Description

Jiawei showed me a recent Science Advance paper of combining Chang-E lunar proton flux observation with test particle simulation of protons in the MeV range (A galactic cosmic ray cavity in Earth-Moon space). We may think of reproducing their results.

Contributor guide

Research direction
Read the paper 'A galactic cosmic ray cavity in Earth Moon space' to understand the simulation setup, then implement a similar test particle simulation using TestParticle.jl to reproduce the GCR cavity results.
