betatron
/'bi:tətrɔn/
Definition
Noun: 1. A type of particle accelerator: A betatron is a circular device that accelerates a continuous beam of electrons to very high speeds. It operates using the principle of electromagnetic induction, where a changing magnetic field creates an electric field that propels the electrons.
Usage
The term "betatron" is a technical, scientific noun used specifically in the fields of physics and engineering. It refers to a historical and specific design of an electron accelerator. * The betatron was an important early machine for studying high-energy electrons. * In the 1940s, the betatron was used to produce high-energy X-rays for medical and industrial purposes.
Advanced Usage
- Historical Context: The betatron, invented by Donald Kerst in 1940, was a pioneering device in particle physics before the development of more powerful synchrotrons and linear accelerators. Its operation is often contrasted with other accelerators like the cyclotron.
Variants and Related Words
- Particle Accelerator (n): The general category of devices that use electromagnetic fields to propel charged particles to high speeds. A betatron is one type of particle accelerator.
- Induction Accelerator (n): Another name for a betatron, highlighting its operating principle of electromagnetic induction.
- Synchrotron (n): A more advanced type of circular particle accelerator that succeeded the betatron.
Synonyms
- Induction accelerator
Related Terms (Not Synonyms)
- Cyclotron: A different type of circular particle accelerator that uses a constant magnetic field and an alternating electric field.
- Linear Accelerator (Linac): A particle accelerator in which particles are accelerated in a straight line.
- Electron Beam: A stream of high-energy electrons, such as the one produced by a betatron.
Noun
-
accelerates a continuous beam of electrons to high speeds by means of the electric field produced by changing magnetic flux
