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.

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

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 & Schedule
Mitigation
Start discussions with vendors early to guarantee their capabilities are consistent with our needs
Iterate specs with vendors early to find a workable solution before bid process
Vendor doesn’t meet specifications – Technical
Mitigation
Travel to vendor sites during fabrication
Have a quality control person supervise their final fabrication process and final surface characterization
Identify vendors with proven capabilities
Delays impact other systems – Schedule
Mitigation
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
Sample Chamber
Lack of information regarding 0.1µm KB delays engineering effort – Schedule
Mitigation
Same as “Delays impact other systems” above. Risk retired with BCR-2008-06-004: Addition of Second
Chamber and Precision Instrument Stand for the CXI Instrument
Particle Injector
Remote operation – Technical & Schedule
Mitigation
Leverage institutional efforts to solve this problem
Move injector to a CD-4C deliverable

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 Procurement
1µm Kirkpatrick-Baez Mirror System
Critical Path “float” reasonable for total schedule
duration
Major 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!
