Detectors

Definition

Detectors are devices or systems used to sense and measure specific physical quantities, such as radiation, particles, or energy levels. They play a crucial role in data acquisition and analysis systems by converting the detected signals into measurable data that can be processed and analyzed further. Detectors help in monitoring and understanding various phenomena, providing essential information for research, safety, and operational efficiency.
