NOTES:
1.2  We couldn't insert rods into 5 of the source holes because of broken, loose or distorted spring pins.  Some pins could be pushed back into the holes, others had to be broken and removed.  One submodule, IL 022,  had a crooked spacer plate that would not allow rods or source tubes or tiles to be inserted.  This module was returned to ANL to replace the submodule.  It was sent back to MSU on Aug. 8, 00.

NOTES:
7.5  We used the air nozzle attached to the TV carriage on this module after polishing.  The vacuum cleaner was also pulling air through the girder while this was being done.  We had not been doing this on previous modules and in retrospect I (RJM) think it was a mistake.  After the QC6 scan, we removed one of the aspirin tubes to check low responses on a set of fibers and found paint flakes on that aspirin tube.  I suspect that the air nozzle stirred these up and they were attached to the polished end of the aspirin tube by static charges.

NOTE: Tiles are numbered from the beginning of the cell, starting at the tile closest to the ITC end of the module. Count every other profile to count the tiles. Odd tile layers start at the cell boundary (count from the first profile), even tile layers start with a spacer plate (count from the second profile). The tile counting stick makes it easier to locate the tiles.
