Brief Intro• General plan in the US is to set up multiple APA factories to
produce 150 APAs (enough for a 10kt DUNE module)- ½ the first module and ½ the second module
- with the other halves produced here in the UK
• PSL, Chicago, Yale - PSL is, of course, already a working assembly line
- I’ll talk about UChicago as a possible site for additional assembly lines and the next talk will introduce Yale
• In this talk- Photo tour of campus facilities
- A look at possible layouts of APA assembly lines
- Example of a past project and summary of local resources

APA Factory Layout Option #2• Modify the existing interior space to
be a “wiring lab”
• Extend length of lab and add a high, wide door exiting to high bay
• Clear advantages to working in this climate controlled, clean, well-lit space
• Leaves open high bay area just outside lab dedicated to shipping, receiving and prepping frames for wiring

Double Chooz Construction @ Chicago• Double Chooz muon tracking system was
constructed in these same spaces @ UC- 3 year construction project from 2008-2010.
- Built 130 4m x 1.6m scintillator strip modules now in use at DC, ICARUS, and ProtoDUNE.
- Project team: 1 faculty + 2 PDs + full-time technician + supporting engineer + ~6 undergraduates at any given time (30+ students throughout the project)

More Details on Local Resources• University of Chicago campus is 45 miles from Fermilab and 25
miles from Argonne National Lab
• Construction area is right on campus, adjacent to HEP group offices (faculty, postdocs, students)
• Full machine shop connected to high bay; also many professional machining companies in Chicago area
• Electrical shop connected to high bay mezzanine
• Several smaller side and local labs for test or prep work
• Strong mechanical engineering team (working closely now with PSL, experience designing SBND APAs)
• Lots of undergraduate students looking for research related work
