Level-1 Trigger:
The Muon Trigger

Trigger
Dataflow:
The Level-1 Muon Trigger provides the fast trigger signals needed for the ATLAS Level 1 trigger decision, based on the number and transverse momentum of muon tracks in each event. The system consists of a Barrel section and two Endcap sections.
The The Endcap Level 1 Muon Trigger system utilises Thin Gap Chambers (TGC) to cover the region of small angles with respect to the beam axis with dedicated chambers fast enough to provide the Level 1 trigger information.
The The Barrel Level 1 Muon Trigger system utilises Resistive Plate Chambers (RPC) to cover the central region of ATLAS with dedicated chambers fast enough to provide the Level 1 trigger information.
The Muon Trigger to Central Trigger Processor Interface (MUCTPI) forms the interface between the sector logic of the muon trigger chambers and the Central Trigger Processor. It resolves overlaps between chamber sectors in the barrel and between barrel and endcap chambers and forms the muon candidate multiplicities for the trigger decision.
