The Trigger System

The trigger system contains the logic capable of making very fast decisions about when to acquire a physics or calibration event. These decisions are generally made using a small subset of the detector signals. Each experiment will, of necessity, design trigger electronics customized to that experiment. In order to simplify system integration, a common trigger interface, called the Trigger Supervisor, has been designed. For small systems or test setups, the Trigger Supervisor may be omitted.
