Definition
- Noun:
- A stream of charged particles (ions) traveling together with uniform direction and velocity: An "ionic beam" is a focused, collimated flow of ions that move in a coordinated manner, all heading the same way at the same speed. It is a fundamental concept in physics and engineering.
Usage Examples
- Noun:
- The laboratory uses a powerful ionic beam to etch microscopic patterns onto silicon wafers.
- Scientists analyzed the material's composition by directing an ionic beam at its surface.
- The stability and focus of the ionic beam are critical for the experiment's success.
Advanced Usage
- "to generate an ionic beam": to create and accelerate a stream of ions.
- The new accelerator can generate a highly stable ionic beam.
- "ionic beam irradiation": the process of exposing a material to a beam of ions.
- The sample underwent ionic beam irradiation to study its radiation resistance.
Variants and Related Words
- Ion beam (n): A common synonym for "ionic beam."
- Ion beam lithography is a precise manufacturing technique.
- Particle beam (n): A broader term for a stream of particles, which can include ions, electrons, or protons.
- The facility is equipped to produce various types of particle beams.
Synonyms
