Outline of Final Research Achievements |
The TA Low energy Extension (TALE) SD array was completed in February 2018 with 80 surface detectors (SDs) at the Telescope Array (TA) site in Utah, U.S.A., in order to measure the energy spectrum, the anisotropy and the chemical composition of ultra high energy cosmic rays above 10 to 16th eV with high statistics, homogeneous detection efficiency and high accuracy based on stable and hybrid observations. The data acquisition system for the hybrid observations with the TALE fluorescence detectors (FDs) was completed in September 2018, and the hybrid observations have been continued. A set of data analysis programs were developed in parallel with the construction of the instrument. Results from TALE-FD monocular observations were published in 2018 and 2021, and preliminary results from hybrid observations were reported in 2021.
