We have repeatedly had issues with blocked feed throughs on both Sector 5 and Sector 6. Spent the afternoon cleaning out feed throughs on both chambers. We will use nitrogen to clear out any debris after the process is complete. There is a Field feed through at 167-11 in superlayer 1 that is completely blocked by glue inside the chamber. We also spent considerable time removing small metal pieces from inside Sector 6. They appear to be tiny circles of metal.
