The purpose of this talk is to present the general features of the Trigger Framework
and its associated components in a tutorial presentation. This is done by showing the
functions of the Trigger Framework from the viewpoint of a number of different systems.
TFW Tutorial Outline• DAQ Context and Beam Structure in Run II:
– Current Run II Beam Structure and Slang Terms– DAQ System Buffering
• Scope of the System, Physical Location, Hardware Implementation– Location in MCH– Basic Cards in the Trigger Framework
• Level 1 Functions of the Trigger Framework– Location of the Trigger Framework in making the Level 1 Trigger Decision– Simplified block diagram of the Trigger Framework L1 Decision logic
• Level 2 Functions of the Trigger Framework– Information to and from the L2 Global Stage– Simplified view of issuing the L2 Trigger Decisions
• Routing Master Function of the Trigger Framework– Trigger Framework Information to the Routing Master
TFW Tutorial Outline (continued)• Readout to Level 3 Function of the Trigger Framework
– Trigger Framework Readout to a standard VRB crate– Block Diagram of a standard VRB crate.
• Trigger Control Computer Connections to the Trigger Framework– Block Diagram of the Trigger Control Computer Connections to the Trigger
Framework– Function of and data carried on these connections– Example of Commands from COOR
• Scalers and Monitoring Functions of the Trigger Framework– Sources of Monitoring Information– Trigger Monitoring and Luminosity Monitoring– Trigger Operation Monitoring vs Physics Analysis Monitoring– Content of the Monitoring Information
• Initialize and Cold Start of the Trigger Framework– What happens at Trigger Framework Initialize– Cold Start of the Trigger Framework and associated hardware
