The development of super-hydrophobic surfaces is important for basic research as well as various applications, such as stain resistant textiles, anti-biofouling paints for boats, and self-cleaning windshields for automobiles. In this paper, an all solid-state pulsed fluorine plasma generator, which can raise the hydrophobicity of cotton fabrics, is proposed. This generator consists of a DC power source,...
We identify three regimes of correlated GeV-electron/keV-betatron-x-ray generation by a laser-plasma accelerator driven by the Texas Petawatt laser, and relate them to variations in strength of blowout, injection geometry and beam loading.
We report self-injected quasi-monoenergetic (5% spread FWHM) acceleration of electrons to 2.0 ± 0.1 GeV by 0.6 PW-laser-driven wakefield acceleration in pure He plasma of density 5×1017 cm−3. Electron bunches diverge ∼0.5mrad, and contain ∼60 pC.
We report electrical properties and Optical Emission Spectrum of DC-Driven Microplasma Reactor for Scanning Plasma Etching in pure SF6 environment with different device size between 5–12 kPa gas pressures. The Microplasma Reactor is consists of metal-insulator-metal sandwich structure, and with an inverted pyramidal shape hollow cathode. A diagnostic system is design to measure the V–I curve and OES...
We demonstrated single-shot frequency-domain tomographic imaging of laser-produced refractive index structures that evolve during propagation, using multiple probe pulses multiplexed to a single spectrometer and tomographic reconstruction algorithms.
Summary form only given. In order to gain an insight into the process of co-monomer pulse r.f. inductively coupled plasma, the plasma gas phase was investigated by the optical emission spectroscopy and mass spectroscopy for the different reactive compositions. Styrene monomer, accompanied by anther monomers (MMA, HEMA, tetraglyme, and diglyme) with similar chemical structure was applied to plasma...
We report the extension of Frequency-Domain Holography to a Frequency-Domain Streak Camera capable of capturing the evolution of refractive index structures propagating at luminal speeds. Possibility of extension to Frequency-Domain Tomography is demonstrated.
Recently, all solid-state pulsed power modulators, which are operated with high repetition rate, long lifetime and high reliability, have been developed to be used for industrial applications of plasmas, such as high repetition rate pulsed gas lasers, high energy density plasma (EUV sources) and pulse ozonizer. We have studied and developed high repetition rate compact pulsed power modulator for discharge...
