The ICARUS Cosmic Ray Tagger Data Acquisition System

The ICARUS (Imaging Cosmic And Rare Underground Signals) experiment is nearing its time to begin taking data as the far detector at the Fermi National Accelerator Laboratory Short-Baseline Neutrino program. A vital subsystem of the experiment is the Cosmic Ray Tagger (CRT), which will provide necessary background rejection of cosmogenic events in the detector. The data acquisition (DAQ) system for the CRT must interface with the DAQ for the liquid argon Time Projection Chamber (TPC) and Photomultiplier Tube systems, that constitute the main neutrino detector, while maintaining precision in the relative timing for the three systems. Herein we discuss the plans for the CRT in order to ensure communication between the CRT and detector is effective and reliable.
