VPTT Submodule Production:

• First cosmics test stand results from Bonn: The submodules testes so far are fine, showing maximum channel-wise variations in the +/- 20% regime, most of them in the +/- 10% regime
• Weekly delivery of submodules from Bonn to Bochum and package material in return works fine
• Mountplates for the 8 crystal submodules need to get a threaded hole (M3) for the ground pin, the Bonn workshop looks for the clamping tool for fixing the plates on the cnc machine
• New color codes for the cable bundling in the 8 crystal submodules were proposed
• There was some discussion (also after the meeting) and we finally agreed to build the 8 cystal submodules all in the same way, with identical crystal numberinmg from '8' to 'F' (instead of the former somewhat inconsitent '0' to '7' numbering) regardless of their later position on the backplate

SADC Crate Production:

• Rick Veenstar from KVI did the design which is basically finished
• The design is given to Pawel for the final design of the SADC backplane
• After validation a mock up backplane and a prototype SADC crate will be build (cooling tests, temperature monitoring etc.)
• Peter Schakel from KVI finally got a 4,8 Mbit/s link working (former rate was half of that)
