NOvA DDT (Data Driven Trigger) Wiki¶

This page contains information on the trigger systems for the NOvA experiment. These pages document how to develop, test, characterize and deploy triggers for the detectors. If you have questions, please contact Andrew Norman (anorman@fnal.gov) or Martin Frank (mjf8u@virginia.edu).

Operations and Shifter Instructions¶

Go here if you have operational problems with triggers running on the detectors.

• DDT On-Call Expert

These pages contain general information regarding how to interact with the trigger system.

• Shifter Instructions
• DDT Monitoring

Trigger Rate, Bandwidth and Allocations Tables¶

These pages contain the up to date mappings of the triggers that are run on the NOvA detectors along with allocated bandwidths, prescales and other values affecting the allocation of DAQ/Trigger resources.

Current Tables (21NOV2014): (Verify tables up to dates, esp. rates - NJB)

• Trigger Rates
• Trigger Assignments
• Bandwidth Allocation

• Adding and Updating Triggers

Expert Instructions¶

• Testing a new Configuration FHICL
• Updating the Configuration FHICL
• Updating the UPS Product
• Building DDT product for novasoft
• Rogue DDT Processes
• Overriding the startDDTFilter parameters with ddt-operations.cfg

Software Development¶

Instructions for getting started and working with the trigger software frameworks.

• Trigger Development

Trigger Algorithms¶

These pages contain information regarding specific triggers in the Nova system.

Physics

• Muon Neutrino Trigger
• Upward going Muon Trigger
• Monopole Triggers (Slow and Fast)
• Total Energy Triggers
• Moon and Sun Shadow Trigger
• Neutron-Antineutron Oscillation Trigger

Calibration

• Activity_Triggers
• Calibration Triggers
• Stopping Muon Triggers

Data Samples¶

All data collected by the Nova DAQ is split into different "streams" corresponding to the type of information that is being collected (physics processes, calibration, etc...)

Zero Bias (Needs updating - link broken - NJB)¶

Zero Bias samples are collected as part of the normal readout. Information on how to use zero bias data:
Locating Zero Bias Data

Triggered Data (Needs updating - link broken - NJB)¶

Data taken with NOvA are cataloged via the SAM system.

Locating Data

Some small samples of (legacy) data can be found at /nova/ana/trigger/data
