The ATLAS Event Builder
/ Vandelli, W ; Abolins, M ; Battaglia, A ; Beck, H P ; Blair, R ; Bogaerts, A ; Bosman, M ; Ciobotaru, M ; Cranfield, R ; Crone, G et al.
Event data from proton-proton collisions at the LHC will be selected by the ATLAS experiment in a three-level trigger system, which, at its first two trigger levels (LVL1+LVL2), reduces the initial bunch crossing rate of 40~MHz to $sim$3~kHz. [...]
