2019-08-06 Detector Planning Meeting notes

• Hansson: met with Gunther, Angelo, Mike, David, Bill yesterday, very positive. I expect we'll make him an offer, and we'll see what happens. Visa issues may be a problem.
• RIXS-CCD Acceptance Package submitted. Thanks to all. Next step is ICD, but NEH2.2 must decide on implementation.
• LDAC now 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:
    • 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:
    • ePix dummy bond to Ge to test method and thermal ($70k)
    • 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:

• • ePix development now transitioned to Phase IV (5kHz, TSV design)
  • 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: Workin got update milestone list.
• Looking at internal temp of airbox and sensor coldplate....agreed that 30C for the hottest pixel is the temp requirement.
• Need to use 700W chiller for JF4M
• BIO done. Ready to anchor legs. Tech not available
• Change request to 15mm 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
• UXI options?
• Need fewer photons in RIXS SSRL tests.
• 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.
  Omar says no CDS netwrok with fibers...true?
• RIXS-CCD report can be done by 6/30
  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 giving only 1.7 mW (should be 20mW)...talking to piqoquant about it.
• KZ: Draft RIXS CCD procedure completed.
  ePix10k requires new MPODS, working issue
• eGun interlock doc (2wk.)
• Status documentation/procedures effort
• How many fibers do we have to run to B84?? Work with Jana to tell Mark Foster (2wk)
  
  
• KZ: Tied up with FEE for next two weeks. Anchors to go in tomorrow
• RIXS-CCD Procedure draft complete. Review at next detector meeting??
• RIXS-CCD setup work
• Toolbox organization/reorder scheme.
• Consumables supplies received.
• Can't get dessicator or table legs anchored due to tech availability.
• Move guest chamber and stand into lab with riggers help
