VPTT Submodule Production:

• There was a discussion how to proceed in the vptt submodule restart of production
• Now, that the preamps gain of the already glued units is indirectly determined we should check whether the new component assignment leads to the neccessary and expected homogeneity in response within a submodule
• We there fore should wait for the latest optimization from Bonn and start with a subunit containg both dircetly and indirectly determined preamp gains and see if the result is as satisfying
• We need a solution for regular transportation of submodules from Bochum to Bonn

SADC Crate Backplane:

• There was a discussion where on the backplane pcb to place which connectors and the power supply
• Pawel explained, that an SFP connector and/or a versatile link would be desirable to have on the backplane pcb
• To what extend will the power supplies reach in the direction perpendicular to the backplane?

APD irradiation:

• The APDs that have been screened for the preparation of the PRR II meeting arrived in Giessen for a second irradiation session for diagnostics
