APD-Submodules:

• Johannes presented a software that allows to display the SADC channel as scope screens. With the two APD submodules read out noise pickups in the high gain channels of the "blue" APDs (that are the ones mounted closest to the annealing LEDs) show up.
• Christoph will check the LED cabling which is currently set up as foreseen in the forward endcap later on: Shielded cables up to the forward endcap aluminum housing (here: the fridge housing) and unshielded cabling inside the housing.
• It may turn out that shielded cabling is also needed inside.

SADC-Crates:

• Pawel received the irradiated, failing power supplies from KVI. A detailed check of what component(s) failed will follow.
• The situation of SADC redesign work at KVI is unclear, sent query to Myroslav.
