摘要

HADES是德国达姆施塔特GSI SIS加速器设施中用于强子和重离子物理的第二代双轻子光谱仪。物理程序要求在具有几gb /s背景数据的环境中检测罕见事件。本文介绍了一种专用触发系统，该系统与一个流水线数据采集系统一起工作，可将背景事件抑制2个数量级。触发系统基于在fpga和dsp上实现的模式识别算法。

Pattern recognition in the HADES spectrometer: an application of FPGA technology in nuclear and particle physics

HADES is a second-generation dilepton spectrometer for hadron and heavy ion physics at the SIS Accelerator facility of GSI Darmstadt, Germany. The physics programme requires the detection of rare events in an environment of several GBytes/s of background data. This paper describes the dedicated trigger system which works together with a pipelined data acquisition system to suppress background events by 2 orders of magnitude. The trigger system is based on pattern recognition algorithms implemented in FPGAs and DSPs.
