• Bonn: Christoph
• Groningen: Myroslav
• Stockholm: -
• Uppsala: -
• Giessen: Markus, Simon,
• GSI: -

Bonn-Bochum Parts Exchange:

• Miriam will make a trip to Bonn on Thurday to perform THMP measurements with the Bonn setup
• She will bring the last two repaired VPTT submodules and styrofoam boxes for (some of) the crystals still in Bonn
• She will carry the 'Hot Cutter' machine, the 8-Mountplates, ~360 stripped signal coax cables, drilled capsules (all of them except for 800 still to be machined)

SADC Crate Design:

• KVI (Rick) is still able to do (re)design work on the crates
• A current design change to allow for mounting of the backplane PCB is in progress
• A backplane PCB will be given to KVI by Pawel and the crate design refined accordingly
• Currently no third party needs to overtake work on the design, however, workshops in Bochum/Bonn may help if necessary to manufacture parts
• The cooling sidewalls are probably subject to redesign

Last Week's Juelich Beam Time:

• There was one week of beam time in Juelich last week to test the commen readout of STT and EMC components with TRBs, data concentrators
• EMC crystal readout divided into separate SADCs and data concetrators to check the combination
• Synchronization of all ADCs worked as expected
• Myroslav showed several plots of a first look into the data taken
• A timing resolution of 1.7 ns could be achieved

APD Screening:

• The upgrade of the irradiation at Strahlenzentrum Giessen to the new designed irradiation/shipping PCBs will be finished soon
• The 50 paired APDs for a new Barrel EMC prototype will be sent end of this week by Bochum colleagues
• APD pickup at GSI is planned for Friday this week
