The ATLAS detector is designed to study the proton proton collision at the center of
mass energy of 14 TeV with the bunch crossing rate of 40 MHz. In order to reduce this
rate down to the level at which the events will be fully reconstructed, the
multi-level trigger system is being deployed. The level 1 (LVL1) trigger reduces the
rate down to 75 kHz via the custom-built electronics. The...

The ATLAS Level-1 Central Trigger consists of the Muon-to-Central-Trigger-
Processor Interface (MUCTPI), the Central Trigger Processor (CTP), and the
Timing, Trigger and Control (TTC) partitions of the sub-detectors. The MUCTPI
connects the output of the muon trigger system to the CTP. At every bunch
crossing it receives information on muon candidates from each of the 208 muon
trigger...

The level-1 calorimeter trigger is a hardware-based system with the goal of identifying
high-pt objects within an overall latency of 2.5us. It is composed of a preprocessor
system which digitises 7200 analogue input channels, determines the bunch-crossing of
the interaction and provides a fine timing and energy calibration; and two subsequent
digital
processors.
The Preprocessor plays...

The ATLAS first-level calorimeter trigger is a hardware-based system
designed to identify high-pt jets, electron/photon and tau candidates,
and to measure total and missing Et. The trigger consists of a
preprocessor system which digitises 7200 analogue inputs, and two
digital multi-crate processor systems which find jets, measure
energy sums, and identify localised energy deposits...

The ATLAS experiment uses a system of three concentric Resistive Plate Chambers (RPC) detector layers for the level-1 muon trigger in the air-core barrel toroid region. The algorithm looks for hit coincidences within different detector layers inside the programmed geometrical road which defines the transverse momentum cut. The on-detector electronics that provides the trigger and detector...
