97 Feb 11, 2013 Complete Stringing R1 C6
104 April 1, 2013 Ship chambers, fixtures, platforms and crane to JLab

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 6-16-10.pdf

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.

ISU Physics LoadingDock W 3-30-11.jpg ISU Physics LoadingDock H 3-30-11.jpg
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

ISU Physics CleanRoomD1 W 3-30-11.jpg ISU Physics CleanRoomD2 3-30-11.jpg
The 8' wide mock has several inches to spare going through the first doorway. The second doorway is the same width as the first.

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

Clean Room Squash Court.png

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 Quote.pdf

Clean Air Room 01.png Clean Air Room 02.png

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


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

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

The air actuated crimping tool:

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.
