Production of high densities of energy using a microparticle beam
نویسنده
چکیده
The electrostatic acceleration of charged iron macroparticles is considered. These macroparticles are directed toward the center of a sphere and energy densities above 2 megajoules/cm3 are expected. The conversion of the kinetic energy of the beam into heat results in very high temperatures, possibly in the fusion range. Revue Phys.

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...
متن کاملVibration Analysis of Material Size-Dependent CNTs Using Energy Equivalent Model
This study presents a modified continuum model to investigate the vibration behavior of single and multi-carbon nanotubes (CNTs). Two parameters are exploited to consider size dependence; one derived from the energy equivalent model and the other from the modified couple stress theory. The energy equivalent model, derived from the basis of molecular mechanics, is exploited to describe size-depe...
متن کاملProduction of [18F] fluoride with a high-current two layer spherical gold target
Background: Fluoride-18 is the most widely used radioisotope for Positron Emission Tomography (PET). [18F] 2-flouro- 2-deoxy D-glucose (FDG) has become a standard tool in the area of clinical research. The oxygen-18 enriched water is the most widely used target for the production of fluoride-18. The use of the nuclear reaction 18O (p,n)18F has been found as the most effective method for the pro...
