NBI Decon:  Improvements in purge air flow, restart of the dehumidifier, and additional decon maintenance on floors and equipment have been successful in reducing contamination levels that were starting to build up around the Test Cell. Decon work continues on the box using the large capacity sprayer and also wipedowns using long poles. Planning to enter the box for examination of panels and additional internal wipedowns is underway. Decon efforts have started on the ion dump with wipedowns on both the exterior shields and the beam impinged interior copper. Close inspection confirms the need to change the full energy dump while also confirming the intent to reuse of the half and third energy dumps. All major components have now received some decon with resulting contamination levels demonstrably reduced. Low level decon on shields also continues as manpower permits. All of the OMA box internal shields have been removed allowing improved access and more extensive cleaning. Rad trash and rad laundry have been bagged and collected for removal from the Test Cell and processing by HP and ERWM.
