    NOTES: 7.3:

  • Found that PMT37 had not been glued.  The aspirin tube was replaced and reglued.
  • We used a new saw blade on the polisher on the even side of this module.  It made more noise than the old blade and produced bigger chips.  The polished surface looked OK with the TV camera, but we decided to put the old blade back on for the odd side.
  • After the first QC6 scan was done, we find that the even side has large response variations that are correlated in tile locations over all layers in the cell.  We took out a few of the aspirin tubes and inspected the surface.  These show a bad polishing job on part of the surface as if the saw is cutting deeper than the diamond.  We removed the washers from all of the aspirin tubes on this side and repolished.

    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.
