2019-08-12 Detector Planning Meeting notes

• Hansson: working vias issues, hoping to make an offer.
• Meeting tomorrow 9am to discuss TMO science Neds as regards Tixel.
• LDAC set for Dec. 3-4.
  
  • Status of 2018 recommendations: 18 closed/complete, 13 in work/on track, 3 defered/rejected (Doc available).
  • NEED:
    • RIXS-CCD need analysis of flux limitations
    • 'White paper' on zeo-suppression tradeoffs.
    • Data analysis on ePix prototypes tested in Run 17.
    • Presentation on Jungfau 4M??

• Development Program: had been looking at an overrun, now looking at an underrun of few hundred $k.
  
  • Development options green-lighted:
    • Purchased new Cd rad source for testing ePix platform
    • OK'd outside testing of ePix to ~10krad
    • ePix dummy bond to Ge to test method and thermal ($70k)
    • ePixHi-Z cold testing ($70k)
    • Purchase of CZT material from Redlen ($15k)
    • Tixel: Design sparse readout architecture ($100k).
    • ePix: Design shingled high-rate camera ($100k)
    • SXR microwave annealing machine ($60k)
    • Want to add more BUT need to determine that existing work is on track at TID (ePix10k camera manufacture is slow)
      
      
  • Ops spending to consider:
    • ePixS: Build small camera for use in Run 18 ($75k)
    • ePixHR2.5D matrix: Design and fab wafers ($180k)
    • ePix10k 2MV (vacuum) parts: $100k)
    • Interlocks for GSFC x-ray source ($15k)
    • ePix100 additional spare modules ($24k)
    • $3k for metrology of existing ePixBig (FY19)
    • $25k to formally release ePixBig drawings/models in TeamCenter (FY20).

ePix Update:

• • ePix10k engineering unit being sent to APS for evaluation there. Can we get MMPAD here??

• Chase elex update
• Need to conclude the fiber saga.....timing fiber, and whee does the ATCA crate go??
• Status of 'buy' list?

Status:

• RA: Vacuum issues distracting. Mark ti check w/CXI..
• Need to use 700W chiller for JF4M
• Change request to 9mm central hole
• CXI stage can't handle CSPAD weight, crane overloaded, no obvious plan.
  
  JF is focus for foreseeable.
  Wavefront sensor work with Matt Seaburg.
  
  JF interface document development....where do we want to draw the line? MEC EMP testing CSPAD/ePix Date TBD

• PH: Wiring diagram for Jungfrau
• Need automated check on pedestal levels...Jason left and no one has picked up.....PH to follow up with Silke.
• UXI options? Nothing until next year....
• EMP testing confusing, CSPAD is shorted to ground....need to break that connection to do a fair comparison to ePix10k for troubleshooting purpose.
• CSPAD Quad given to TID for isolation/testing as next stage.
• Mike Brown has set up ePix10k and ePix100 on XCS for software development...not done?
  
  
  
• KN: Electrical work to be done by late August.
• Wave8 for FIM ?? Review conducted....small action list, seems on track.
• Laser laser returned by Picoquant..says no issues.
• KZ: Draft RIXS CCD procedure completed.
  ePix10k requires new MPODS, working issue
• Status documentation/procedures effort
  
  
• KZ:
• RIXS-CCD Procedure draft complete. Review at next detector meeting??
• RIXS-CCD setup work
• Toolbox organization/reorder scheme.
