• Bochum: Cathrina, Claudius, Malte, Matthias, Miriam, Tobias H., Tom
• Bonn: Christoph, Merlin
• Groningen: -
• Stockholm: -
• Uppsala: - Pawel
• Giessen: Hans, Markus
• GSI: -

APD preamp cabling:

• Christoph reported about the need for shorter cables (HV and signal) for the APD preamp wiring (compared to the cabling for VPTT preamps)
• News about the response distribution in the latest 16-crystal submodule earliest available at the end of the week

Data Concentrators:

• Pawel gave some overview of the work on the dataconcentartors build around Kintex UltraScale + FPGAs

SADC crates:

• Pawel presemted CAD drawings of the SADC crates, especially the backplane region
• There are two power supplies at the outer sides of the backplane in order to thermally connect to the crate cooling
• Currently the CAD drawings show existing power supplies as developed in Uppsala, they may be replaced by ones specifically designed for our needs
• Even the possible usage of CERNs rad-hard, B-Field compatible operation Feast power supplies was discussed:
  • Operation seems to be restricted to 11 V max. input, 5 V max. output, what would not satisfy our needs of 12 V supplied
  • However, Hans stated that the supplies are used to power MVD prototypes with higher voltages
