Electron-gun simulations explain the mechanisms of high-energy cosmic rays

A new study provides a rudimentary model for simulating cosmic rays' collisions with planets by looking at the model of electrons detached from a negative ion using photons. Physicists have for the first time demonstrated that they can control the dynamics of negative ion detachment via photons, or photodetachment, on a moving surface.
