2. Introduction

The CORELLI Spectrometer at SNS has requested a new Fine Radial Collimator (FRC) to be designed and procured to accommodate high field magnet sample environments. These high field magnet sample environments do not fit inside the existing collimator assembly.

3. Scope

This specification defines requirements for materials of construction, fabrication, inspection, and delivery to the Company of a complete Fine Radial Collimator Assembly. The Fine Radial Collimator Assembly shall be installed in the CORELLI Spectrometer Instrument.

The Fine Radial Collimator Assembly, hereinafter referred to as the Collimator Assembly or FRC, is described in the following sections. Any minor part not specifically defined, but required for complete assemblies, shall be considered included herein, unless specifically excluded.

Herein, Seller refers to parties responsible for providing the fabricated Collimator Assembly within the scope of this specification. The term “Company” refers to UT-Battelle, LLC and its representatives, including the SNS.

The Seller is responsible for fabrication, inspection, packaging, and shipping a complete Collimator Assembly in accordance with the requirements of this specification. Any exceptions to this specification shall be clearly noted as such in the Seller’s proposal documentation. Where exceptions are taken, the Seller shall propose alternatives.

4. Equipment Specification

The CORELLI Sample Scattering Vessel (SSV) consists of a sample chamber and a detector chamber. The chambers share the same vacuum space. The Collimator Assembly will mount inside the sample chamber of the vessel. Renderings of the CORELLI Vessel and these vacuum spaces are shown in Figure 1.

DETECTOR CHAMBER

SAMPLE CHAMBER

Figure 2: Plan view of CORELLI detector and sample vessel

The Collimator Assembly is composed of neutron absorbing blades with an angular separation of

1.3 degrees (blade center to blade center) as illustrated in Figure 3 and the Appendix. The blades consist of thin supporting foils coated with neutron-absorbing material. The blade-to-blade angular separation and the alignment of the blades in a true radial direction are critical to the neutronic performance of the collimator. The final blade separation should be identical over the entire span of the collimator, and the locational tolerance should be as tight as possible. The Seller shall clearly specify in the proposal submittal their fabrication tolerances for angular separation between blades, the angular deviation from a true radial direction, and the tolerances of the precision mounting system in the horizontal plane and tilt.

The Seller shall submit a dimensional inspection report prior to shipping the Collimator Assembly. The documentation shall include the as-measured average deviation of the angular separation between blades, the angular deviation from a true radial alignment of each blade, and coating thickness at a random location on each collimator foil.

The Seller shall provide 24 additional blades to the Company. The blades shall be packaged in a rigid container suitable for long term storage of the blades.

Collimator foils shall be of the stretched-film type. The foil design should be optimized to minimize thickness. The neutron absorber material shall be isotopically- enriched boron 10 carbide powder enriched to 96% or greater. The powder shall be mixed with a vacuum compatible binder component. The Company shall provide the Seller with the Boron 10 powder. The Seller shall clearly specify in their proposal submittal the following information:

• Foil material type

• Foil thickness

• Required Boron 10 carbide enrichment %

• Coating thickness (coated blade thickness minus foil thickness)

• Required Boron 10 carbide grit size

• Required mass of Boron 10 powder

The Company requests the Seller to comment upon the design capability for individual replacement blades to be installed and tensioned. If replacement blades can be provided the Seller shall provide a procedure for installing replacement blades.

The inner and outer radii of the collimator housing are shown on drawing BL09-20-M8U-8709- A10000 and in Table 1.

The Collimator Assembly will reside in the vicinity of high neutron and gamma fields as well as large magnetic fields. The structure of the radial collimator shall be constructed of non-magnetic materials, either stainless steel, titanium, or aluminum. Aluminum is the preferred choice due to its lighter weight and nonmagnetic properties. The Company requests the Seller to specify in their submittal the material alloy for the proposed collimator body and structure. The Collimator Assembly will be operated in a high vacuum environment, so the Seller shall use suitable materials and provide a means for trapped air to escape from mechanical interfaces.

During maintenance or when large sample environments are in use, the radial collimator will be removed from the instrument. Holes to accommodate both alignment and lifting features (tapped in the frame) shall be provided.

Requirements

4.1 All components must be compatible with a vacuum level of less than or equal to 1e-7 Torr.

4.2 All materials used must be compatible with the expected stray magnetic flux density of 600 Gauss.

4.3 The frame of the fine radial collimator shall have an inner radius of 16.5 inches, and an outer radius of

25.5 inches.

4.4 The collimator shall consist of 2 pieces. One with an active area of 78 degrees and one with an active area of 93.6 degrees.

4.5 The blade vertical active area shall be a minimum of 29 inches and a maximum of 32 inches and the overall height shall be no more than 38 inches.

4.6 The width of the blade active area shall be 9 inches.

4.7 The angular separation of the FRC blades shall be 1.3° blade center to blade center.

4.8 Blade Foil Thickness shall be no thicker than 0.095 mm to reduce the effect of shadowing on the detectors.

4.9 Each side of each blade foil shall be coated to a minimum thickness of 0.025 mm and shall not exceed

0.035 mm.

4.10 The tilting of the blades shall not be more than 0.05 degrees.

4.11 Blades must be flat and straight to minimize blockage of the primary scattering neutron beam.

4.12 The blade coating shall absorb neutrons between 10 meV and 200 meV.

4.13 Minimize the shadowing from any structural components in the collimator on the detector. The maximum angular range for a structural component is 1.3 degrees.

4.14 The collimator or pieces of the collimator and the lifting fixture shall fit through the D32 sample environment flange which is 32 inches in diameter.

4.15 The collimator shall have covers that can be placed on it when moved in and out of position.

4.16 The collimator shall be mounted on a baseplate with precision mounting provisions.

4.17 The mounting structure shall allow for precision alignment within 0.1 mm in the horizontal plane and

0.15 degrees out of plane (tilt).

4.18 The collimator shall not create forces that exceed 1700 N in the horizontal and 5000N in the vertical.

The company shall perform analyses on the seller’s design to validate this requirement.

4.19 The collimator assembly shall have a minimum of size M10 lifting provisions on the top piece and mounting/alignment provisions on the bottom piece.
