2021-01-12 Detector Planning Meeting notes

• No experiments until Saturday 1/30

• Detector readiness:
  • Monitor 2m repairs at TID
  • Monitor quad repairs at TID (one quad returned)
  • Send 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 -Late April
    • SparkPix-S Phase II (full-size ASIC for sparsification, Tixel-based) PEC today
    • ePixHR IV:  Prototype detector
    • TXI Detectors (2Mp and 140kp based on ePixHR @5kHz) CDR tmw
    • ePixUHR (130nm TSV structure to reach 100kHz)
  • Production:
    • spare modules (0.5 & 1mm) Module order in work
    • Proposed 3d copy of ePix10k2m (pending)
    • Proposed spare quads for MEC (2)
    • Proposed in-vac ePix10k2m for CXI
    • Proposed UED detector upgrade (2kHz, 125um sensor)
  • RIXS-CCD/cooler test and verification.
  • 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.
    • 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
      • LCLS I/II compatibility
    • Table seismic
    • BIO for racks in chase
    • DP node purchase

Actions:

• Case surge anticipated in January, extra absence. All hands update coming.
• Avoid being at lab first two weeks of Jan. One person per day?
• Focus on remote data analysis as possible.

CH: 

• Conference last week, uploaded some talks
• Meeting w/Chris Iniewski, RAL folks.

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:

• ePix100 scan for use in run18...Diling has preferences.
• HV cables done, re-install @CXI.  Matt found defect in a fiber feedthrough.
• CXI ePix ran fine in ASC over the weekend.
• Grabbing JF modules for test in lab, but need power supply board from PSI.
• IOC

PH:

• MEC deployment, can't read back data from one quad.
• Circular connectors tough to release...special tool?
• EMP shielding for in-vac cables isn't tight at connector...revise?
• UXI IoC update.
• w/Bhavna & Frederic regarding commissioning data.

BN:

• Got code working, now need to le it run on some data....
• Lab visit week of thanksgiving, January moving.

Thursday updates:

PH

• UXI
• One quad at MEC had wrong event code, set in expert panel edit traveler for event codes
• Working to understand LV44 data…looks like photons are causing the ‘spikes’ in fourier space

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

• Bhavna JSA
• BIO for move
• Arranging setup lab
• move mobile rack o XPP alcove

Coordinate/update lab schedule.
