Show Abstract
Plasma density is one of the most important parameters for laser wakefield acceleration using a gas-filled capillary waveguide. We measured the evolving hydrogen plasma densities in capillary discharge by using two different diagnostics methods at the same time, i.e., the Stark-effect-based spectroscopy and the transverse interferometry methods. It was found that there is a rather large difference between two methods and the phenomenon is explained in view of self-absorption. The correlation was obtained and the result is quite useful for capillary-plasma-based laser wakefield acceleration research.

Show Abstract
We present a simple non-intrusive experimental method allowing a complete single shot temporal measurement of laser produced plasma filament conductivity. The method is based on filament interaction with low intensity microwave radiation in a rectangular waveguide. The suggested diagnostics allow a complete single shot temporal analysis of filament plasma decay with resolution better than 0.3 ns and high spatial resolution along the filament. The experimental results are compared to numerical simulations, and an initial electron density of 7 × 1016 cm−3 and decay time of 3 ns are obtained.

Show Abstract
Microcavity plasma arrays of inverse pyramidal cavities fabricated on p-Si wafers act as localized dielectric barrier discharges. When operated at atmospheric pressure in argon and excited with high voltage at 10 kHz, a strong interaction between individual cavities is observed leading to wave-like optical emission propagating along the surface of the array. This phenomenon is numerically investigated. The computed ionization wave propagates with a speed of 5 km/s, which agrees well with experiments. The wave propagation is due to the sequential drift of electrons followed by drift of ions between cavities seeded by photoemission of electrons by the plasma in adjacent cavities.
