A man stands near the partially completed NOvA far detector in Ash River, Minnesota. The detector, constructed entirely of PVC, stands 50 feet tall and 50 feet wide. The completed detector is roughly 200 feet long.
The NOvA near detector, built underground at Fermilab in Batavia, Illinois, is roughly 47 feet long, 14 feet high and 10 feet wide. It is constructed of the same material as the far detector.
