TDAQ WG - CERN L0 LKr trigger • Pixel based trigger processor (2x8 or 4x4 calorimeter cells tiles) • Low granularity readout independent from the full granularity readout • Fast readout after L0 for software triggers • Region of Interest for Lkr full granularity readout
TDAQ WG - CERN L0 LKr Trigger: architecture 13248 channels for the readout 864 channels (2x8 pixel supercells) for the trigger! FE boards: pulse reconstr (time, position, energy) Concentrator boards: merging, sorting • Three mezzanines: • LKr interface (to be designed in 2011 -> 2012) • Trigger & RO TX (custom link for the trigger + ethernet for the readout) – under test • Trigger RX (custom link for the trigger) – tested • Three 9U crates
