Plasma Universe Science Objectives Validation with Binary Systems Dynamics

Explore fast-rotating plasma disk dynamics and interaction between torus and disk in a plasma universe. Investigate binary systems’ electrodynamic interactions and their effects on matter transport. Address questions on radiation effects and dusty plasmas in cosmic environments. Plan required measurements with detailed instrument specifications and spacecraft configurations for optimal data collection.

Presentation Transcript

  1. a. Validation of the proposed major science objectives Topic 1: Fast rotator • Electrodynamics of plasma disk [Plasma Universe]- Stationary state: global structure (B-field, different species, sources/sinks)- Dynamics: Relaxation of rotational energy Processes? Typical spatial and temporal scales (driven, internal?) Consequences (aurora, radio, Xray) • A complex multi phase system [origin, plasma universe]- interaction between ‘neutral’ torus and the plasma disk Topic 1 is coupled to Topic 2  transport of matter

  2. a. Validation of the proposed major science objectives Topic 2: Binary systems • Electrodynamics of interaction [Plasma Universe]- 3 different cases: Io / Europa / Ganymede- MHD / kinetic interaction. Alfvén waves and acceleration (associated aurora, radio emissions and electron beams, Xrays(?))- Pick up ions – source terms • Plasma/surface, plasma/exosphere interactions [Satellite, Plasma Universe]- sputtering- surface weathering, implantation of heavy ions (connection to Bepi-Colombo)- Pick up ions – source terms- Charge exchange processes

  3. a. Validation of the proposed major science objectives Other questions: • Radiation and lifeWhy a so large level of radiation?Combined: magnetic field + rotation + scales • Dusty plasmasPlasma disk / Dust population

  4. b. Identification of the required measurements Measurement requirements: • Magnetic field: 3D @ 100 Hz., 10 kHz 2x • Electric field: 2D @ 40 MHz 1x RS • Plasma: from eV to 10 MeVfew seconds resolution- e- low energy: 3D 2x- ions low energy: (composition?) 3D, up to sulphur… 2x- e- high energy: 1x RS- ions high energy: 1x + radiation monitor EO- neutrals: low energy on EO and high energy on RS- dust 1x EO • A spinning spacecraft is better! • Ground based complementary observations similar to IJW.

  5. Europa Orbiter: Magnetic field (2 kg), Plasma LE (4 kg), Neutrals LE (1.5 kg), Dust (2 kg) Radiation monitor (0.5 kg) 10 kg 8 W in addition Very low energy plasma (Langmuir probe) (0.3 kg) For better understanding magnetospheric interaction add electric field (4 kg) Relay S/C: Magnetic field (2 kg) Electric field (4 kg), Plasma LE+HE (6 kg), Neutrals HE (3 kg)  15 kg 14 W in addition Imager? Xray detector? c. Instruments mass and power(minimal mass, no shielding)
