Material Irradiation Damage Studies for High Power Accelerators
نویسندگان
چکیده
The feasibility of multi-MW accelerators, currently under consideration and study, is directly linked to the production target and its survivability under severe shock and high irradiation exposure. The limitations of solid materials to function as high performance targets and in particular the effects of irradiation on key material properties are assessed through an extensive experimental study and findings to-date are presented and discussed.

Irradiation damage studies of high power accelerator materials
High-performance production targets and other critical accelerator components intercepting intense, energetic proton beams are essential as the accelerator community envisions the next generation, multi-MW accelerators. Materials that have served the nuclear sector well may not be suitable to play such a role which demands that the material comprising the beam-intercepting element must, in addi...

Electron beam accelerators technology has made significant progress in environmental applications in recent years. Including some environmental applications of industrial accelerators, is clearing the air from oxides of nitrogen and sulfur(NOx , SOx) produced by industrial facilities. Combustion of coal, oil, natural gas and other gases that are produced in power plant, refineries and industri...
متن کاملIrradiation Damage Studies in Solid Targets*
In an effort to address the limitations on high-power accelerator target performance prompted by the elevated dose levels and the associated irradiation damage, an experimental study has been conducted to explore interesting new alloys and composites under the influence of protons and neutrons. Material irradiations were performed using the 200-MeV protons of the BNL Linac operating with an eff...

Background: Exposure to ionizing radiation is known to induce oxidative stress followed by damage to critical biomolecules like lipids, proteins and DNA through radiolysis of cellular water. Since radiation has been widely used as an important tool in therapy of cancer, the detailed investigation regarding the DNA damage and repair kinetics would help to predict the radiation sensitivity of cel...
متن کاملCurrent Status of Reduced-Activation Ferritic/Martensitic Steels R&D for Fusion Energy
Reduced-activation ferritic/martensitic (RAF/M) steels have been considered to be the prime candidate for the fusion blanket structural material. The irradiation data obtained up to now indicates rather high feasibility of the steels for application to fusion reactors because of their high resistance to degradation of material performance caused by both the irradiation-induced displacement dama...
