4 ingredients to contract

1.) MOU: Memorandum of Understanding,

2.) SOW: Statement of Work

3.) Detailed Schedule

4.) Sole Source Justification

5.) Contact person: Pre Award Dave Harris? Approve Terms and conditions

University gets a Purchase Req: covers SOW, Terms & Condition, & Schedule.

We respond with proposal containing exceptions and work plan. 1 team of 2 stringers can do a wire in 6 minutes. Stringers spend 1/2 of their time stringing the rest of time preparing , Q&A, ... 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.

Then they respond with contract.

"Cost Reimbursable" contract, University not liable if we go over budget

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

Need a hand rail system so people don't fall off the ledge because they mistake the clean room wall for a solid structure.

Dimensions of door from loading dock to clean room
65" wide
90" high

The doors into and out of the different areas will be 9'8" high in order to help facilitate the transport of equipment into and out of the different areas of the clean room.

The desks in the clean room will act as a table top area to place tools and other equipment currently in use during the construction of the wire chambers. Also, they will serve as a place to perform any calculations or other miscellaneous work that may come up while construction is ongoing.

The cabinets on the other side of the room will be a permanent storage area for all tools and equipment not currently in use at the two work stations.

The path in between the workstations and the cabinets will be kept clear of all obstructions in order facilitate the movement of equipment into and out of the room as needed.

The two workstations will be where the wire chambers are constructed. The workstations will have a standing/sitting apparatus built around them in order to help those who are stringing the wire chambers to have better access to the chambers from above. Schematics for these will be uploaded as they are designed.

The heavy equipment storage area will be where all the heavier equipment (i.e. dollies, fabrication materials, etc...) that will not fit, or does not need to be stored in the individual work station cabinets will be kept.

The HEPA filters will cover roughly ~10-12% of the ceiling in order to maintain a Class 10,000 environment. The filters will move approximately 35-40 air volumes per hour.

Overhead lighting will be suspended from the frame in order to provide sufficient lighting for the room occupants to work within.

Pictures of Path from Dock to clean room

As measured on the spit in the JLab clean room on April 28, 2011. The narrowest part of the R1 detector was 78". A door should accomodate 78" + box.

The Tip of the stringing fixture was 13' 5" high from the floor.

Below are pictures showing how our R1 mock up, an equilateral triangle 8' on the side, passes from the loading dock to the clean room area.

The 8' wide mock up is a few inches larger than the loading dock door.	The mock up is just able to pass through the door when standing up.

The R1 chambers will pass through 2 newly cut doorways to the clean room

The 8' wide mock has several inches to spare going through the first doorway.	The second doorway is the same width as the first.

Pictures of the ISU Squash Court

6/18/09

The clean room needs space for instrumenting.  The DC will be layed horizontal so PC cards can be mounted and tested.

6/24/10

11' = hook height in stringing clean room

There are 2 stringing strong back and 6 shipping strong backs. They bolt on separate sides of the chambers.

 Idea:  Instrument the chamber on the ledge above the squash court.  
Put a lift on the pole which we can use to turn the DC from its standing (stringing) position to 
its horizontal (instrumentation) position then "swing" it over onto the squash court ledge.

No Halogen lighting.

Think about air conditioning. People are space heaters.

Have shoes specific for clean room instead of booties.

Here is a preliminary floor plan for the Updated clean room in the ISU Basement

Pros and Cons of Locations

Physics Basement

Pros

1.) similar size to ODU just 5 feet shorter.

    20x39x15'   -vs- 20x40x20;

2.) more quality control: 4 Physics professors more likely to look in on construction in between classes

3.)established record of temperature control

4.) closer to other facilities; machine shops, electronics, ...

Cons

1.) must move detector standing up to get through 6' hallway

2.) more heavy lifting when bringing in and out of basement (this is only 2 day out of the months involved in construction)

Airport

Pros

1.) Plenty of Room

Cons

1.)adds > $10k to cost of clean room

2.) far away from professors eyes (could be a pro)

ODU's Clean Room

ODU's current clean room size:

20 ' high
20 ' Width
40 ' Length

CLAS 10,00 clean rooms

File:ODU CleanRoomDesign.pdf

Environmental control needed

Temperature control constraint is [math]\pm 2\% :\frac{7\% \;\;change\;\;in \;\;tension}{6 \;\;Degree \;\; Farenheit}[/math]

The wire tension can fluctuate no more than 5% from the mean wire tension specification.

This means that the temperature should be controlled to within +/- 2 Degrees Ferenheit

Humidity control: 55 % or less

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.

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.

The temperatures measured after changing the temperature set point to 72.

Temperature Oscillations observed before adding a tarp over the large doorway

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.

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.

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?

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

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.

July 2011 HVAC performance

6/6/11

Construction begins in the clean room. I opened the tarp over our big door a little bit and now I see temperature oscillations again.

6/7/11

The first few days of July were stable but there was a positive temperature gradient slowly increasing the temperature about +1/3 degree F per day. Then on July 4 something caused temperatures to fluctuate at least 1 degree within a day. Could it be that the university turned off the AC over the weekend and there was a delay seeing the building aclimate?
