2021-03-09 Detector Planning Meeting notes

• Chris has taken over Mondays, all in order for next two weeks pending changes.
• 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.

• 2021 events:
  • Projects new starts:
    • VFCCD/ePixM downselect → implementation of REXS for 2.2 - April 28
      • Teams briefed on downselect plan.
      • Panel charge draft in circulation, review w/Kai&Co. 
    • 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 (planning) - cost delta may delay
    • Approved spare quads for MEC (planning) - same cost delta may delay
    • Proposed in-vac ePix10k2m for CXI
    • Proposed ePix10k4m
    • Proposed UED detector upgrade (2kHz, 125um sensor)
  • RIXS-CCD/cooler test and verification (cooler and packaged supply tested at STA).  Engineering note in signature process, review w/Georgi
  • 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 (ordered)
      • LCLS I/II compatibility
    • BIO for racks in chase (Chris to take over hounding)
    • Vac chamber for in-lab tests?  Compatible with XPP alcove?

Actions:

Vaccine available

Controls/PMPS seminar at 11am

Anton has MCPs, expects first tests with Timepix this week.

Issues with UED pedestals/corrections

RIXS hardware shipped to STA, packaged

Detector storage in NEH/setup lab??

Cal status summary pls, 

CH: 

• R0 measnurements run
• Slides for Hi-Z consortium
• Synchrotron.

RA: 

• Practice install JF modules on test mount.
• Notes on Slack page.
• Need working power supply before testing.

KN:

• 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.

KN

• UED guys are set with new cables
• ePix UED temp 63C
• Sunday MFX finishes, 2M comes off, box delivered to MFX today.
• 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).

Coordinate/update lab schedule.
