2021-02-09 Detector Planning Meeting notes

• Covered in Monday's meeting, Chris to take over from Kayla
• Detector readiness:
  • 2m.1 back at MFX
  • Quads back at MEC
  • New HV module received....return ASC unit to XCS?
  • ReturnePix100#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
    • SparkPix-S Phase II (full-size ASIC for sparsification, Tixel-based) Has passed PEC
    • ePixHR IV:  Prototype detector
    • TXI Detectors (2Mp and 140kp based on ePixHR @5kHz) CDR Closed out.
    • ePixUHR (130nm TSV structure to reach 100kHz)
  • Production:
    • spare modules (0.5 & 1mm) Module order in work, new sensor order out
    • Proposed 3d copy of ePix10k2m (pending)
    • Proposed spare quads for MEC (2)
    • Proposed in-vac ePix10k2m for CXI
    • Proposed ePix10k4m
    • Proposed UED detector upgrade (2kHz, 125um sensor)
  • RIXS-CCD/cooler test and verification (ship archon and cooler supply to STA)
  • HiZ collaboration tests.
  • 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
    • Review with TID the stitching progress, look for improvements (meeting 2/10)
    • Can we figure out what's wrong with ePix100/7?
    • RIXS-CCD cooler test/ship plan
  • 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)

Actions:

CH: 

• Ran Quad 1 at different biases.  Working analysis.
• Pedestal scripts not working since last last update.  Need Silke's help.  Permissions issue?
• Need function to pull spectrum (histogram) for each pixel.
• MPOD messes up above 200V, goes higher than programmed.

RA: 

• Meet re cooling concepts...met with Jim re outside space: not much.

KP: JSA summary list circulated

• XPP/MFX/XCS fibers due this week, other wise need ugly solution.
• Small Rayonix testing can be done by others.
• XPP/XCS power cable pinout (controls needs to tell us MPOD working)

KN:

• Spare JF Power supply received.
• Seb looking for low-intensity diode.
• UED MPOD?
• Rayonix pressure issue manifold replaced, refilled, monitoring.

PH:

• Lent light meter to MEC to test feedthrough.
• MEC working new cables to improve grounding.
• Circular connectors tough to release...special tool?
• EMP shielding for in-vac cables isn't tight at connector...revise?
• UXI IoC update.

BN:

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

KN

• 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).

CH

• Measurements on sm 10k, pedestal application inconsistent in online ami, raw data is fine.
• Still see dashed lines in pedestal config.

KP

• RMA for MPODs
• Lab cleaning tonight.

Coordinate/update lab schedule.
