NOvA Protoblock completed

The NOvA prototype block was assembled at Argonne National Laboratory and shipped to Fermilab, where it sits in the MINOS surface building. The photo below shows the protoblock with NOvA collaborators, taken at the April 2010 collaboration meeting. Six of these are needed for the Near Detector. The Far Detector will be 4 times the height, 6 times the width, and 30 times the lenght of the protoblock.
