Description
Ashra-1 is an optical-telescope based detector system optimized to detect VHE particles aiming for "multi-particle astronomy." The unit telescope is distinguished by two features: (1) an ultra wide angle optics with 42-degree FOV (field of view) compromising with high imaging resolution of 3-arcmin; (2) advanced combined simultaneous trigger system both for Cherenkov and fluorescence air-shower light. Based on achievements from Ashra-1, we are forming a new collaboration for realizing the next generation large Neutrino Telescope Array (NTA). A large array of high resolution imaging atmospheric Cherenkov and fluorescence telescope for survey of air-showers from cosmic tau neutrinos in PeV-EeV and gamma-rays in TeV-EeV; Ashra/NTA is expected to be plausible toward exploring PeV-EeV universe for cosmic ray origins and test fundamental physics using the "PeV-EeV universe laboratory". Note that NTA can distinctively enjoy the good sensitivity for gamma-rays in the high and wide energy range with the high point-back resolution much better than 0.2 deg, which is essential for identifying gamma-rays against background CR hadrons, using the unique and advanced combined simultaneous trigger system of air-shower Cherenkov and fluorescence light.
