Effort and M&S based on PSL experience (BOE docdb-10689)
– Labor includes: incoming inspection, cleaning, prep for processing, pin insertion, tooth strip cutting, solder pad masking, epoxying tooth strips, dimensional checks, excess epoxy removal, spot cleaning, fjnal inspection, and packing for storage/shipping
- Tie board production labor model at W&M assumes:
– Half of work completed by undergrads
- We assumes happens at 50% efficiency WRT technician in pre-proposal
– *evolve to 67% in consistent fjnal model with other sites
- 82.0* (85.4*) hours for U (V) boards per APA
- Students are costed at $12.50/hour (FICA in summers); 8 students averaged over year
– 10hr/wk in term, 40hr/wk summers
– Technician effort for remainder
- 41.0 (42.7) hours per APA
- Lead tech + term technical staff within instrumentation shop (2 FTE)
- Costed as recharge personal at $20/hour (i.e. fully loaded)
– Postdoc and grad student coordination of inventories/QA/tracking/shipping
- Professional faculty collaboration possible too
- Base grant supported
- Purchasing
– Postdoc + PIs
Facilities board production
- Clean room
– 24’ x 36’ lab – 20’ x 20’ class 100,000 clean room
- Sofu wall, tiled roof
– 2 vented workstations; single basin wet lab – Ultrasound cleaner – Space used for cleaning, baking, gluing, curing
- Chemical prep room across hall
– Outgas any surplus epoxy and clean up materials
- Tiree 24’ x 12’ labs across hall
– Shelving on both long walls – Vented workstation; single basin wet lab – Space used for storage, inspection, packaging – Vacuum + inert purge heat sealer (up to 36” capacity)
Outfjtting needs
- Fixtures – 44 units [slide]
- Precision scale and gluing stuff [slide]
- Washing stations
- Ovens
- Curing cabinets with venting
- Clean-ish room
- Inspection equipment [slide]
- Press
- Data entry PCs or tablets
- Vacuum/purge bag sealer
- Lots of shelves, googles, gloves, and kimwipes!
- Pre-proposal budget was a WAG
R&D opportunities – epoxy
- Current epoxy process is based on hand
application and spreading
– Nice video from PSL
– https://youtu.be/xiZBX5cq46c
- Can automate that with a
glue machine
– Locally developed engine for a 3D collagen printer
- Based on pipetting head with
fjne threaded stage
- Temperature controlled enclosure
- Open source g based code
– Use our pneumatic dispenser epoxy machine based on to understand fmuid mechanics (optimize needle)
- Can use barrel of pre-mix or dual pack with static mixer
– Defjne feed rate, tip diameter (1.5mm slot), movement speed to make a uniform continuous bead at reasonable pressure – Hardware is about $3k – Effort is in tuning the movement/feed/start+stop
- Stock parts
- Tech, 2 UG, and prof faculty
R&D opportunities – inspection
- Current is based on 2D profjle projector
– Manual process is somewhat time consuming even for an experienced tech – e.g. Mitutoyo 172-810-10A Profjle Projector – Semi automated system is $10k
- Would like to evolve to 3D to measure
fmatness and to measure
– Measurements of the machined edges – Looking for better than the 0.1mm tolerances – Can automate w/ CNC 3D vision machine ($40k) – Can automate with 3D scanner ($24k)
- Effort to interpret the scanner’s solid model output
- PSL investigating; good enough resolution?
- Good enough resolution at reasonable price?
– Could make hybrid a laser based z system with x-y based
- n standard 2D steppers and
R&D opportunities – prep/curing/cleaning
- Need to invest in sufficient units
units to meet capacity
- 40 jigs (can run 2-shifus in summers)
- Rack system with jigs vertical to improve
packing fraction
- Move to better substrate than tefmon
- Large oven/wash
- Chop saw and fjxtures for cutting strips
- Develop costing over next two weeks
