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 Tsolenoidal field. The trigger, structured with a first- and a second-decision level, is based on the 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 is evaluated using data.

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 Tsolenoidal field. The trigger, structured with a first- and a second-decision level, is based on the 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 is evaluated using data.File in questo prodotto:
