On Monday and Tuesday, June 9 and 10, 2008, Physical Facilities will be working on the high-pressure steam system for this portion of campus. As a result, the Birck Nanotechnology Center will lose temperature and humidity control during that period. It is likely that we will see a 2⁰-3⁰F drop in temperature and a 5% increase in humidity in the offices, laboratories, and cleanroom. Laboratories with fume hoods will feel more impact than those without hoods. There will continue to be hot water in the bathrooms during this period. Please note that it will take 6-8 hours for the building to stabilize after steam is turned off on Monday and about the same amount of time for it to stabilize when the steam is turned back on late Tuesday afternoon. Please arrange your schedule to avoid temperature-critical and humidity-critical (such as positive photolithography) during this period. Our apologies for any inconvenience that this may cause, but it is a campus shutdown that is out of our control. Thank you in advance for your patience and understanding.
