RADiation-hard Electron Monitor (RADEM)
JUpiter ICy moons Explorer (JUICE) is a part of ESA’s Cosmic Vision programme. It’s a large-class spacecraft dedicated for observations of Jupiter and it’s three largest moons: Ganymede, Callisto and Europa. JUICE will explore the conditions of the planet formation, life emergence and mechanisms of the Solar System. Launch of JUICE is planned for 2022. With 7 years of transfer, it will spend 3 years studying Jovian system.
RADiation-hard Electron Monitor (RADEM) is an instrument onboard JUICE spacecraft conducting measurements of the Jupiter radiation environments. It will provide information on electrons, protons and heavy-ion fluxes, spectra, and incoming directions.

JUICE mission camera
JUpiter ICy moons Explorer (JUICE) is a part of ESA’s Cosmic Vision programme. It’s a large-class spacecraft dedicated for observations of Jupiter and it’s three largest moons: Ganymede, Callisto and Europa.The JUpiter ICy moons Explorer (JUICE) is an ESA interplanetary spacecraft being developed to perform detailed investigations of the Jupiter system and three of its icy moons: Europa, Callisto and Ganymede. The emphasis will be given on Ganymede as a small planetary body to be studied as a potential habitat. The spacecraft is set for launch in 2022 and would reach Jupiter in 2030. Two identical optical cameras are proposed for the mission to monitor the spacecraft and its surroundings. The sensors of the cameras need to be protected from hazardous radiation levels caused by extremely high fluxes of very energetic electrons. .
SE2S team responsibilities
- Radiation environment modelling
- Full mass model and radiation damage modelling
- Radiation analysis and shielding optimization
- MC simulation for DD and TID and SEE of preselected components
- Damage estimations and predictions
Radiation detectors for Lagrange mission
Lagrange is a planned solar weather mission by the European Space Agency (ESA). It envisions two spacecraft to be positioned at Lagrangian points L1 and L5. Monitoring space weather includes events such as solar flares, coronal mass ejections, geomagnetic storms, solar proton events, etc. The spacecraft are anticipated to launch in the mid 2020s.
SE2S team responsibility to date:
- Concept and its validation,
- design of detectors and preliminary electronics,
- testing and qualification,
- verification,
- radiation analysis,
- radiation qualification of electronic components and detector elements
- mechanical analysis
- thermal analysis and thermal model qualification.
