Additional FTIRs taken: upper fins, lower fins, and the ring. A dust monitor set for continuous sampling was set up in the chamber cleanroom.  BSC flooring was installed. Support tube bodies were inspected since fibers were spotted on the BSC-7 support tube bodies. The support tube bodies had fibers attached in various locations (most on the underside). A few pix are attached. The support tube nozzles and bellow were inspected. Debris was found in all nozzles. A couple of pix of these as well. Then, the support tubes were wrapped in two layers of foil, wrapped in C-3, and the C-3 was secured with Al foil strips. Dust barriers were placed in the beam tube nozzles. The compressor air lines were blown out prior to use and were found to have reddish watery residue. The wipes were taken to John for inspection and OK.(John was in meetings so we didn't turn an air drill in chamber today.)Equipment was staged by the dome so that documentation and conflat removal can start tomorrow.
