【 摘 要 】

EUSO-Balloon, a balloon-borne diffractive fluorescence telescope, was launched by the French Space Agency ONES from the Timmins base in Ontario (Canada) on August 25th in 2014. After reaching the floating altitude of about 38 km, EUSO-Balloon imaged the UV background for more than 5 hours before descending to ground using the key technologies of JEM-EUSO. A detailed and precise measurement of the UV background in different atmospheric and ground conditions was achieved. The instrument proved the capability of detecting Extensive Air Showers (EAS) by observing laser tracks with similar characteristics. This contribution will summarise the first results obtained concerning all the topics described above.
