Proto DUNE 2 Installation Steps William Miller University

Proto. DUNE 2 Installation Steps William Miller University of Minnesota 1/8/2020 Proto. DUNE 2 Installation 1

Rough Estimated Proto. DUNE 2 Schedule • CPA assembly frame is being picked up January 13 th. We are still on schedule to have the assembly frame installed by the end of January 1/8/2020 Proto. DUNE 2 Installation 2

Many Open Questions – Decommissioning/Installation What happens to Proto. DUNE? • 7 APA’s and only one shipping box are we saving them all? • Photon Detectors and cables? • What needs to be saved and what needs to be purged/recycled? • Can we just leave the roof open in the “cleanroom” if we are just removing everything? • What kind of area can we use for putting the old TPC components • TPC cables? Electronics? 1/8/2020 • Purity Monitor, temperature sensors, cameras? • Setup of new DSS alignment, new APA/CPA positions • Better cleanroom set-up, we did not have appropriate ventilation and cleaning • Do we test the new floor concept we are using at DUNE? • How much consortia/CERN help to we get, or is most of the work done by the Ash River crew?
