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...

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...

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...

Multi-jet atmospheric glow plasma for PCB desmear process
- Trang 146
Summary form only given. The plasma desmear process is widely used in the
printed circuit board industry. During drilling, drill bits become heated
resulting in the melting and smearing of the epoxy-resin base material across
the inner-layer copper surfaces within the hole barrel to which subsequent
through-hole plating must connect. If not corrected, the smear would constitute
a dielectric layer ...

Study of atmospheric pressure glow discharge
- Trang 147
Summary form only given. Atmospheric pressure glow discharges (APGD) in gases
such as Helium, Argon and air were studied. APGD in Helium between two parallel
plane electrodes covered with dielectric plates was simulated on the basis of
one-dimensional fluid model and the parameters' distributions along the
discharge channel were obtained. The development of an electron avalanche in one
atmosphere ...

Monte Carlo simulation of radiation trapping in electrodeless lamps: a study of collisional broadeners and isotopic abundances
- Trang 319
Summary form only given, as follows. Electrodeless gas discharges are finding
increasing applications as lighting sources, especially for Ar/Hg based
fluorescent lamps. The particulars of resonance radiation trapping from Hg are
an important consideration in the design of these sources. For simple
geometries, analytical forms of the radiation trapping factor can be obtained.
For current lamp desig...

Cell geometry designs for efficient plasma display panels
- Trang 101
Summary form only given, as follows. We use a two-dimensional self-consistent
simulation model to study the effect of the geometric parameters on the
operating voltages and the efficiency of a coplanar-electrode plasma display
panel cell. For the standard coplanar-electrode geometry it is found that there
is a trade-off between high efficiency and low operating voltages as the
electrode gap, or ot...

Carbon nanotube cathode research at AFRL
- Trang 151
Summary form only given, as follows. Single-wall and multi-wall nanotubes have
shown some promise as field emission cathodes. Most applications have focused on
small surface areas with such uses as flat panel displays. The Air Force
Research Laboratory has begun to investigate the uses of these cathodes for
larger areas. Several types of nanotube cathodes have been investigated. Each
type is imple...

Warm dense matter and idealized slab plasma
- Trang 163
Summary form only given. Warm Dense Matter is a term that I introduced several
years ago to draw attention to a class of states that is of interest to a broad
range of disciplines. These include plasma physics, condensed matter physics,
high pressure science, inertial confinement fusion, planetary science,
astrophysics, as well as material science under extreme conditions. Warm Dense
Matter refers...

Space charge saturation of Faraday cup detectors used in laser-produced plasmas studies
- Trang 110
Summary form only given, as follows. Faraday cups are commonly used to measure
plasma expansion characteristics in laser-produced plasmas. In its simplest
design a Faraday cup consists of a grounded entrance grid and a biased collector
plate. As an expanding laser plasma flows into the Faraday cup, the entrance
grid, with a mesh size smaller than the local Debye screening length, separates
electro...
