Abstract
Background: On JUICE, the L-class mission of ESA to the Jupiter system the particle environmental package (PEP)will be used to explore Jovian plasma system using remote global imaging and in situ measurements. In particular,
the mass spectrometric measurements of Jovian moons exospheres will be carried out using a neutral/ion mass spectrometer (NIM). Because the exospheres of the icy Jovian moons’ consist of the material originating directly from the surfaces, the measurements deliver at the same time the chemical composition of the moons’ surface and an insight into the evolution of these objects with time, since they started from the same chemical inventory. Methodology & Theoretical Orientation: The instrument to test against the physical and environmental conditions expected in the Jupiter environment, and measurements near these moons is currently tested. Also, unique laboratory experiments simulating the icy surfaces of the Jovian moons and their response to particle radiation in forming their exospheres are under way accompanying by theoretical modelling of the chemical composition of exospheres. In addition, we will be discussed studies which are conducted to develop necessary shielding against the high energy radiation around Jupiter to protect the instruments.
