[CRI110] jNICHE: Prototype detectors of a non-imaging Cherenkov array at the TA site
The Telescope Array Low-energy Extension (TALE) experiment is a hybrid air shower detector for observation of air showers produced by very high energy cosmic rays above 10^16.5 eV. TALE is located at the Telescope Array (TA) experiment site in the western desert of Utah, USA. TALE has a surface detector (SD) array made up of 103 scintillation counters (40 with 400 m spacing, 36 with 600 m spacing and 27 with 1.2 km spacing) and a Fluorescence Detector (FD) station consisting of ten FD telescopes located at the Telescope Array Middle Drum FD station, which is made up of 14 telescopes. TALE-FD full operation started in 2013. The deployment of the 103 SDs was completed in March 2017, and to date about 70% of the array is in operation with a full triggering and DAQ system. Here we report an overview of the experiment, its capabilities and the technical details of the TALE SD trigger and DAQ system from 4 month's operation.
