- ICD-1010 → capture scope changes - Rebecca this week
- 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.
