Comment on whether the component design is ready to proceed to final design

Form AP-391-000-59-0 Design Review Report

Introduction and outcome summary of the review: The design for the 1-micron system sample chamber appears to be appropriately detailed for this stage of the design process. The review committee did not express any major concerns regarding the design choices made so far, and the design team is urged to continue with the final design process. A few specific issues that should be addressed as part of the final design are given below, as well as general observations about the major design choices that have been made.

Findings/Action Items: The following issues should be addressed during the final design process, and the resulting decisions should be explained at the final design review:

• The vibration environment of the chamber should be considered, and the choice between using a rigid attachment to the floor vs a vibration-damping attachment should be explained. • The stability and alignment requirements of the system should be compiled. A breakdown of how each subassembly/subsystem contributes to that tolerance budget should be presented. • A calculation of the stability of the target position on the breadboard mounted to the vacuum chamber and series of linear and rotary stages should be carried out, particularly considering the long travel stages. • The system was specified to be 1800 lbs, close to the 2000 lb limit of the crane. Care should be taken in the lifting plan to ensure that the weight limit of the crane is not exceeded. Additionally, plans for rigging and fixturing the chamber should be included in the design. • The large number of in-vacuum motions create many possible clash configurations. Plans for limiting travel and preventing crashing of internal components should be developed. • The addition of a cryo-trap for the particle beam should be considered, and the decision to include or exclude a cryo-trap should be explained. • The choice between viton-sealed and all-metal valves should be carefully considered and explained.

Report No:TR-391-003-20 Page 2 of 3

Concerns: None

Observations: The vacuum specification for this chamber is 10-7 Torr. Both upstream and downstream areas of the beamline will operate at different pressures, including UHV in the mirror chamber shortly upstream. The plan is to include differential pumping isolation systems immediately upstream and downstream of this chamber. This is a good plan, and the calculations used to design the differential pumping systems should be presented at the instrument final design review.

This chamber includes a large number of in-vacuum motions, motors, and wiring. The plan is to include internal patch panels to allow removal of motors and motion stages without complete disassembly of the chamber. This is a good plan, given the moderate vacuum requirement for the chamber. Nevertheless, the motors, stages, and wiring should be chosen and installed with care to assure operation with minimal required maintenance.

Atomic resolution can be achieved for reproducible objects with crystallography Macromolecular crystallography has been extremely successful Molecular structure is crucial for medical applications and understanding of biological function. Inability to produce large high quality crystals is the main bottleneck. Important classes of biomolecules are difficult to crystallize to date. Membrane proteins Free electron lasers may permit structural determination without crystals

10 Sébastien Boutet [email protected] CXI Apodized Edge Apertures

If 1 part in 106 of the LCLS beam gets scattered off the slits onto the detector, there is on average 1 photon per pixel and the background is too high! LCLS Beam Soft edge apertures, such as etched Silicon minimize scattering. Use extra apertures to remove the scatter from the upstream apertures.

106 Armin Busse [email protected] CXI Summary

1 micron Sample Chamber preliminary design is well advanced Controls issues have been addressed in partnership with the Controls Group and are easily implemented Cost/Schedule No foreseeable schedule issues at this point, positive schedule variance Schedule Performance Index (SPI) = 1.68 Positive cost variance implies that we are efficient in accomplishing the scheduled work, i.e. costs are running under budget Cost Performance Index (CPI) = 1.14

107 Armin Busse [email protected] CXI Summary

To Do list Design Instrument Stand for the 1 micron Sample Chamber (dependent also on the Detector Stage interface) Develop detailed solutions from the preliminary design Develop an alignment plan Design ready to advance to final design
