Low temperature alarm was sounding upon arrival this morning. The temperature monitoring record shows a drop in temperature over the weekend that seems to coincide with a dramatic increase in humidity (Pocatello is currently experiencing uncharacteristically high humidity associated with rain and thunder showers). The temperature set point was increased to 69 degrees (per discussion with Dr. Forest). Stringing operations were haulted until temperatures began to stabilize. Temperatures declined again and the temperature set point was increased to 70 degrees. Temperatures seem to be holding between 68 and 69 degrees now.

After approximately 14:00, the humidity levels were above 55%. The humidity set point was lowered to 45% (per discussion with Dr. Forest). The humidity level immediately dropped and has not increased since the change.

While stringing operations were haulted, a clean was conducted in the cleanroom. After cleaning, particles were measured and were within specifications (0.5um = 11,700 particles per square meter and 5.0um = 1,650 particles per square meter).

Cleanroom temperatures were above 72 ° F this morning. The increase in temperature appears to coincide with a dramatic decrease in humidity from 51% to 30%. (Pocatello is experiencing higher temperatures with little humidity.) The temperature setpoint on the HVAC was lowered to 68 °. Stringing operations were haulted until temperatures decreased and stabilized around 71 °. At 10:00am the temperature setpoint was lowered to 67 °. Temperatures have decreased and stabilized between 69 ° and 70 °. (Screen shots of the temperature and humidity graphs were uploaded to the wiki.)
