| + | - Chiller water turned black due to the break down of glycol in the cooling water (causing the cooling water to become corrosive). | ||
| + | |||
| + | - 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. | ||
| + | |||
| + | == 06/19/2014 - JH == | ||

| - | 8/09/2011 - Roughing pump oil changed. Old oil was brown and had significant amounts of debris floating in it. Added a permanent maintenance log to the blue binder holding all of the user manuals for the system. | + | == 6/17/2011 - RW == |
| - | 6/ | + | - Inside of bell jar and all surfaces cleaned. Shutter operation fixed. Ion gauge degaussed; now reads more realistic pressure. |
