Measurement of Charged-Particle Stopping in Warm Dense Plasma
We measured the stopping of energetic protons in an isochorically heated solid-density Be plasma with an electron temperature of ~32 eV, corresponding to moderately coupled [(e[superscript 2]/a)/(k[subscript B]T[subscript e] + E[subscript F]) ~ 0.3] and moderately degenerate [k[subscript B]T[subscr...

| description | We measured the stopping of energetic protons in an isochorically heated solid-density Be plasma with an electron temperature of ~32 eV, corresponding to moderately coupled [(e[superscript 2]/a)/(k[subscript B]T[subscript e] + E[subscript F]) ~ 0.3] and moderately degenerate [k[subscript B]T[subscript e]/E[subscript F] ~ 2] “warm-dense matter” (WDM) conditions. We present the first high-accuracy measurements of charged-particle energy loss through dense plasma, which shows an increased loss relative to cold matter, consistent with a reduced mean ionization potential. The data agree with stopping models based on an ad hoc treatment of free and bound electrons, as well as the average-atom local-density approximation; this work is the first test of these theories in WDM plasma. |
