Abstract

The trigger used for the collection of the samples of K0 → π0π0decays in the NA48 experiment at CERN uses a novel pipeline design in order to satisfy the demanding specifications of a high rate kaon beam. The trigger algorithms, architecture and performance are described.

Funding

The neutral trigger is only one of a large number of subsystems which make up the NA48 experiment. It has been a great pleasure to work with our colleagues on the NA48 experiment, and we are most grateful for their help and advice. We would particularly like to thank the following CERN summer students who worked on the neutral trigger project: J. Anderson, K. Harder, G. Quirico. We are indebted to the Austrian Federal Ministry for Science and Transport for the financial support of this project (GZ 616.360/2-IV/6/95).
