Overview of Trigger Configurations and Data Flow in IceCube and IceTop Projects

This document outlines the philosophy and configurations related to trigger systems in the IceCube and IceTop experiments. It details the deployment strategies for various triggers, including InIce and IceTop, and emphasizes the need for robust monitoring and data logging. The summary includes numerous tables describing different trigger types, sub-trigger configurations, and the processes needed to optimize data flow and capture critical event data. The guide aims to enhance understanding of time windows and ensure data quality in the experiments.

Presentation Transcript

  1. D. Seckel, Univ. of Delaware

  2. Outline • Philosophy • Table • More tables • Still more tables (blame Pat) • Summary (Table of tables)

  3. Philosophy • InIce and IceTop Triggers should configure at deployment • Drop in trigger classes • Hints to GT to allow appropriate time window extention • Robust to data interruptions

  4. Monitoring Logging Shower Trigger 4-fold, 10 ms H. Sh. Trigger 5-fold, 100 ns + SF Calibration IDH IDH IDH IDH IDH IDH IDH IDH IDH IDH Data flow through IIT Drop in sub-trigger w/payload scanner and beacon. DAQ control Global Trigger splice Joiner splice - Timestamp and Latency scanner - “Payload” scanner and router • “Beacons” maintain • output frequency

  5. Deployment actions for XXX • Deploy Trigger Module-XXX • Acquire “XXX-config ID” • Acquire List of Subtriggers • Deploy subtriggers • Acquire “subtrigger config ID” • Create subtrigger object • Create scanner, beacon for subtrigger • Configure subtrigger • Create input scanners • Create output beacon • Configure XXX

  6. Trigger Types

  7. Table of trigger configurations

  8. SMT sub-trigger configurations

  9. Trigger Data Sources

  10. Readout Request

  11. Time Windows • D- D+ are instructions to GT • Time window is extended to capture early and late event data from other IceCube components • For example: InIce trigger with D-= -10000 enables capture of surfce data.

  12. MBT sub-trigger configurations

  13. Calibration sub-trigger configurations

  14. Data Quality Trigger • Needed to capture questionable data flagged by upstream timestamp and latency scanner. • Definition - TBD

  15. Summary • Lots of tables • Trigger Types • Table of trigger configurations • Tables of sub-trigger configurations • SMT sub-trigger configurations • MBT sub-trigger configurations • Calibration sub-trigger configurations • Data quality sub-trigger configurations • Shower trigger sub-trigger configurations • Data source & Readout types
