TL;DR
Mini-EUSO is a space-based UV telescope on the ISS that measures Earth's UV emissions, and this paper details its calibration, field operations, and data analysis to ensure accurate measurements.
Contribution
This paper presents the end-to-end calibration process of Mini-EUSO, including the UV flasher, field campaign operation, and data analysis methodology.
Findings
Calibration results match expectations within uncertainties
Effective atmospheric attenuation correction applied
Operational data demonstrates system stability
Abstract
Mini-EUSO is a wide Field-of-View (FoV, 44) telescope currently in operation from a nadia-facing UV-transparent window in the Russian Zvezda module on the International Space Station (ISS). It is the first detector of the JEM-EUSO program deployed on the ISS, launched in August 2019. The main goal of Mini-EUSO is to measure the UV emissions from the ground and atmosphere, using an orbital platform. Mini-EUSO is mainly sensitive in the 290-430 nm bandwidth. Light is focused by a system of two Fresnel lenses of 25 cm diameter each on the Photo- Detector-Module (PDM), which consists of an array of 36 Multi-Anode Photomultiplier Tubes (MAPMTs), for a total of 2304 pixels working in photon counting mode, in three different time resolutions of 2.5 s, 320 s, 40.96 ms operation in parallel. In the longest time scale, the data is continuously acquired to monitor the UV…
