Discussion:

- WFS impacts - would need to reconsider calcs
- RP impacts introduced to Shanjie last Monday
- what can we do to reduce design constraints?
- Diagnostic Station 1 in H4

- still require level 1 processing
- check mirror assumptions - pumping levels? outgassing?
- prelim pressure level at mirror chamber 7e-10torr (used to be 5e-10 - no formal requirement)
- adding apertures reduces to 6e-10
- shielding structure
- concepts under way
- requirements from RP - directing us to mirror shielding note
- need to translate into thicknesses for shielding
- preliminary vacuum analysis
- Common components
- vacuum chambers for PPMs etc is next large procurement
- Controls
- Antonio is leaving? Who will replace them?
- XRT - concerning for RP plan if layout changes, even on other beamlines
- CXI will not use KBs - so we will regain some real estate in the hutch
- Added scope for MFX?
- Future plans? It would be good to know so we can design with those in mind
- Documents:
- Instrument PRD - R2 open; added 2 new requieremnts
- Detector PRD out for signature? check progress? Stuck at Hong, Debarger
Detector PRD vs delivery plan - noise and well depth- are figures ok? is 10000photons @ 8keV ok (well depth)? noise <75e- vs <100 e-xpp hole will be 5mm - we can reuse guidance tube design (same as epix 10k)mfx assumption was we needed slightly larger hole? needed for laser?@ 450 mm away from IP, 5mm is a bit close.
- Detector ICD - out for review soon
- Detectors IRD in progress - Alex to look at
- ICD-Lasers
- Laser ESD?
- Laser Off-mods layout
- optics locations draft?
- optics categorization
- ATM tiles? need a final design?
- ejection layout
- IP
- LIC
- Diagnostic stand interfaces (breadboards)
- should attach to diagnostic stand?? not mods?
- need mods to stand?
- mount to floor instead?
- Laser Transport?
- Laser in coupling as designed should work as
- access on working site: https://slac.sharepoint.com/:w:/r/sites/lcls/lcls-2-he/wd/ICD/LCLS-II%20HE%20MFX%20Lasers%20ICD.docx?d=w73e52e9056f94e0cb9df481c8cd63f6d&csf=1&web=1&e=hJLtqF
