In October 2019, RADEC has participated in performance tests of the Lagrange, Radiation Monitor, Heavy Ion Telescope (HIT) at HIMAC facility located at National Institute of Radiological Sciences (NIRS, Chiba, Japan). Radiation Monitor as one of the in-situ instruments of the ESA Lagrange Mission is responsible for monitoring radiation storms (solar energetic particle events) as it is crucial, and can disrupt and damage spacecraft systems. Higher energy particles can als
