Abstract
Thomson scattering of a laser beam was applied to study the plasma parameters inside a hollow anode having a ferroelectric plasma source incorporated in it. This method allowed avoiding difficulties related to spectroscopical measurements in the case of unknown electron energy distribution. It was found that the electron density and energy of the ferroelectric plasma are ∼1015cm−3 and ⩽5eV, respectively, and the density of the hollow anode bulk plasma is ∼6×1013cm−3. Applying an accelerating pulse for electron extraction from the bulk plasma leads to an increase in the electron density and energy of the ferroelectric plasma up to 6×1016cm−3 and ⩽20eV, respectively.
