  This work investigates the electronic stopping power for protons of a
tungsten plasma at various electron densities and temperatures. The study
employs a dielectric formalism to model the stopping power due to free and
bound electrons, considering relativistic and non-relativistic effects. The
bound electron stopping power is modeled using the shellwise local plasma
approximation (SLPA) introduced by Montanari and Miraglia. The ionization state
of the plasma is also examined, revealing its impact on the bound electron
contribution. We compare our results with the T-Matrix approach and the
Li-Petrasso model for free electrons in combination with SLPA calculations for
the bound electron ones. Results demonstrate the significance of bound electron
stopping power, particularly for plasma with high-Z ions. This investigation
contributes valuable insights into plasma physics and fusion energy research,
providing essential data for future experiments and simulations.
