Electron accelerators: History, applications, and perspectives
2014年2月1日 · Electron accelerators are multipurpose machines that deliver beams with energies spanning five orders of magnitude, and are used in applications that range from fundamental studies of particle interactions to cross-linking polymer chains in industrial plants.
How Particle Accelerators Work - Department of Energy
2014年6月18日 · A particle accelerator is a machine that accelerates elementary particles, such as electrons or protons, to very high energies. On a basic level, particle accelerators produce beams of charged particles that can be used for a variety of research purposes.
Accelerators - CERN
An accelerator propels charged particles, such as protons or electrons, at high speeds, close to the speed of light. They are then smashed either onto a target or against other particles circulating in the opposite direction.
Particle accelerator | Definition, Types, History, & Facts - Britannica
Electrons and protons, the particles most commonly used in accelerators, are found in all materials, but for an accelerator the appropriate particles must be separated out. Electrons are usually produced in exactly the same way as in a television picture tube, in …
World's smallest particle accelerator is 54 million times smaller …
2023年10月25日 · Scientists have created the world's first nanophotonic electron accelerator, which speeds negatively charged particles with mini laser pulses and is small enough to fit on a coin.

Accelerators are strings that can contain multiple modifiers and a single key code, combined by the + character, and are used to define keyboard shortcuts throughout your application. Accelerators are case insensitive.
Electron Accelerator - an overview | ScienceDirect Topics
All electron accelerators include a source (of electrons), an evacuated accelerating chamber, and a system for extraction from the vacuum and distribution over the product surface. Most accelerators obtain their electrons from a heated filament source called an electron gun.
Electron Accelerator - an overview | ScienceDirect Topics
An electron accelerator is a type of particle accelerator that uses beams of electrons to generate x-rays either inadvertently or deliberately for various applications in research, medicine, and industrial processes.
Accelerator technology development is based on new constructions and new components, what leads to progress in: Accelerator technology perfection (higher electrical efficiency, cost reduction); Reliability according to industrial standards; Accelerators for MW power beam level; Compact accelerator constructions;
Industrial accelerators can now provide electron energies greater than 10 MeV and average beam powers as high as 700 kW. The availability of high-energy, high-power electron beams is stimulating interest in the use of X-rays (bremsstrahlung) as an alternative to gamma rays from radioactive nuclides. 1 Introduction .
