Final Beamline Design Report
Guidelines and Review Criteria (SCD 1.20.95)
6.0 Final Beamline Design Report (FDR) Overview
The Final Beamline Design Report is part of the Advanced Photon Source (APS) beamline review process and should be planned for when approximately 90% of the total beamline design has been completed. Fifteen copies of the FDR are to be submitted to the APS Users Office. Approval of the Collaborative Access Team's (CAT) designs described in the report is required prior to installation of beamline components in the APS Experiment Hall. Components that have a long lead time for design or procurement can be reviewed separately from the remainder of the beamline, but enough information must be provided so that the reviewer can understand the context in which the component is to be used. Those components which are part of the APS standard component list need not be reviewed for their individual performance; however they should fit into the general scheme of the total beamline performance.
The review of the Preliminary Beamline Design Report (PDR) focused on the layout of the beamline as a whole and at a level that would permit the beamline components to be designed independently of each other. The final design report will focus on aspects of safety, scheduling, required APS support, and updating the information provided in the PDR. The topics to be covered in the FDR are:
- Layout Update
- Identify changes from PDR layout
- Provide survey plan and include expected APS support
- Update the ray traces provided in the PDR
- Component Design Update
- Provide component final design (reference if APS standard components are used)
- Assure compliance with the APS beamline vacuum policy
- Update PDR Work Breakdown Structure (WBS) based schedule
- Provide installation schedule
- Identify expected APS craft support and provide schedule
- Provide survey schedule
- Provide final Personal Safety Systems (PSS) requirements
- Provide Equipment Protection Systems (EPS) logic and interface requirements
- Describe final shielding design
- Identify chemical, electrical, fire, and other hazards that impact beamline design, and describe means to mitigate the identified hazards
- Identify program-specific hazards (e.g., high powered lasers, biohazards, chemical, etc.)
- Special Operating Requirements Update
- Identify special conventional facilities requirement
All significant changes from the information provided in Preliminary Design Report (PDR) should be clearly noted. (Significant in the sense that the changes will affect the scope of the beamline capabilities, functionality, constructability, or safety.)
Beamline designers should keep in mind in the design process that, as part of the Installation Readiness Review, the beamline components will be reviewed for compliance with standards such as NEC and those specified in the ANL ESH manual.
In reviewing design reports, the APS will note concerns that have been identified, but, ultimately, it is the CAT's responsibility to build and operate a productive facility that meets applicable safety standards.
Final Beamline Design Report Review Criteria
6.1 Layout Update
A plan and elevation of the beamline layout has been provided with clearly identified beamline components (e.g., slits, shutters, mirrors, monochromators, shutters, stops, etc.), beamline support facilities (e.g., beamline controls and data acquisition electronics, compressed gas storage areas, etc.), and aisle ways. CAD files of the layout have been provided to the Design Exchange.
Changes from the PDR layout have been clearly identified, and the impact on the beamline functionality is described.
A survey and alignment plan has been provided including the general scheme and the required survey fiducials.
Utility distribution is specified. This may be done with a layout drawing that clearly shows, as appropriate, information such as: tap, outlet, and breaker locations, pipe sizes, identification of electrical circuits, design of utility support structures, locations of heat exchangers, etc.
Changes from the PDR ray traces for optical apertures and bremsstrahlung shielding have been provided with the changes from the PDR ray traces clearly identified.
6.2 Component Design Update
Updated drawings, typically assembly drawings, and/or performance specifications have been provided for each beamline component at a level so that the reviewer can understand how the device is to function.
Documentation that the beamline is in compliance with the Vacuum Policy for APS Beamlines (refer to ANL/APS/TB-14) has been provided. The vacuum levels in each beamline segment and the location of in-vacuum, liquid-coolant joints should be indicated.
Beamline components were identified in the PDR as being either standard components, modified standard components, or user designed devices. State what changes, if any, there have been in any components.
WBS-based schedule information has been provided with the FDR and will provide the basis for proceeding with the beamline construction. Much of the schedule information required in the FDR is the useful to both the APS as well as the CAT to ensure that the required resources can be provided.
An installation schedule has been provided. The schedule should identify design, fabrication/procurement, installation, hook-up, and commissioning activities at a beamline-component level.
Components that will be procured through the APS are identified, and the required delivery date provided.
A schedule for APS support is included for:
- skilled trade support (e.g., electricians, plumbers, etc.)
- survey and alignment
- Personnel Safety System installation and check-out
The PSS requirements of the beamline have been provided, including:
- Identify components that need to be interlocked
- Identify components that need administrative control, and describe the nature of the administrative control (who needs to do what)
- Indicate the location of PSS hardware (e.g., control panels, search buttons, routing of PSS wire-ways, etc.)
- Provide a logic table to describe the configuration of the beamline components for the different modes of a beamline (e.g., monochromatic, white beam, station pass through, off-line, etc.)
- Provide a logic table to describe the required status of the beamline components to define the access to each experimental station (i.e., station secured no personnel access, personnel access permitted to station, or station administratively off-line).
If this information was provided with the PDR, any changes should be noted.
An updated EPS description has been provided. An identification of monitored components, the design logic, and interface requirements should be included. If this information was provided with the PDR, any changes should be noted.
The specification of beamline shielding is provided.
- Describe the type of radiation to be propagated (white, monochromatic, or "pink") in each portion of the beamline
- Identify where non-APS designs were used for shielding
- If shielding other than the APS standard design is used, an analysis must be provided assuring the shielding meets the same design criteria as described in ANL/APS/TB-7 and ANL/APS/TB-20
If this information was provided with the PDR, any changes should be noted.
The ozone hazard created by the beamline is described, as is the plan to mitigate the hazard. (Refer to Guidelines for Ozone Mitigation at the APS, within ANL/APS/TB-14.)
Identify chemical, electrical, high power lasers, biohazards, and any other hazards that will impact beamline design, and describe the plans to mitigate these hazards. When the hazards are beyond the expertise of the Beamline Design Review Committee, then advice and review will be sought from outside the committee.
- For beamline electrical/electronic instrumentation, identify potential electrical hazards and mitigation plans (e.g., grounding plans for ion pumps and vacuum chamber with ion gauges)
- Beamline designs may need to incorporate the means to mitigate hazards associated various chemicals. Identify hazardous materials storage areas, exhaust systems, gas handling systems, etc., and describe the plans for mitigating the hazards
Identify potential fire hazards including quantities of flammable liquids and gases in experimental stations and along the beamline. Identify enclosed areas that will be occupied during normal operations (e.g., a sample preparation clean area with roof). Of course, experimental stations are not occupied during normal station operations.
6.5 Special Operating Requirements Update
Identify special, (i.e., those beyond the capacities described in ANL/APS/TB-9) conventional facilities requirements.
