First Level Trigger for H 1 , using the latest FPGA generation

To cope with the higher luminosities after the HERA upgrade, H1 [1] builds a set of new MWPCs, which provide information to distinguish between beam background and trueep interactions. The first level trigger uses the latest 20K400 APEX FPGAs with 500 user IO pins to find tracks in 10’000 digital pad signals. It allows to reconstruct the event vertex and… CONTINUE READING
