Development of a Flexible Trigger System for FAIR — •Manuel Penschuck1, Jan Michel1, Joachim Stroth1, and Michael Traxler2 — 1Goethe-Universität, Frankfurt — 2GSI Gesellschaft für Schwerionenforschung, Darmstadt
In the scope of experimental set-ups for the upcoming FAIR experiments, a general purpose trigger and read-out board (TRB3) has been developed which is already in use in several detector set-ups. For on- and off-board communication between the DAQ’s subsystems, TrbNet, a specialized high-speed, low-latency network protocol developed for the DAQ system of the HADES detector, is used. Communication with any computer infrastructure is provided by Gigabit Ethernet.
The TRB3 can be operated as a stand-alone board for small detectors, in combination with other TrbNet-enabled frontends, or as a subsystem of an existing DAQ infrastructure. In order to support these different scenarios, a flexible and modular central trigger system was developed. Trigger criteria can range from basic trigger strobes, internal pulser signals to complex data streams from other, foreign trigger systems. Additional features include detection of coincidence from several input signals with adjustable time delays and windows. A precise time information of all input signals with 20 ps precision is foreseen in the design.
In this contribution the design of the new trigger system and its web-based control and monitoring tools will be presented.
