GEM: Whistler-Mode Waves in the Radiation Belt: Propagation and Wave-Particle Interactions

该项目将开发一个2D混合等离子体模拟模型，以模拟哨声/合唱波在辐射带区域的传播及其与高能电子的相互作用。波的传播将在具有交叉场密度梯度的偶极磁场中建模，这将使研究波传导等现象成为可能。这项研究将研究哨声波和高能电子的非线性波-粒子相互作用以及产生大幅度波的过程。这些波在地球辐射带粒子的能量供应中起着关键作用。辐射带中粒子的能量在可能影响卫星的空间天气过程中发挥着重要作用。该项目还可能导致对辐射带补救方法的新理解。该项目将开发新的计算机代码，这些代码可能具有提供处理空间等离子体的变革性技术的潜力。大部分研究和代码开发将由研究生进行，因此该项目具有很强的教育效益。

This project will develop a 2D hybrid plasma simulation model to conduct simulations of the propagation of whistler/chorus waves in the radiation belt region and their interactions with energetic electrons. Wave propagation will be modeled in a dipole magnetic field with cross-field density gradients, which will make it possible to study phenomena such as wave ducting. The investigation will address nonlinear wave-particle interaction of whistler waves and energetic electrons and the processes that can generate waves with large amplitudes.These waves play a critical role in the energizaton of particles in Earth's radiation belts. The energization of particles in the radiation belts play an important role in space weather processes that can affect satellites. The project may also lead to new understanding of methods for radiation-belt remediation. The project will develop new computer codes that may have the potnetial to provide transformative techniques for dealing with space plasmas. Much of the reseach and code development will be carried out by a graduate student and the project therefore has strong educational benefits.
