10 minBeamtime support update
  • Detector readiness:
    • Return ePix100#7 for repair?
    • Receive/test ePix100 spares and side-look 1mm ePix10k
    • Baseline JF and 2M 'traveller' pages on Confluence.
      • Collect and analyze any remaining in-lab test data.
30 minPriorities ReviewAll
  • 2021 events:
    • Projects new starts:
      • VFCCD/ePixM downselect → implementation of REXS for 2.2 - April 28-30
        • Panel charge draft finalized, panel set, website set up. 
      • SparkPix-S Phase II (full-size ASIC for sparsification, Tixel-based, underway)
      • ePixHR IV:  Prototype detector project underway
      • TXI Detectors (2Mp and 140kp based on ePixHR @5kHz) CDR Closed out, project underway.
      • ePixUHR (130nm TSV structure to reach 100kHz), planning
    • Production:
      • spare modules (0.5 & 1mm) Module order in work, new sensor order out
      • Approved 3d copy of ePix10k2m: PA code issued, work begins
      • Approved spare quads for MEC:  PA Code issued, work begins
      • Proposed in-vac ePix10k2m for CXI:  Need FY21 cost split, likely to go forward
      • Proposed ePix10k4m (concept)
      • Proposed UED detector upgrade (2kHz, 125um sensor)
    • RIXS-CCD/cooler test and verification (cooler and packaged supply tested at STA).  Engineering note released.
    • HiZ collaboration tests (IH secured, plans circulated to collaboration partners), met w/SSRL, LoI needed
    • Outreach for R&D support (SparkPix-ED, SparkPix Delta).
    • Support effort for LCLS-II-HE instruments (performance verification/implementation planning)
    • SBIR effort for UXI.


  • Group priorities review:
    • Testing
      • Setup ePix10k, ePix100, JF smalls for test in lab, Bhavna/Chris hands-on trng.  Day this week?
      • Review with TID the stitching progress, look for improvements.  Stand up calibration team
      • Can we figure out what's wrong with ePix100/7?
      • RIXS-CCD cooler test planning. 
    • Analysis
      • Gather and process relevant commissioning data for Mp travellers on Confluence.
          • Solid pedestals
          • Noise map
          • Response uniformity (mini-X cu-fluorescence)
          • Bootstrap gain (sealed source)
          • Linearity (signal injection)
    • Documentation
      • Complete on-line travellers for Mp detectors

    • Development
      • RIXS-CCD, review engineering note with w/NEH 2.2 
      • SXR Downselect prep.  May 1?

    • Lab 'commissioning'
      • DAQ
        • Storage nodes received
        • LCLS I/II compatibility?
      • BIO for racks in chase (Chris to take over hounding)
      • Vac chamber for in-lab tests?  Compatible with XPP alcove?

Issues with UED pedestals/corrections

Cal status summary pls, 


CH: 

  • ePix10k #1 has been tested, looks ok
  • pyROOT for per-pixel spectra
  • Synchrotron.

RA: 

  • Meeting w/PD tmrw, camera.
  • Need bake-out variac for lab.

KN:

  • Rayonix still cranky trigger, may be DAQ-related
  • Spare JF Power supply received, need cold plate.
  • UED MPOD?
  • Rayonix has two bad tiles, too close to experiment to fix.

PH:

  • MFX 10k calibration with hockey stick has been refined slightly..2% of pixels have noisy first switch, need more uptime to test.
  • UXI IoC update, need help from Dan to run in the lab.


BN:

  • Made updates to detector website, in work.
  • working with PH on porting PyRoot to Python.


CK:

  • Ge chamber assembly
  • Order variac
  • New pin-out probes
  • XPP having trouble with pgp server hat runs 2M.
  • CXI fiber 450uW becomes 50-60uW, defect in port feedthrough sometime limits to 2uW(?), replacement flanges on order (8-9 weeks).
