Minutes of the Forward Endcap EMC SADC Crate Design Vibe/eZuce meeting, 4th of May 2020, 14:00-15:15

Presence:

  • Bochum: Tom, Matthias, Claudius, Fritz-Herbert, Malte, Miriam, Tobias H., Tobias T., Sebastian, Thorsten
  • Basel: -
  • Bonn: Christoph, Johannes
  • Groningen: -
  • Uppsala: Pawel
  • Giessen: Markus, Hans-Georg

Submodule Manufacturing:

  • 500 (Basel estimate) - 800 (Bochum count estimate) preamps missing
  • 300 uFL coax cabels still in Bonn, cut in half this is enough for 600 preamps (incl. spares this is closer to the Basel estimate of 500)
  • Still no exchange of submodules between Bonn and Bochum possible (no business travel for the time being)

Bonn Test Stands:

  • 'Right' test stand equipped with new EPICS control incl. HV boards
  • 'Left' test station for annealing LED cabling and I2C traffic noise tests
  • Johannes did several tests on I2C communication
  • Concerning annealing LED cabling noise we should meet in Bonn as soon as regulation and situation allows

Data Concentrators:

  • First data concentrator test PCB in production (estimated duration 3 months)

SADC Controller:

  • Microsemi FPGA alternative:
    • Good results with data retrieval
    • External PLL needed (less power consumption on controlle board)
    • Response: 200 ps jitter
    • Not so well described as Xilinx FPGA (somewhat black box)

APD Screening:

  • Ongoing at Strahlenzentrum Giessen
  • New batches for screening will be sent to Bochum

Personnel:

  • Markus Preston (Stockholm) finished his PhD thesis and will leave PANDA
  • However, he fortunately will go to Uppsala U and will be available for information about his work done for PANDA (feature extraction etc.)
