ion beam

A scientist adjusts the ion beam in the laboratory.

Definition

Noun: A stream of ions (electrically charged atoms or molecules) that are all moving in the same direction and at the same speed. It is a focused, directional flow of charged particles.

Usage

An "ion beam" is a scientific and technical term used primarily in physics, engineering, and materials science. It describes a controlled, collimated stream of ions used for purposes such as analysis, modification, or propulsion.

Examples
  • The researcher used an ion beam to etch a microscopic pattern onto the silicon wafer.
  • In space propulsion, an ion beam provides thrust by accelerating charged particles out of the engine.
  • The mass spectrometer separates molecules by directing an ion beam through a magnetic field.
Advanced Usage
  • Ion beam analysis: A technique for determining the composition and structure of materials by studying how a sample interacts with an ion beam.
  • Ion beam implantation: A process used in semiconductor manufacturing to introduce dopant atoms into a substrate by bombarding it with a high-energy ion beam.
  • Focused ion beam (FIB): A specific instrument that uses a finely focused ion beam for imaging, milling, or depositing material at the nanoscale.
Variants and Related Words
  • Ion (noun): An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  • Beam (noun): A line of light or other radiation, or a stream of particles.
  • Particle beam (noun): A more general term for a stream of charged or neutral particles, which includes ion beams and electron beams.
  • Plasma (noun): An ionized gas containing positive ions and free electrons, which can be the source for generating an ion beam.
Synonyms
  • Ion stream
  • Particle beam (when the particles are specifically ions)
Related Phrases
  • Ion beam etching/material removal: The use of an ion beam to physically sputter away atoms from a surface.
  • Ion beam deposition: The use of an ion beam to add material onto a surface.
  • Ion beam therapy: A type of radiation therapy for cancer that uses a beam of protons or other ions.
