University of Chicago as an APA Factory Site

APA Workshop @ DaresburyFebruary 5, 2018

David Schmitz, Ed Blucher, Ben StillwellUniversity of Chicago

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
