The Trigger System of the KLOE Experiment

Key Points

This research aims to detail the trigger system design for the KLOE experiment and evaluate its performance.
Designed a trigger system with first- and second-decision levels.
Utilized multiplicity of energy deposits in the calorimeter.
Analyzed hits in the drift chamber for selection criteria.
Evaluated detection efficiency using initial run data.
The trigger system effectively detects phi decays.
Evaluation showed high efficiency in identifying decay events during early runs.

Abstract

We present the design of the trigger system for the KLOE experiment at the Frascati phi-factory DAFNE. The detector consists of a large volume drift chamber and a calorimeter both immersed in a 0.52 T solenoidal field. The trigger, structured with a first- and a second-decision level, is based on multiplicity of energy deposits in the calorimeter and of hits in the drift chamber. The selection criteria are described and the efficiency for detecting phi decays are evaluated with the data collected during the first runs.
