Production Readiness Review:

  • We will have the Production Readiness Review for the VPTT subunits on Friday 14th of this month:
    • The technical coordinators Lars and Tassos and external expert Herbert Loehner will do the review
    • The agenda comprises talks from Bochum and Bonn colleagues
    • Barrel colleagues Hans and Markus will also attend


  • Backplane: design work not yet finished
  • Cabling to backplane forseen similar as on SADC: Pitch-adapter plus connector (Christoph)
  • Basically 1:1 feed throughs
  • No sophisticatd cabling with respect to load distribution necessary, instead 1:1 cabling
  • Power supplies will sit on separate PCBs, not directlt on backplate (distance form the DC/DC converters to signal lines)


  • 2 SFPs irradiated at KVI with 6*10^10 protons per cm^2 fluence
  • Standard SFPs fully satisfying for PANDA phase 1
  • Versatile Links replacing standard SFPs after phase 1 (or from the beginning if possible)
  • Versatile Link irradiation beam time at KVI in September


  • Decided to buy Stycast 1266 cryo epoxy and test it for suitability (wrt to viscosity) for insert to alveole glueing

APD preamps:

  • About 300 pieces currently under test in Basel
  • Wait for a larger batch to ship to Bochum (no need to have it there now) -- ThomasHeld - 13 Jul 2017
