Technicians arrange a vacuum suction lifter over a newly cleaned plastic module. This is the seventh of eight blocks for the NOvA near detector.

In the assembly building, technicians guide a vacuum suction lifter carrying a plastic module. When fully assembled, these modules form one of the eight blocks that will contain liquid scintillator in the NOvA near detector.

One of the NOvA near-detector blocks arrives in its new home more than 300 feet underground. Eight such blocks, each about 15 feet high, 15 feet wide and 6 feet thick, will make up the near detector.
