Recent photos from Ash River, Minnesota, illustrate progress at the future site of the NOvA detector facility, a construction project funded in part by the American Recovery and Reinvestment Act.
-
- The 20-foot-deep hole outlines where the future detector facility will reside. Next, construction crews will deepen the hole to 40 feet.
-
- Construction crews drill to help excavate the site.
-
- Pulverized rock from the excavation will form the base for roads on the site, serve as backfill to support the structure of the detector facility and become part of the roof of the detector building to shield the experiment from cosmic and gamma rays.
-
- What used to be mud is now a road to the NOvA site, covered with gravel from the excavation for the detector facility.
