Upstream from the MINOS Hall, preparations to install the large entrance door to the NOvA Near-Detector Cavern are complete. Fire protection and detection systems have been tested, and support posts are being installed around the entire hall to accept a 4-foot-high oil containment liner, which will protect the facility from an unintentional release of oil from the future detector.
