摘要
We describe the STAR Data Acquisition System. STAR is one of four experiments commissioned at the Relativistic Heavy Ion Collider (RHIC) at BNL in 1999 and 2000. DAQ combines custom VME-based receiver electronics with off-the-shelf computers in a parallel architecture interconnected with a Myrinet network. Events of size 80 MB are processed at input rates up to 100 Hz. Events are reduced to 10 MB by zero suppression performed in hardware using custom-designed ASICs. A Level 3 Trigger reconstructs tracks in real time and provides a physics-based filter to further reduce the sustained out put data rate to similar to 30 MB/s. Built events are sent via Gigabit Ethernet to the RHIC Computing Facility and stored to tape using HPSS. (C) 2002 Elsevier Science B.V. All rights reserved.
