| الوصف: | The structure of a strong collisional shock front forming in a plasma is directly probed for the first time in laser-driven gas-jet experiments. Thomson scattering of a 526.5 nm probe beam was used to diagnose temperature and ion velocity distribution in a strong shock ($M\ensuremath{\sim}11$) propagating through a low-density ($\ensuremath{\rho}\ensuremath{\sim}0.01\text{ }\text{ }\mathrm{mg}/\mathrm{cc}$) plasma composed of hydrogen. A forward-streaming population of ions traveling in excess of the shock velocity was observed to heat and slow down on an unmoving, unshocked population of cold protons, until ultimately the populations merge and begin to thermalize. Instabilities are observed during the merging, indicating a uniquely plasma-phase process in shock front formation. |
