Enhanced Raman scattering of a rippled laser beam in laser-plasma interaction
- Trang 115
Summary form only given, as follows. In the laser-plasma interaction
experiments, self-focusing and filamentation affect quite a large number of
other parametric processes including stimulated scattering processes. It has
also been experimentally observed that SRS is more prone to the nonlinearly
refraction-induced enhancement in the intensity of the filaments. This situation
is qualitatively well...

Sheet shaped plasma production using microwave-plasma interaction with ECR region
- Trang 320
Summary form only given. To control the shape of high density plasma has been
one of the issues for the application of plasma to industrial usages. Therefore,
ECR plasma is a good candidate of a high density plasma. A sheet shaped high
density plasma could be used to modify the surface of materials uniformly and as
the basis for electron accelerators. The discharge parameters, such as ECR
conditio...

Quantum extension of Child-Langmuir law
- Trang 172
Summary form only given, as follows. In the advent fields of nano-technology,
electrode gaps with scales down to nanometer regime can be fabricated. On such a
nano scale, quantum effects such as electron tunneling and the electron
exclusion principle become important in the study of beam-gap interaction. We
extend the classical Child-Langmuir law into the quantum regime including the
effects of el...

Surface coating by combining double-pulse plasma with plasma-based ion implantation
- Trang 259
Summary form only given. A newly developed coating system, named HPPC (Hybrid
Pulse Plasma Coating) System, incorporates PBH (Plasma-Based Ion Implantation)
with double-pulse plasma CVD which operates by synchronizing two pulses for gas
feed and plasma generation. The effect of the double-pulse plasma on the
uniformity of fragment-ion distributions in the plasma is described and is also
experiment...

Structures of microwave tunnel kiln
- Trang 295
Summary form only given. The electric field is uniform in the tunnel. The kiln
has a blanket with double layer thermal insulation. Varying the thermal
insulator can create the temperature gradient. The inner layer is made of mulite
base cement. The loss tangent of it is the order of 10/sup -2/ which is
equivalent to the work pieces. The microwave reflects on the metallic wall of
the tunnel repeate...

Dielectric Cherenkov maser with a magnetically confined plasma column in a dielectric rod slow-wave waveguide
- Trang 183
Summary form only given. Dielectric Cherenkov maser with a plasma column, an
axial dielectric rod and a thin annular relativistic electron beam (TAREB) is
studied in the presence of external magnetic field. The dispersion equations of
the beam-wave interaction are derived. The growth rates of the wave are
obtained, and the effects of the accelerating voltage, beam current and the
background plasma...

Modeling of discharges in atmospheric-pressure air sustained by travelling electromagnetic waves
- Trang 119
Summary form only given, as follows. Results are presented of simulation of
atmospheric-pressure air discharges sustained by electromagnetic surface waves
propagating along discharge tubes. The discharge model is developed with account
of nonequilibrium effects. Number densities of charged and neutral plasma
species are obtained by solving the system of kinetic equations, with rate
constants depen...

Investigation of ultrawideband pulses in wideband helix traveling wave tubes
- Trang 187
Summary form only given, as follows. The study of pulse propagation and
distortion in traveling wave tubes (TWTs) has many applications. First, it is an
attractive "diagnostic method" to characterize important properties such as
dispersion and nonlinear distortion over a broad frequency band. Second, it is
relevant to assessing the utility of TWTs as amplifiers for impulse radio,
impulse radar, or...

Influence of Ne-Xe gas mixture ratio on vacuum ultraviolet and infrared line in AC-PDPs
- Trang 103
Summary form only given, as follows. In order to improve the discharge luminous
efficiency for AC-PDP, the emission characteristics of VUV rays from xenon is
important for color AC-PDPs. The influence of Ne-Xe gas-mixture ratio on
resonance state Xe*(3p/sub 1/) and exited state Xe* (3p/sub 2/) has been
investigated. At first, we observed xenon 823 and 828 nm infrared light which
relates to VUV 173...

Study of the vacuum spark plasma soft X-ray sources
- Trang 255
Summary form only given, as follows. The vacuum spark plasma as a soft X-ray
source has been extensively studied due to its high efficiency of X-ray emission
when it is able to operate in the so-called micropinch regime. Applications of
soft X-rays in the fields of lithography, biology, medicine, etc. usually
require accurate dose controllability, besides proper spectrum and uniformity.
To meet th...
