PURPOSE:To simplify the electrode structure and to produce high brightness ion beam by employing a direct-heated filament in a cathode to accelerate in double stages while providing the ion accelerating function to the initial stage accelerating electrode thus eliminating the rear stage acceleration ...
Plasma electron gun for ribbon beam generation was designed on the basis of glow discharge with hollow cathode. Electrons were extracted through emission hole in the anode from plasma boundary, stabilized by metal mesh, and accelerated by the voltage applied between the anode and extractor. Electron...
but was estimated to be 0.5–1 mm mrad—a typical value measured directly at the gun, not expected to be affected by CSR during transport. The beam was focused to beta functions of ~10 × 10 mm2, with a waist close to the plasma entrance, with a relatively large chromaticity...
The plasma gun and the plasma plume, but also the kinpen are plasma sources emitting plasma “bullets”. Finally, plasma sources in which no direct line of sight to the plasma zone exists, are free from photons. These are some type of plasma jets and remote DBDs. In the following, a ...
Novel wound dressings with therapeutic effects are being continually designed to improve the wound healing process. In this study, the structural, chemical, physical, and biological properties of an electrospun poly glycerol sebacate/poly lactide acid/pl
Another form of plasma treatment, electron-beam technology is based on an electron gun shooting high-energetic electrons to a target object. By interaction and collision with matter in their pathway, the high-energetic electrons generate a multitude of exited molecules oxidizing VOCs and inorganic vol...
A flyback transformer is a transformer found in CRT monitors and televisions. It is used to create a high voltage and generate an electron beam to project pictures onto the screen. You can easily desolder a flyback out of a television or CRT monitor by using a blowtorch or for our purpos...
. In the surrounding air, the strongRaman scatteringof thelaser beamhas been subtracted. The electron density in the vicinity of the plasma jet nozzle has a maximum value of 5 × 10 18 −3 , and mean energies are up to 2.5 eV. The Rayleighmicrowave scattering(RMS) was first proposed ...
The crystallinity value was estimated by means of decomposing the Raman-spectra into three Gaussian shaped curves respectively corresponding to the three phases of silicon films. As an example, the decomposition of the 15-min samples is shown in inset of Fig. 4(b), where the blue, green ...
1. A method of generating plasma CVD using a plasma beam generating cathode and an anode located opposite the plasma generating cathode in a substantially vacuum chamber, a sheet plasma connecting the plasma generating cathode and the anode and dividing the vacuum chamber into a first subsection an...
