counter tube

Thân thiện

A scientist uses a counter tube to measure radiation in a laboratory.

Definition

1. Noun:
   • A measuring instrument for counting individual ionizing events: A counter tube is a device used in physics and radiation detection to count discrete events, such as the passage of ionizing particles or photons, by converting them into measurable electrical pulses.

Examples of Usage

• Noun:
  • The Geiger-Müller counter tube is a common type used for detecting radiation.
  • Scientists used a proportional counter tube to measure the low-energy particles.

Advanced Usage

• "to operate a counter tube": to use or run the instrument.
  • The technician learned how to operate the counter tube safely.

Variants and Related Words

• Geiger counter (n): A common radiation detection device that often uses a specific type of counter tube.
  • The Geiger counter clicked rapidly near the radioactive source.
• Proportional counter (n): A type of counter tube where the output pulse is proportional to the energy of the detected radiation.
  • The proportional counter provided detailed energy information about the particles.

Synonyms

• Radiation detector: A general term for devices that sense ionizing radiation.
• Particle counter: A device for counting subatomic particles.

Related Phrases

• Counter tube assembly: The complete unit containing the tube and its associated electronics.
  • The counter tube assembly was calibrated before the experiment.
