Abstract:
'K-EUSO is a planned mission of the JEM-EUSO program for the study of ultra-high energy cosmic rays (UHECR) from space, to be deployed on the International  space Station.  The K-EUSO observatory consists of a UV telescope with a wide field of view, which aims at the detection of fluorescence light emitted by extensive air showers (EAS) in the atmosphere.  The EAS events will be sampled with a time resolution of 1--2.5~$mu$s to reconstruct the entire shower profile with high precision.  The detector consisting of $sim 10^{5}$ independent pixels will allow a spatial resolution of $sim$700~m on ground. From a 400~km altitude, K-EUSO will achieve a large  and full sky exposure to sample the highest energy range of the UHECR spectrum. In this contribution, we present estimates of the  performance of the observatory: an estimation of the expected exposure and triggered event rate as a function of energy and the event reconstruction performance, including resolution of arrival directions and energy of UHECRs.'
