Measurement of supra-thermal plasmas in the planetary magnetosphere

Details of research theme

Supra-thermal particles are abundant in the planetary magnetospheres and ionospheres. Excitation, damping, and propagation of plasma waves are significantly affected by the supra-thermal particles, and then, they further affect acceleration, scattering, and loss of high-energy plasma particles through resonant interaction between the particles and the waves. However, there are only few observations of the supra-thermal particles. Measurement of the supra-thermal particles in future planetary magnetospheric missions should be crucial. Contributions to the ERG project and the future FACTORS mission are expected in this research. The following list suggests research topics.

Contribution to the project:
• Participate in the satellite operation and planning in collaborating with the satellite operation team
• Participate in the calibration and the data processing of the instrument teams and contribute to improving the quality of science data
• Understand the satellite system working in space, and then, participate a designing of the future satellite mission FACTORS as one of the leading researchers, including a strategy to observe supra-thermal particles.

Research synergetic with the contribution to the project:
• Improve research skills in the space environment, space weather, and space plasma including behavior of plasma particles in the planetary magnetosphere.
• Design and manufacture the supra-thermal plasma analyzer, and then, calibrate it through laboratory experiments.

Required abilities，qualities， and experience

Project researchers are required to contribute scientific data evaluation processes and development of particle instruments through laboratory experiments. Experiences of instrument development for space observation are highly welcomed.
