30TH INTERNATIONAL COSMIC RAY CONFERENCE Data acquisition system of air fluorescence detectors for the Telescope Array exper- iment

Abstract

The construction of the fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been completed in June 2007, and the stereo observation have been started in June 2007. In this paper, we describe the development of the data acquisition (DAQ) system for the TA FD observations. The DAQ system of each TA FD station is comprised of 16 CPUs: 13 for controls of the FD front-end electronics and 1 for data storage and 1 for environment monitoring, and 1 for the central control of the whole system. We employ the Network Shared Memory system (NSM) for communication of the CPUs. We will present the detail of the system and the performance in the test observations and the first stereo observation.
