ePix Update:

• • ePixHR:
  -         
  • • • Carrier PCB board required for testing the HR ASIC has been completed and is now in fab.
  -         
  • • • PCB will be back next week and we will bond the chips
  -         
  • • • Testing will start the week after
  -         
  • • • Mechanical housing of the HR camera (140k equivalent) will be complete in the next week and a half.

   

   
  • • • 
        
        
    • ePixM

     

    -         
    • • • Layout of ePixM LFoundry complete (3 variants full size)
    -         
    • • • Layout of test structures almost complete
    -         
    • • • Fabrication should start around the end of next week
        • Phase III was approved at PEC on Friday, re-planned to deliver working prototype for downselect vs. VFCCD in late 2020.

    • • Kickoff meeting for ePix fab April 3

        
        

    • Peter Denes visited last week

    •  

    • 1 in-air ePixBig (Jan 2020) and 4 thick-Si MEC (May 2020) quads also approved. Need a kickoff meeting and probably a little more hands-on than first article(?)

    • Peter Denes visiting tomorrow to discuss SXR imager requirements:
    • • • 50um pixel pitch
        •  15e- rms read noise
        • 5kHz frame rate or greater
        • 512x512-class pixel format, to be tileable to 1Mp-class with >90% fill factor.   Buildup from smaller 4-side buttable modules is acceptable. 
        • 1000 photon well capacity @1.5keV 530eV
        • >90% 70% QE at 277-1.5keV 
        • High Vacuum compatible (10e-9T)
        • Compatible with 2m electronics cabling and cooling hoses to allow in-chamber articulation.
        • Compact packaging for mounting within q-RIXS vacuum chamber (dimensions to be specified, but like iVFCCD concept))
        •  Visible-blind to laser pump background.
    • Decide ASC electrical after move-in costs known
    • Rebar scan complete, anchors set(?)....set up ASC coordination meeting (KZ)?
    • • • Peter wanted to express requirements rather than simple specifications. Document prepared and circulating for review. Comments by end of this week please.
    • TES re-baseline document has been prepared and is in review by LCLS. Will circulate for comment once strategy is agreed. Year 3 contract funding at CU turned on.
      
      
    • We have a costed proposal from Anton for MCP/TImepix tests...need to get this moving, may ask for some review comments.Status JF 4M effort. 4pm meeting today....
      
      
    • Update > Status RIXS-CCD test planning

• • Masks not here yet, checking with Sallie.
  • Ground issues resolved from first test?
  • Late March slips to mid-April??
  • Do first test at SSRL to decouple from ASC sked??

Status:

• MEC EMP testing CSPAD/ePix Date TBD
• PH gone first week April
• KN Wave8 upgrade for FIM CDR Mid-April
• ePix10k requires new MPODS, working issue
• Laser SoP moving forward...set up so no laser glasses necessary...administrative controls OK
• eGun interlock doc (2wk.)
• Lost cabinets were not delivered....(2wks)
• KZ: Control room furniture install this afternoon.
• Vacuum equipment moving today w/techs.
• Riggers set for Thursday 10am.
• Status documentation/procedures effort
• How many fibers do we have to run to B84?? Work with Jana to tell Mark Foster (2wk)
