 +- Chiller water turned black due to the break down of glycol in the cooling water (causing the cooling water to become corrosive).  Chiller is being flushed, sanitized, and refilled by [[http://www.chemaqua.com/index2.asp|Chem-Aqua]]. 
 + 
 +- Update to the waterlines for cooling the evaporation terminals and crystal monitors is complete. 
 + 
 +- Water leak found for line going into diffusion pump, possibly caused by the corrosive water in water the lines.

 +- Diffusion pump oil changed. Refilled with 200 cc Dow 704. Old oil had yellowish color. No visible debris. Some tarring on the DP walls. Fixed minor leaks in deposition rate detector water lines. Chamber now holds at 0.1 Torr for 3+ days.
