PURPOSE:To obtain an effective projecting area free from deflection with high resolving power by a method wherein a dynamic converging lens system for setting an electron beam source image and a dynamic deflection system for deflecting electron beam flux are provided at the front focal point ...
No ionizing radiation after machine is turned off. • No liquid effluents. • Nothing is added to the waste, room temperature process. • Low operating cost. • Automated technology. On the other hand, electron beam technology has the following precautions: • Personnel should be protecte...
Theelectron beamcan be considered as an electron pole that results in anelectrostatic fieldand leads to the bending. The component of the electric field perpendicular to the axis of the nanowire (E⊥), which forces the nanowire bending, is deduced and is found proportional to the current densit...
In Electron Beam Technology (EBT), the raw material used is either metal powder or wire. Metal powders can be fused to a solid mass by an electron beam, which acts as a heat source. Components are mass-produced in a high vacuum atmosphere with an electron beam by melting the powder. Th...
As an important metal three-dimensional printing technology, electron beam melting (EBM) is gaining increasing attention due to its huge potential applications in aerospace and biomedical fields. EBM processing of Ti-6Al-4V as well as its microstructure and mechanical properties were extensively investig...
(VSM). The dielectric measurements were carried out in the frequency range 10–1to 107Hz at room temperature by employing Alpha-A machine from novocontrol. Samples were irradiated with 3 MeV electron beam at different dose (10, 20, and 30 kGy) at room temperature by Vivi rad (France) ...
However, raw protein samples are extremely vulnerable to irradiation damage by electron beams; where even for observations at liquid-nitrogen temperature, the samples are reportedly damaged at a beam irradiation of approximately 20 electrons/Å2. This implies that raw protein samples must be observed...
we demonstrate hyperfine-structure-resolved laser spectroscopy of HCIs in an electron beam ion trap plasma, employing the magnetic-dipole transition in the 4d95sstate of127I7+. Ion-state manipulation by controlled electron collisions in the well-defined laboratory plasma enables laser-induced fluorescence...
FIG. 3A is a diagram showing a schematic configuration of a second unit of the electron beam device. FIG. 3B is a diagram schematically showing a positional relation between a cylindrical member and an inner edge of a lens; FIG. 4 is a diagram showing that the first unit and the second...
Electrical power is transmitted from a transmitting location to a remote receiving location by means of an electron beam injected into an evacuated magnetically shielded pipe extending between the tra
