Contamination Control Update
Contamination Control Supplies Area Reorganized:
The CC Supplies area in the entrance to LVEA has been re-organized and supplies clearly labeled. 
The heavy use supplies like wipes and foil are in the most obvious and easy to grab location. 
NOTE: The different types of pre-saturated and dry wipes are not interchangeable. General rule of thumb is only use the red pre-saturated or dry Vectra Alpha wipes on Class A parts. (Rest are for "gross cleaning" and floor mop.) The supply shelf is labeled with which one to use, if in doubt ask Jeff B. or Margot.   
The more advanced cc tools like the witness wafers, PET swipe tool, 1'' optics or Top Gun ionizers should only be used by experienced operators. If you think your work in the LVEA cleanrooms/chambers would benefit from using these, contact Jeff Bartlett or Margot Phelps first for assistance. 

Contamination Control work in HAM chambers with Jeff B.:
We are utilizing the new PET swipe tools to track surface contamination during install in HAM4-6. Yesterday Jeff B. took swipe samples of the tables in HAM4, HAM5 and HAM6. We will replicate this at the start of different in-chamber activities to track surface particulate through different install tasks. 
Also plan on chamber inspection and any necessary cleaning of these HAM chambers this week, whenever we can get in there to do so.
