AL-1803-2752 A Statement of work: SAXS Flight Tube for 12.3.1 Endstation

6. INTRODUCTION

The purpose of this technical specification is to provide information needed by the subcontractor to complete the design, manufacture, and testing of a new SAXS Flight Tube (SFT) to be installed within the existing beamline 12.3.1 experimental hutch. The FT will be approximately 4m in length and 1m diameter; however the actual dimensions shall be proposed by the subcontractor based on optimal use of the available space. It is intended to house a Dectris 6M vacuum compatible detector and to translate it along the X, Y and Z directions within vacuum. The detector itself is outside the scope of supply.

The FT will be installed within an existing endstation hutch which cannot be disassembled or modified for access. Therefore, it is essential that all components are able to pass through the existing entryway. Motion of the FT will be required for initial alignment and for occasional realignment to a new optical axis if the upstream KB mirrors are retracted.

Samples will be mounted on a SAXS sample environment cart directly in front of the FT. There shall be a gate valve near the sample end of the vacuum tube that will allow the vacuum tube to interface with small portable sample vacuum chambers. It shall also have a vacuum-interlock system to close the gate valve in the event of leaks and appropriate protection against over pressurization such as a pressure relief valve and burst disk.

The FT shall include additional motions for beamstops and a detector cover. The detector cover shall protect the entire detector face from damage, and it shall be movable in and out of the beam.

The scope of supply shall include the FT chamber components, support structure, internal mechanics and the actuator drives. Motor controllers, cabling, and motion controls shall be listed as an optional package, as detailed in the SOW.

Vacuum hardware including roughing pump, low vibration sustaining pump, gauges, vacuum controllers etc. shall also be detailed as an optional package.

The seismically certified floor mounting assembly is outside of the subcontractor’s scope of supply. However, the subcontractor shall supply sufficient information concerning mass and mass distributions to enable LBNL staff to design an appropriate seismic restraint system.

7. REQUIREMENTS DEFINITION

Shall, should, may, and will are used to define every requirement listed in this document. The definitions of these terms are as follows:

- Shall is a requirement that must be implemented

- Should indicates a desire and can be interpreted as ‘best effort’

- May indicates a desire and can be interpreted as ‘nice to have’

- Will is used to inform intent or declaration of purpose and is not a requirement

8. COORDINATE SYSTEM (CSYS)

The following CSYS will be used in this document:

The beamline CSYS, oriented such that the Z-axis is in the direction of the beam propagation from the source, and the Y-axis is normal to the floor, positive upwards. The positive X direction is outboard of the storage ring. X, Y, Z are designated transverse, vertical, and ci al ly R el ea se d to th e

longitudinal. Starting from the beamline CSYS, a sequence of three intrinsic rotations, RX, RY, RZ, also designated pitch, yaw and roll.

9. SPECIFICATIONS

9.1. Spatial envelope and limitations

The new SAXS flight tube will be installed within the existing 12.3.1 beamline endstation hutch

(Figure 1). The inner longitudinal dimension of the hutch is 6.695m along the beam axis. The space-claim for the FT begins 2.35m downstream from the inner face of the upstream wall leaving

<4.346m available for the tube. However, note that the upstream and downstream hutch walls are not parallel (Figure 2). A CAD model of the hutch and beam geometry can be provided upon request. Space and access on the outboard side is limited; note that the outboard hutch wall is not parallel to the beam axis. Clearances between the beam and hutch wall are covered in more detail in section 9.2.

Under normal operation all access to the tube and its contents shall occur on the inboard side. If access to the downstream end is required (or foreseen) by the subcontractor than the subcontractor shall leave sufficient space between the downstream end of the FT and the hutch wall to facilitate such access. The length of the flight tube should make best use of the available longitudinal space to maximize the available range of travel for the detector. The final dimensions of the FT spatial claim shall be confirmed in writing by LBNL at the time of the PDR.

The existing structure of the hutch cannot be disassembled or modified in any way to facilitate transportation, assembly, installation, or access, to the flight tube or any of its components; with the exception of labyrinth removal which is permissible for cable and utilities pulling (subject to compliance with ALS radiation shielding modification procedures). All access to the work site is via the existing hutch door (Figure 1). The inner dimensions of this door are 2032x1219mm (HxW).

The subcontractor shall design the assembly such that all components and equipment necessary to install and commission the FT can pass through this door.

Requirement

Primary access to the FT and its contents shall be via the inboard side

If access to the downstream end of the tube is required or envisioned, then sufficient space should remain between the tube and hutch wall to facilitate such access

All components and necessary equipment shall be able to pass through the existing entryway ci al ly R el ea se d to th e

9.2. Beam geometry and alignment of the FT to the beam

The primary beam axis is parallel to the floor at a height of 1240mm above the floor. However, to allow sufficient space for seismic anchoring between the FT support structure and the floor the subcontractor’s scope of supply shall end 75mm above the floor level. See section 10.3 for seismic anchoring requirements. The support structure of the FT shall include XYZ adjustments suitable for aligning the FT to the beam axis with sufficient accuracy to meet the alignment specifications described in section 9.5.

A KB mirror pair is positioned upstream of the FT to provide variable beam focusing. It is envisioned that these mirrors will be individually retractable. This KB-retracted beam path will be for occasional use or to accommodate particularly unusual experimental geometries that require a descending beam path. Access to additional intermediate geometries between the “inserted”

and “retracted” geometries is not required. The subcontractor should provide sufficient adjustment in the Y and X directions to permit the flight tube to be realigned to the alternative beam axis by LBNL staff. This will entail a pitch rotation of 9mrad downwards about a point 2m upstream of the start of the flight tube volume claim and/or an inboard yaw rotation of 9mrad about a point 1.5m upstream of the start of the flight tube volume claim.

Realignment between alternative beampaths can be achieved via manual adjustment. Although

LBNL may consider subcontractor proposed motorized solutions as an additional option.

per minute on a roughing pump and a 300L/s turbo pump.

All vacuum-facing components shall use vacuum-compatible materials.

The flight tube modules and endcap shall be connected to each other with Viton O-rings captured in half- or full-dovetail grooves. Use of grease on O-rings shall be strictly prohibited.

Flange, port, valve, and bellow connections shall utilize standard ISO-F or ISO-KF centering rings in aluminum or stainless steel with Viton O-rings. Use of grease on O-rings shall be strictly prohibited.

Neither the maximum stress under a vacuum pressure of ≤1×10-3 mbar nor the assembly weight shall exceed the yield stress of the applicable material. An FEA analysis shall be provided by the subcontractor demonstrating compliance with ASME BVPC Section VIII Rules for Construction of

Pressure Vessels, Division 2.

Access doors shall be hinged and sealed with Viton O-rings.

The FT should have three evenly spaced standard 6” ISO flanges for a vacuum-pump connections located along the bottom of the vacuum chamber.

Laboratory, Upton, NY, 09-Sep-2008.

9.4. Detector compatibility

The detector itself is outside the scope of supply. The FT shall be compatible with the Dectris

PILATUS®3 X 6M vacuum compatible x-ray detector. Compatibility requirements shall include the ability to support and translate the detector as specified within this document as well as the ability to meet all interface requirements specified by the manufacturer in “Technical

Specifications DECTRIS PILATUS®3 X 6M” v.1.2.4 and its successor versions including (but not limited to) mechanical, utility, electrical, environmental, interlocks, vacuum, and data interfaces.

Where onward connection to external interfaces is necessary (such as electrical, data, etc) the subcontractor shall include appropriate, and documented, interfaces that are external to the FT.

The 6M is currently not available “off-the-shelf” as a vacuum compatible model. The only detector that is vacuum compatible as standard (and currently available) is the 9M-V. Thus, the subcontractor shall (with the approval of LBNL), make appropriate assumptions about additional requirements for a vacuum compatible version of the 6M based on the manufacturer’s published

9M-V specifications as documented within “Technical Specifications DECTRIS EIGER®2 X 9M-V” version 1.8.3 and any successor versions. The FT shall be designed to accommodate the 9M-V as an alternative option to the 6M in the event that a vacuum compatible version of the 6M proves to be unavailable.

Requirements

The FT shall be compatible with the PILATUS®3 X 6M with additional requirements necessary for vacuum compatibility agreed with LBL

The FT shall be compatible with the DECTRIS EIGER®2 X 9M-V vacuum compatible detector

9.5. Motion requirements

The detector shall be capable of independent in-vacuum translation in the X, Y, and Z directions.

The X, Y and Z translations should be as large as possible subject to the spatial limitations of the beamline, exceeding the values below if possible and the FT should be sized accordingly. The X ci al ly R el ea se d to th e

10.2. CAD Integration

The ALS experimental floor is crowded, and integration tends to be difficult and subject to complex spatial constraints. At the time of the FDR the Subcontractor shall supply a CAD model in a mutually agreed format that is suitable for validating the spatial constraints outlined above in 9.1 and 9.2.

Requirement

The final design spatial envelope shall be validated by integration in the beamline CAD model at the time of the FDR

10.3. Seismic requirements

The FT will operate in a geologically active area near the Hayward Fault; therefore, the seismic anchorage design and the equipment support frames shall comply with the California Building

Code.

Due to unique constraints, the seismic floor anchorage design shall be done by LBNL. To this purpose, LBNL will design a floor mounting plate following the floor mounting plate tapped hole layout proposed by the Subcontractor. LBNL incurs all associated costs, however the

Subcontractor shall provide the following parameters and implement all recommendations made by the LBNL Structural Engineer.

Requirements

The Subcontractor shall propose a floor mounting plate tapped hole layout to be reviewed and approved by LBNL

The Subcontractor shall provide the following parameters:

- The weight of the complete FT assembly as configured for operation, including the 6M detector and all necessary cabling and utilities distribution required for normal operation

- The overall height, width, and depth

- The dimensioned location for the center of gravity (height and in plan)

- The magnitude and location of all vacuum loads

The equipment support frames shall comply with the California Building Code

In addition, the Subcontractor shall provide calculations that show that the equipment support frames, including but not limited to the support structure, the vacuum chamber, and the internal mechanics, comply with the California Building Code. The design and calculations shall be reviewed and approved by the LBNL Structural Engineer. Because of the close proximity of the

Hayward Fault, the seismic load requirements specified by the building code for the ALS are high, typically around 0.37 g-force vertically and 1.00 g-force laterally, in any direction. LBNL may assist the Subcontractor in defining the seismic load requirements.

The SAXS flight tube modules shall each have three fiducials visible from the inboard side, in locations to be reviewed and approved by LBNL in writing, each with datum related to the assembled cylindrical chamber axis, for installation at LBNL by LBNL S&A personnel.

Compact posts 29E064 or Heys nest 27K813 fiducial posts, or equivalent, (LBNL reserves the right to determine equivalency), shall be used

10.5. Lifting provisions

Access at the ALS is often restricted, and specialized lifting fixtures or attachment points may be needed. LBNL shall provide all information needed by the Subcontractor (e.g. list of available lifting equipment) to develop a suitable design and procedure by the time of the FDR.

All components shall have lifting provisions as required for assembly/disassembly and packing/transport per ASME B30 standard. They shall be capable of being hoisted by a manual crane with load limit of 1 ton (2000 lbs.) and maximum hook height of 2.67 m. The SAXS flight tube shall have a provision for a balanced lift of all chamber adaptor components when they are connected together.

Requirement

Installation and removal of the detector shall be possible at the beamline

Installation and removal of the detector shall be possible via an access port without splitting the primary tube

10.6. Electrical

The Subcontractor shall provide the system interconnect and wire diagram. Electrical safety will be reviewed before giving formal approval for initiation of manufacturing activities to ensure all

LBNL specifications are met.

An all-metal valve is not required, however if an O-ring sealed valve is envisioned then the O-ring shall face downstream

A vacuum interlock system shall be provided to close the gate valve in the even to a leak

The subcontractor shall, as detailed in the SOW, propose an optional package consisting of all additional vacuum hardware required for operation of the FT. This should include suitable pumps as required for roughing, sustaining baseline vacuum requirements with minimal vibration, vacuum gauges sufficient to cover the range from atmospheric pressure to baseline vacuum, controllers, and cables.

11. FAT

The Subcontractor shall develop a FAT procedure that demonstrates that all requirements listed throughout this specification are met in an environment that should be comparable to the ALS.

The FAT should be divided in four inspections: general inspection, vacuum acceptance, determination of the positioning performance of the controlled axes, and determination of the stability performance. FAT shall be reported in written form and an electronic copy of all results shall be provided
