TL;DR
Mini-EUSO is a space-based UV detector on the ISS designed to observe cosmic-ray air showers, and a steerable UV laser system is tested to calibrate and evaluate its performance.
Contribution
This paper reports on the testing of a mobile UV laser system to calibrate and validate Mini-EUSO's cosmic-ray detection capabilities from space.
Findings
Laser system stability within 5%
Laser pulses simulate EAS brightness for energies up to 10^21 eV
Implementation of laser characteristics in simulation framework
Abstract
Mini-EUSO (Extreme Universe Space Observatory) is a small-scale prototype cosmic-ray detector that will measure Earth`s UV emission and other atmospheric phenomena from space. It will be placed in the International Space Station (ISS) behind a UV-transparent window looking to the nadir. The launch is planned this year (2019). Consisting of a multi-anode photomultiplier (MAPMT) camera and a cm diameter Fresnel lens system, Mini-EUSO has a \ang{44} field of view (FoV), a km spatial resolution on the ground and a s temporal resolution. In principle, Mini-EUSO will be sensitive to extensive air shower (EAS) from cosmic-rays with energies above eV. A mobile, steerable UV laser system will be used to test the expected energy threshold and performance of Mini-EUSO. The laser system will be driven to remote locations in the Western US and aimed across the…
