Session: Space Weather Instrumentation
The LGR Radiation Monitor (LGR-RM) for the ESA Lagrange mission is a part of the satellite in-situ instrument suite. RM is devoted to detecting electrons, protons, and heavy ions in an extended energy range and high flux conditions. The electron and proton detection systems use previously developed technologies. The heavy-ion detector (HIT) represents a novel design utilizing scintillators and SiPM light converters. HIT electronics is equipped with a dedicated ASIC and optimized for fast signal detections. A representative model of HIT was developed at PSI to verify RM requirements for energy measurement and ion identification. An intensive test campaign was performed at HIMAC NIRC. One used several heavy ion species ranging from He to Fe with energies from 5 to 500 MeV/n. A separate set of tests carried out in GANIL and PSI aimed to characterize the ASIC and SiPM radiation hardness including SEE and DD effects. We report on test measurements as well as present radiation hardness qualification of ASIC and SiPMs. Results are discussed and compared with both mission requirements and Monte Carlo simulations, Implications on the final design of the instrument are provided.
