JLab expects a crew of 5 people. If we think we can't make the schedule we need to ask for more people. Stringers hourly rate ($30-$35/hr with overhead and benefits). Lead stringer is +$5/hr more.

		+
		+	Can we survey to 50 microns? No. 200 microns.

		+	===HVAC performance June 2011===
		+
		+	The HVAC system has been repaired. It was set to a temperature of 66 +/- 2 degree F. I saw the cooling light turn on at least once. On June 21,2011 the set point was changed from 66 to 72.
		+
		+	[[File:HVAC_4weekTempStability_4-11.png\| 200 px]]
		+
		+	Below is a snapshot after I turned the set point from 66 to 72.
		+	It looks like the cycle time was about 20 minutes when set to 66 degrees and 2 degree stability.
		+
		+	[[File:HVAC_Heating_4-21-11.png \| 200 px]]
		+
		+	The temperatures measured after changing the temperature set point to 72.
		+
		+	[[File:HVAC_Heating_4-22-11.png \| 200 px]]
		+
		+
		+	Temperature Oscillations observed before adding a tarp over the large doorway
		+
		+	[[File:HVAC_Oscilation_4-22-11.png \| 200 px]]
		+
		+	Some IAC personnel moved the tarp for a little while at time index 18:40. Fortunately there will be 2 doors put in. One where the tarp is now and another 5 feet towards the basement exit. Otherwise, I would worry about the impact of opening the large door on stringing.
		+
		+	[[File:HVAC_TarpOpened_4-22-11.png \| 200 px]]
		+
		+	The temperature seems to be more stable now with the tarp over the doorway, allowing the HVAC to control the temperature in only the clean room area. Below is a graph of the temperature in the room over a 6 hour period starting at 8 am until 2 pm on June 24, 2011.
		+
		+	[[File:HVAC_WithTarp_4-23-11.png \| 200 px]]
		+
		+	Below is a plot of the temperatures recorded over the last 7 days (4/18 - 24 / 11) when all the changes were happening to try and bring the temperature up to 72 degrees.

		+
		+	Below is a plot of the temperatures recorded over the last 7 days (4/21 - 27 / 11) . There appears to be a slow rise?
		+
		+	[[File:HVAC_TempLog_4-27-11.png \| 200 px]]
		+
		+	;6/28/11
		+
		+	I went down to the clean room and and saw that the Duct work was started. There are open holes into the adjacent room right now which need to be closed up.
		+
		+	;I also saw that the set point has been raise to 73 degrees. This explains the temperature rise above.
		+
		+	;8/11/11
		+
		+	Began moving the temperature sensors to new locations in the clean room. We plan on mounting them at locations which will measure the stringing temperature at the top and bottom of a chamber while we are stringing the chamber
		+
		+	[[File:HVAC_TempLog_8-12-11.png \| 200 px]]
		+
		+	;8/24/11
		+
		+	Installed an air deflector on the 5th vent furthest from the HVAC unit at approximately 11:30 AM, fourth vent furthest at ~3:00 PM, and 3rd vent at 3:15 PM.
