Discussion:
- Far Hall config. - where does this requirement go? MFX instrument PRD??? Or KB mirror PRD???
- general passthrough requirement in MFX PRD - Rebecca open revision to include new requirement
- enable "future passthrough of beam"
- https://slac.sharepoint.com/:p:/r/sites/lcls/lcls-2-he/exp/_layouts/15/Doc.aspx?sourcedoc=%7BBC0FC89A-A572-4FC7-AE30-B705270C528A%7D&file=MFX%20Endstations.pptx&action=edit&mobileredirect=true
- 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
- general passthrough requirement in MFX PRD - Rebecca open revision to include new requirement
- Design Progress
- Chamber Interface and Envelope - horiz. complete; vert almost done.
- Randy is working on mechanical interface; working on cooling
- Chamber Interface and Envelope - horiz. complete; vert almost done.
- 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
- Waiting for Meng but should be ready for review and signature?
- can we review this? Leland! Alex!
- stability
- coatings- how many stripes, how big?, material; (current is B4C 14mm; Rh 6mm; no thickness specified - 50nm?)
- reflectivity specification
- ref. map (will can provide)
- energy range
- ESD Progress
- Bender -
- New ESD and FDR material(Mirror, bender, actuator, chamber) for Bender. Documentation from L2SI not existing.
- 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
- New ESD and FDR material(Mirror, bender, actuator, chamber) for Bender. Documentation from L2SI not existing.
- Chamber - ESD in work 95% (-0900 MFX - not combined with CXI - Title?)
- procurement - expected lead time 20months?
- motion table in work - supporting doc
- Will will upload - on working doc site
- Mirror/Coating - ESD in work 95% (-0895 MFX - Title?)
- 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
- CXI KB FDR - 10/18 - more of a PDR , or push FDR
- SOW? - see
- MFX KB FDR?- plan is (Will will follow up)
- DXS Offset Mirrors FDR- 12/05/2023
- TPRR? (CXI vs MFX) - CXI might need an FDR review due to the focus scheme
- For MFX:
- FDR - End of January if Bender included
- SOW
- TPRR
- FDR - End of January if Bender included
