Low Velocity Proton Stopping Power Measurements in Warm Dense Carbon

Understanding the physics of ion stopping in warm dense matter (WDM) is of great interest both for fundamental science and inertial confinement fusion. The theoretical description of the ion stopping power in WDM is challenging notably due to electron coupling and degeneracy, and the experimental database is essentially missing. In particular, the low velocity stopping power regime where v p (ion velocity) ~ v th (electron thermal velocity), near the Bragg peak, where the largest modeling uncertainties are reported, remains virtually unexplored.
