An Integrated Front-End Readout and Feature Extraction System for the BaBar Drift Chamber

J. Zhang
IEEE Nuclear Science Symposium Conference Record, 2005  
The BABAR experiment has been operating at SLAC's PEP-II asymmetric B-Factory since 1999. The accelerator has achieved more than three times its original design luminosity of 3 × 10 33 cm −2 s −1 , with plans for an additional factor of three in the next two years. To meet the experiment's performance requirements in the face of significantly higher trigger and background rates, the drift chamber's front-end readout system has been redesigned around the Xilinx Spartan 3 FPGA. The new system
