Uncontrolled Exuberance

• We now have the tools to analyze thermal to radiation belt plasmas (0<E<MeV) with radial diffusion models:

  • Diffusion coefficient: D(U,B,K,m)=D(x,y,K,m)
  • Convection coefficient: v(U,B,K,m)
  • Coulomb drag coefficient: C(U,B,K,m)
  • Charge exchange rate: X(U,B,K,m)

• df/dt = d/dq(Dqq df/dq) + vq df/dq + C df/dm + Xf
