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.

ISU Clean Room Facility
- The chamber's longest wire should be lifted 4 ft off the floor.
- Need a hand rail system so people don't fall off the ledge because they mistake the clean room wall for a solid structure.

File:BasementRenovationDrawing 6-28-10.pdf Changes to machine shop door
File:BasementRenovationDrawing 7-26-10.pdf Maybe the Final design with 8' hallways and 8' doors to the clean room
Floor paint
ODU's clean room floor paint is a good choice, be sure to clean the concrete extremely well before application.
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.
Clean room floor plan for Basement and Airport
Here is a preliminary floor plan for the Updated clean room in the ISU Basement
File:Clean Room Squash Court.eps
replace the above with a PNG or JPG file so we can see it in the wiki
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)
Construction Quotes
We are currently waiting on quotes from the following companies on the construction of the Clean Room (both specs) at ISU. They are Modular Clean Rooms and Clean Air Products. Once quotes are received, pdf's of the quotes will be uploaded online.
2010 July 14
Quote from Clean Air Products for the ISU Basement:

File:Clean Air FilterDescript 10-15-10.pdf
File:Clean Air Quote No Filters.pdf
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.
HEPA Filters
Due to the cost of HEPA filters, a multistage filtration system will be used with the HEPA filters at the end of the system in order to insure the longevity of the HEPA filters.
More information will be forthcoming on this in the future.
ODU's Clean Room
ODU's current clean room size:
20 ' high 20 ' Width 40 ' Length
CLAS 10,00 clean rooms
Environmental control needed
Temperature control constraint is
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

Cleaning Procedures
R1 Construction preparations
Wire Tension
A Helmholtz coil is used to test the wire tension
Below is a write up from BaBar
File:Device2MeasureWireTension Covery BaBarReportTNDC-96-39 1996.pdf
File:ODU WireTensionMeasurements 10-2009.pdf
An excel spreadsheet to calculate fields for such coils is given at
http://clasweb.jlab.org/drawings/CLAS12/DRIFT_CHAMBERS/Helmholz_calculator.xls
The formula is from Physics 10X but more importantly it contains wire parameters useful for the calculation
Discussion items
1.) Budget
- JLab to ISU travel for JLab personnel to inspect operations
- shipping container for R1 chambers
2.) Clean room
cost =
assume we copy the ODU clean room
Using IAC conference room space, need to remove carpet and paint floor.
3.) hiring timeline
9/08 NSF proposal submission
4.) stringing platform and DC stringing support arm
5.) Manpower
6.) MOU to support post doc request or faculty release time
7.) Stringing equipment
a.) crimping tool
b.) glue
c.) wire or feedthroughs?
d.) wire tension measurement (PC, Magnets, associated electronics
A few pictures ff the R1 full size proto type from my JLab visit on 9/16/07. It is about 6 feet tall. CLAS12_R1_Prototype_9-16-07

Construction First R1 Chamber at JLab
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.
