mikrotötningsröntgenkammare
A mikrotötningsröntgenkammare, often translated as micro-discharge X-ray chamber, is a type of gas-filled detector used to sense X-rays. These chambers are designed to operate at very low pressures, significantly below atmospheric pressure. Their operation relies on the principle of gas amplification, where incident X-rays ionize the gas within the chamber. These initial ions then accelerate in an electric field, colliding with neutral gas molecules and creating secondary ion pairs. This cascade effect amplifies the initial ionization signal, making it detectable. The key characteristic of a mikrotötningsröntgenkammare is the use of a very small gap between electrodes or a specialized electrode geometry that facilitates micro-discharges. These micro-discharges are transient, localized electrical breakdown events within the gas. The detection of these discharges or the resulting current pulses allows for the measurement of X-ray intensity or energy. They are particularly sensitive and can be used for low-flux X-ray detection. Applications can include scientific research, medical imaging, and industrial inspection where high sensitivity and precise localization of X-ray sources are required. The precise design and gas mixture are critical for optimizing performance and achieving the desired sensitivity and energy resolution.
