Value Engineering
Component Value Management /Design Alternatives Considered
Diagnostics All the diagnostics requirements were optimized to meet the experimental needs for all the instruments. Significant cost savings can be realized from common designs, both in PED, as well as in manufacturing.
Optics The following optical components requirements were optimized to meet the experimental needs for all the instruments: Pulse Picker, Attenuator, Harmonic Rejection Mirror and Be Lenses. Significant cost savings can be realized from common designs.
1µm Sample Chamber
Design alternatives were studied to accommodate various detector locations, allow for rapid access to internal chamber hardware and to maximize the reconfiguration capability of experimental hardware in the same chamber.
1µm Sample Chamber
Worked with a vendor to provide in-vacuum nanopositioning piezo stages capable of sustaining a higher load capacity. This collaboration lead to a gain in the flexibility of hardware reconfiguration by utilizing smaller stages.
1µm Precision Instrument Stand
Utilized the same concept as the LCLS AMO Instrument to save design costs due to similar stability and precision motion requirements. Significant cost savings can be realized from common designs.
Many trade-offs have been considered in the CXI Preliminary DesignThe CXI team will continue to purse cost effective approaches for all aspects of the instrument design/fabrication/installation

Summary
CXI designs are mature and concepts are based on proven developments made at FLASH and SR sources CXI has an established design with a consistent cost estimate. Approximately 90% of the materials costs based on vendor quotations, catalogs, or previous orders (Total procurements:3,467K$, Total based on quotes:3,164K$)Critical Design Thrust
Kirkpatrick-Baez Mirror Systems
Required Long Lead Procurement1µm Kirkpatrick-Baez Mirror System
Critical Path “float” reasonable for total schedule durationMajor Risks are mitigated with an implemented BCR to the “preliminary baseline” which includes a second dedicated Sample Environment for the 1µm KB system CXI and LUSI ready for CD-2 Approval!
