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



Procurement Strategy

Installation Effort

KB systems are “long duration procurement” items – requesting DOE long lead approval for 1µm KB system prior to CD-3BCritical path (through 1µm KB System) has 117d of schedule contingency



Risk Identification & Mitigation

Risk Identification/Registry complete and up to date as per “LCLS Risk Management Plan” PMD 1.1-002-r4 KB Mirror Systems

No vendor willing to bid on systems – Technical & ScheduleMitigation

Start discussions with vendors early to guarantee their capabilities are consistent with our needsIterate specs with vendors early to find a workable solution before bid process

Vendor doesn’t meet specifications – TechnicalMitigation

Travel to vendor sites during fabricationHave a quality control person supervise their final fabrication process and final surface characterizationIdentify vendors with proven capabilities

Delays impact other systems – ScheduleMitigation

Break the link between the KB0.1 KB mirror and the chamber by building a second chamber to be used early with the KB1 system only. Risk has been alleviated with BCR-2008-06-004: Addition of Second Chamber and Precision Instrument Stand for the CXI Instrument
