30TH INTERNATIONAL COSMIC RAY CONFERENCE Characteristics and Performances of the electronics for the fluorescence detectors of the Telescope Array experiment

Abstract: The three stations of the Telescope Array fluorescence detectors(FDs) contain 12 telescopes each, and each of the telescopes has a 256 pixel PMT camera with a field of view of 18 ◦ × 15.6◦. The fluorescence signals of each pixel are digitized with their waveforms by the Signal Digitizer and Finder(SDF) modules. The results of signal finding from the SDFs are sent to the Track Finder(TF) module to fine air shower tracks. When a shower track image is found in the field of view, the Central Trigger Distributor(CTD) module sends the final trigger signal to all the telescopes to store their data. Here we will describe the characteristic features and performances of the electronics, which are developed and measured through laboratory tests and actual fluorescence light measurements
