EUSO-TA data and simulations — •Francesca Bisconti for the JEM-EUSO collaboration — Institut für Kernphysik (IKP), Karlsruher Institut für Technologie (KIT)

EUSO-TA is one of the fluorescence cosmic ray detector prototypes developed by the JEM-EUSO Collaboration. The prototype has two 1 m diameter Fresnel lenses and one photo detector module (PDM) as focal surface. The PDM consists of 36 multi-anode photomultiplier tubes from Hamamatsu. The prototype has been designed to get information about the calibration of the Fresnel lense system and the PDM, basic parts of the main space-based fluorescence detector under development.

EUSO-TA is located at the Black Rock Mesa site of the Telescope Array project (Utah-USA) and works in parallel with the TA fluorescence detectors since February 2015. During its campaigns, EUSO-TA detects cosmic ray events, as well as the pulsed laser from the Central Laser Facility, necessary for the detector calibration. Also planes and stars signatures are well visible in the data, although out of the scientific purpose.

The analysis of EUSO-TA data and the comparison of data with simulations will be shown.
