Attendees: Will, Rebecca, Alex, Eliazar
Discussion:
- Bender ESD in review
- Working on FDR slides
- FDR Date? Before end Feb?
- Goal is to complete slides this week.
- Review committee: Lance Lee, Bob Baker, Lin Zhang, Matt Church
- build to print system (any external interfaces?-just one...in the chamber...documented in bender ESD, chamber ESD, and in reference drawing)
- system design plan - complete? Will has template.
---
- multiplex - just check pitch range? - of chamber
- check lance's trace
- how can system accommodate both beams
- RP follow-ups?
- si reflections?
- matt to verify Lin's calculations
- engineering note
- coating damage
- Far Hall config. - where does this requirement go? MFX instrument PRD??? Or KB mirror PRD???
- PRD R2 in draft - see additions and provide feedback
- Wednesday meeting for safety requirements
- Lin software?

- extension into mec - mirror should be configured to allow for this
- we will need to make sure chamber has appropriate shielding. note from CXI study: https://slac.sharepoint.com/sites/ESH/rp/rpg/RPG%20Documents/Forms/AllItems.aspx?viewpath=%2Fsites%2FESH%2Frp%2Frpg%2FRPG%20Documents%2FForms%2FAllItems%2Easpx&id=%2Fsites%2FESH%2Frp%2Frpg%2FRPG%20Documents%2FRP%2DRPG%2D211130%2DMEM%2D01%2Epdf&parent=%2Fsites%2FESH%2Frp%2Frpg%2FRPG%20Documents
- Design Progress
- Chiller details (need to find space)
- Thermal enclosures - need to add requirements to chamber ESD - active enclosure ($$)
- mirror requires air outside of chamber to be stable to +/-.5C (+/-.1 inside) - numbers from Matt Seaberg- engineering note? where does worst case come from?
- Old Data from MFX - MFX fluctuates by ~5 deg during experiments
- New sensor data?
- controls requirements?
- RDS requirements?
- temp requirements - updated in ESD
- envelope requirements - updated in ESD??
- mirror requires air outside of chamber to be stable to +/-.5C (+/-.1 inside) - numbers from Matt Seaberg- engineering note? where does worst case come from?
- Chamber Interface and Envelope - horiz. complete; vert almost done.
- Randy is working on mechanical interface; working on cooling
- Chiller details (need to find space)
- PRD updates - separate sections (MFX, CXI, nanoCXI) https://slac.sharepoint.com/:w:/r/sites/lcls/lcls-2-he/wd/PRD/LCLSII-HE-1.4-PR-0294.docx?d=w782e6d430b214d399d44ee9d041b46e3&csf=1&web=1&e=ValzfM
Need a decision about where to put bypass requirement- New requirement added - needs review then can go for sig.
can we review this? Leland! Alex!stabilitycoatings- how many stripes, how big?, material; (current is B4C 14mm; Rh 6mm; no thickness specified - 50nm?)reflectivity specificationref. map (will can provide)
energy range
- ESD Progress
- Bender -
- Progress 70%
- New ESD and FDR material(Mirror, bender, actuator, chamber) for Bender. Documentation from L2SI not existing. Number and Title?
- some analysis needed
- ESD - a month of work?
- models and drawing are near FDR level ~90%
- undocumented analyses - should these be redone? who did this before? Danny and Lin? Only have CDR level stuff.
- measurements of existing system - we have some metrology
- do we have records of old requisitions? maybe those point to some other documentation...Eliazar may be able to help there (procurement team help)
In house procurement so drawings will serve as the document?- Engineering note explaining analysis and design choices + drawings? (will also need assembly traveller later) ; to supplement existing L2SI documentation?? ask May Ling
- complete by end oct - driving review date
- Chamber - ESD in work 99% -in review with Bob
- Bob Baker and Jean Pierre have been reviewing
- procurement - expected lead time 20months?
- motion table in work - supporting doc
- Will will upload - on working doc site
- Mirror/Coating - ESD in work 99% -in review with Bob
- will be combined with CXI
- Need drawings and profiles for CXI
- procurement - expected lead time 20months?
- Bender -
- large displacement mirrors (in plan for DXS, CXI) - but not in plan for original MFX - need to specify this feature if we need it (also impacts radiation safety, exit flanges?, etc - other impacts to be consider)
- Schedule - next milestones
- SOW Chamber - 90%
- SOW Substrates - 40%
- Reviews:
- (1)FDR Bender Systems- February 15th
- common to CXI, DXS, MFX
- review prep: reviewers (SLAC internal)
- indico site
- (2)MFX Optics System FDR/TPRR end of March?
- chamber, actuator, substrates
- SOW
- (3) DXS separate review March?
- (4) CXI separate review April?
- (1)FDR Bender Systems- February 15th
