Plasma accelerator was used for the deposition of a material powder placed at a breach. A capacitor bank of 46.26 μF charged to 3 kV (208.17 J) gave a peak current of 8.8 kA after 15 μs. Plasma inductance varied between 3 μH and 1.5 μH while the plasma resistance varied between 5 m­ and 300 m­ within one shot, while the electron temperature and plasma density near the substrate measured with a double electric probe was about 3 eV and 2.7 × 1013 cm−3, respectively. Carbon plasma velocity at the muzzle was 6.0 cm/μs which agrees with calculations. The deposited graphite powder showed mostly a homogeneous distribution of clusters. The total efficiency of the system, considering both the internal and kinetic energy, was found to be 10.9%.
