Minutes of the Forward Endcap EMC SADC Crate Design Vibe/eZuce meeting, 4th of May 2020, 14:00-15:15
Presence:
Bochum: Tom, Matthias, Claudius, Fritz-Herbert, Malte, Miriam, Tobias H., Tobias T., Sebastian, Thorsten
Basel: -
Bonn: Christoph, Johannes
Groningen: -
Uppsala: Pawel
Giessen: Markus, Hans-Georg
Submodule Manufacturing:
500 (Basel estimate) - 800 (Bochum count estimate) preamps missing
300 uFL coax cabels still in Bonn, cut in half this is enough for 600 preamps (incl. spares this is closer to the Basel estimate of 500)
Still no exchange of submodules between Bonn and Bochum possible (no business travel for the time being)
Bonn Test Stands:
'Right' test stand equipped with new EPICS control incl. HV boards
'Left' test station for annealing LED cabling and
I2C
traffic noise tests
Johannes did several tests on
I2C
communication
Concerning annealing LED cabling noise we should meet in Bonn as soon as regulation and situation allows
Data Concentrators:
First data concentrator test PCB in production (estimated duration 3 months)
SADC Controller:
Microsemi FPGA alternative:
Good results with data retrieval
External PLL needed (less power consumption on controlle board)
Response: 200 ps jitter
Not so well described as Xilinx FPGA (somewhat black box)
APD Screening:
Ongoing at Strahlenzentrum Giessen
New batches for screening will be sent to Bochum
Personnel:
Markus Preston (Stockholm) finished his
PhD
thesis and will leave PANDA
However, he fortunately will go to Uppsala U and will be available for information about his work done for PANDA (feature extraction etc.)
