Herc-Higher Education Recruitment Consortium

The primary goals of the DUNE and ProtoDUNE Trial assembly work at Ash River is to develop all of the installation procedures required to build a large 40-kton liquid argon neutrino detector a mile underground.  This includes any special materials handling equipment or tooling to safety and efficiently prove that it can be done.  Developing the Hazard analyses, installation proce-dures, engineering notes, and drawings before they are approved by the University ES&H is part of this process.  The trial assembly work is the first full integration of all the different detector components manufactured in Universities and National Laboratories from around the world, all of which have never been assembled as a completed unit.  These tasks require a combination of research, coordination, and communication to successfully be completed because of remoteness and the small staff operating the NOvA Far Detector Lab in Ash River, MN this job also requires 24/7 on-call to keep the building and the NOvA detector operating 100% of the time.  All employees share in this task and have completed several months of required training. Work at the NOvA Far detector lab affects not only the work unit within the School of Physics and Astron-omy but also the Fermilab who supplies the grants for both the NOvA Far detector and the DUNE Project.

JOB DUTIES WITH PERCENTAGE TIME:
