Description

EUSO-TA is an on-ground telescope, located at the Telescope Array (TA) site in Black Rock Mesa, Utah, USA. The main aim of the instrument is the observation of Ultra-High Energy Cosmic Rays through detection of ultraviolet light generated by cosmic-ray air showers. EUSO-TA consists of two, 1 m2 Fresnel lenses with a field of view of about 11x11 degrees. Light is focused on the Photo Detector Module composed of 36 Hamamatsu multi-anode photomultipliers, for a total of 2304 channels. The telescope is housed in a shed located in front of the TA Fluorescence Detector. We present the results from 5 observational campaigns of EUSO-TA, including detected cosmic rays and meteors. Also shown are the studies done with dedicated artificial light sources, such as LEDs and lasers.
