NBI Decon: Decon continues on Lid, Magnet, Shield, 90 inch flange,
and smaller pieces. Decon has resumed on the calorimeter. The Calorimeter Vees
were repositioned and shields removed for greater access. Steady progress and
reduction of contamination has been noted with some cleaned areas having dropped
the targeted two orders magnitude reduction in contamination levels. Use of
occasional deionized water rinses continues. More items have been surveyed out
below 100kdpm and have been moved out of the high contamination area. On the
beam box, the front duct support structures and pivot point connection was
disconnected from the box and wipedowns started so these items so that they can
eventually be discarded and shipped. These larger items required the use of the
crane.
