STATEMENT OF WORK 4200804233

1. Objective/Requirements This requirement is to provide a Vacuum Test Chamber, mounted on a wheeled and adjustable height stand.

Background:

The NASA Stories Program, Code 672 Helios-Physics, is producing a Neutral Atom Detector System, called RENA. The RENA Instrument is scheduled to fly on the International Space Station in 2025.

The Development, Space Environmental Testing and Calibration of the RENA Instrument will require a custom sized Vacuum Test Chamber, to be utilized in 2023

The Development, Environmental Testing and Calibration work, for the RENA Instrument, will be carried out in the GSFC Code 561 Radiation Effects Facility (REF).

The Vacuum Test Chamber, must be a custom non-standard size, in order, to be small enough to fit in the REF, and have large enough internal dimensions, to do multi-angular testing of the RENA Instrument.

Contractors, in the US, that are advertising expertise in the technology and producing like chambers, will be asked to bid on the task of providing GSFC-Stories, with a Vacuum Test Chamber, designed to meet the requirements of this task.

2. Characteristics, Scope, and Specs The contractor shall perform the following duties:

Construct a Vacuum Test Chamber, following descriptions supplied by NASA-

GSFC Code 672 o Width, Max outside width, 57 inch +/- .5 inch, mounted on the cart, rolling on wheels, lifting jacks can be removed.

o Height, Max 80 inch +/- 1 inch, mounted on the cart, rolling on wheels, lifting jacks, can be removed o Length, Max 90 inch +/- 2 inch, mounted on the cart, rolling on wheels, lifting jacks, can be removed o Inside Diameter (ID), 54 inch +/- .5 inch o The chamber, and parts will be made of stainless steel as per materials called out in the drawings. Drawing (203978-32 ) CHAMBER, BODY WELDMENT o Entrance Door, The chamber will have a door at one end of the chamber, o Door Opening, ID can be 51 inch +/- .5inch, o Door Seal, to be an elastomer seal as is standard in the vacuum industry, located and described, as per Drawing (203978-35 ) CHAMBER, RADIATION TEST ASSY.

o Ports flanged, with nipples, located and described as per Drawing (203978- 32 ) o Manifold, detachable, using standard 12” Con Flat flanges on the chamber and the manifold o Lifting Eyes, mounting for, Drawing (203978-32) STANDOFF, EYE BOLT, 1/2-13

MOUNT

o As per additional lists attached, “Chamber_Mods_5-9-2022”, “54inch diam Chamber_Mods_5-9-2022”, Provide/Construct a Table -Cart, to mount the Vacuum Test Chamber on, o which can roll on wheels, o or be stabilized with adjustable height screw jacks, o Height, chamber centerline 42” +/- 4 “, above the floor. See list with suggested model screw jack “Chamber_Mods_5-9-2022” Conduct Test, Vacuum/Pressure, finished chamber to attain leak rate of less than

(2e-10 std cc/sec, He leak detector )

Delivery, to S. Brown Code 561.4, NASA-GSFC, Greenbelt Rd, Greenbelt Md 20771, -B22 R 070B, in a timely manner to support, prototype testing, prior to June

3. Place of Performance The Chamber will be constructed, assembled and leak tested at the contractor’s facility

4. Period of Performance Testing, Vacuum Verification and Dimension Verification, shall be performed, at the manufacturer’s facility, before shipment to GSFC.

CHAMBER, RADIATION TEST ASSY.

5/9/2022

Changes to the design of the current chamber

1. The chamber ID should be 54” +/-0.5”, maximum outside dimension should be 57” +/-0.5” see redlined drawings for additional information

2. Its ok to reduce opening to use a larger door flange ring (2.5” width)

3. The CF flanges on the side of the chamber can be rotated to maintain the 57” maximum diameter/ width

4. Total length approximately 90” +/- 2”

5. Height to center of chamber on cart needs to be adjustable 43” +/- 4” (39”- 47”) Something like leveling (trailer) jacks with crank handles- https://www.mcmaster.com/2963T49/

6. Overall height cannot be greater than 80 “ +/- 1” ( it can be with the jacks at the lowest point i.e. 39” from center of chamber on wheels of course)

7. Cart construction preferred (80/20) 3”x3”

8. Nozzle manifold should be centered to the chamber- see redlined drawing

9. Nozzle manifold should be a separate part and chamber needs a 12”CF to attach manifold, a short nipple ~1.5” to 2” is probably needed. It’s ok to exceed the 15” as shown on the redline

10. Weld additional door hinges brackets to chamber so door can be mounted on either side. Door can be rotated (door can be made symmetrical)

11. Door Hinges should be more rigid than the ones shown on the drawings- door should be easy to close

12. Add ramp/ alignment guide to aid in door closing to compensate for door sag

13. Add 2 additional 4” CF ports as shown on redlines

14. All CF should have clearances holes – no tapped holes!

15. The wheels should not be cantilevered as shown in the redlined drawings

16. Inside of main body chamber should be electropolished or equivalent finish https://www.mcmaster.com/2963T49/
