2021-04-27 Detector Planning Meeting notes

• No JSA needed for Office work, welcome to come on site as comfortable, pls coordinate if you occupy shared office, cubicles etc.
• Run 18 lessons learnedPlease use next instrument/dept meeting to have a lessons learned discussion with staff, take notes, send to me
• What worked well?
• What we can do better?
• What is the recurring issues needing attention?
• What is most needed to make your job easier?
• What do you wish people would know that would make your work smoother?
• What do you wish you knew that would make your work smoother?

• 2021 events:
  • Projects new starts:
    • VFCCD/ePixM downselect → implementation of REXS for 2.2 - April 28-30
    • 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: underway, November delivery
    • Approved spare quads for MEC:  underway, August delivery
    • Proposed in-vac ePix10k2m for CXI:  Deferred in favor of in-air 2m/1mm
    • Proposed ePix10k4m (concept)
    • Proposed UED detector upgrade (2kHz, 125um sensor, concept)
  • RIXS-CCD/cooler test and verification:  Second cooler rec'd, ship to STA??
  • HiZ collaboration tests: SSRL LoI needed, Ge chamber 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
    • explore CompEn bit function on 10k
    • Setup ePix10k, ePix100, JF smalls for test in lab, Bhavna/Chris hands-on trng.  Days this week?
    • Review with TID the stitching progress, look for improvements.  Latest on switching noise?
    • 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
    
    
  • Lab 'commissioning'
    • DAQ
      
      • Storage nodes  configured, put in use?
      • LCLS I/II compatibility?
    • BIO for racks in chase: anchoring status?
    • Vac chamber for in-lab tests?  Compatible with XPP alcove?

Actions:

LDAC Panel assembled (waiting on Kuster) 

CH: 

• TXI mtg help.
• IFDEPS?
• pyROOT for per-pixel spectra
• Synchrotron NoI?
• Ge config?

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).

Coordinate/update lab schedule.
