The wipe-down of BSC-4, which started this morning, was completed by the end of the day. That is a new speed record for the wipe-down of a BSC. The floor was re-installed in preparation for second vacuum and inspection tomorrow. *Note: FTIR results of HAM-10 ICC came through today. (Please see reports below.) All post-work results, with one exception, were at or below detectable. The exception, the center of the chamber floor, will be re-sampled, wiped down again, and then sampled one more time when we are back in the chamber to pull the dust barrier.
