2019-06-17 Detector Planning Meeting notes

Single 90 min meeting going forward, rather than two 60min meetings?

• Dr. Conny Hansson is here to interview Friday. Please have your questions ready, this is your chance....
• Development Program: had been looking at an overrun, now looking at an underrun of few hundred $k.
  • Primary causes: Late start to VFCCD (PEC tmrw), slow charging on TES, no response from UCB-SSL.
  • We'll lose any underrun and have to take it out of FY20. Only avenue is to pull FY20 spending forward, but that's a challenge.
  • Development options under consideration:
    • Tixel: Design sparse readout architecture ($100k).
    • ePix: Design shingled high-rate camera ($100k)
    • ePixS: Build small camera for use in Run 18 ($75k)
    • ePixHR2.5D matrix: Design and fab wafers ($180k)
    • ePix10k 2MV (vacuum) parts: $100k)
  • Ops spending to consider:
    • 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:

• • Sensor wafers for 10k big have finally arived and been sent out for bump bonding. This is critical path, so parallel flip-chip run has been added.
  • Testing ePixHR: ASIC tops out at 4kHz. Suspect another iteration will be necessary to get to 5kHz. This is perhaps the fastest x-ray backend to date? Tests continue.
  • Working on ReBaseline of ePixHR with transition from Phase III to Phase IV.

• SXR requirements doc signed off by Peter, and Angelo, released to BES for reference.

• TES re-baseline document has been posted to sharepoint and released to LCLS Management.

• Project document for MCP/TImepixcan't be funded through LBNL, so overhead added.. Need to get funding rolling, slow response from UCB.
• Need to conclude the fiber saga.....collect items from Ernesto and TID (timing crate)? (do fibers run from detector lab to laser lab??)
• Status of 'buy' list?
• Let's do electric out of the remaining M&S budget on 16159 if it's all M&S

Status:

• RA: 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: SDD detector running in lab....ready for egun testing
• EMP testing confusing, but 10k didn't fall over. SIlke and Mike Brown helping.....
  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: Wave8 for FIM ?? Review conducted....small action list, seems on track.
• Laser setup done except training.
• KZ: Draft RIXS CCD procedure completed.
  ePix10k requires new MPODS, working issue
• Laser SoP moving forward...set up so no laser glasses necessary...administrative controls OK
• 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: 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
