Write the Basic Principle of Operation of Gaseous Detectors for Nuclear Particle Detection.

ANSWER : Gaseous detectors work based on a simple principle to detect nuclear particles. They consist of a chamber filled with a gas, typically helium, argon, or a mixture of gases.

When a high-energy particle passes through the gas, it ionizes the atoms in the gas, creating positively charged ions and free electrons. These charged particles then move towards metal electrodes within the chamber, creating an electric current.

The current is amplified and measured to determine the presence and characteristics of the particle. By analyzing the current and its properties, scientists can identify the type, energy, and trajectory of the particles, providing valuable information in nuclear physics and particle detection.
