What is ionisation chamber?

Noun an instrument for detecting ionizing radiation. For data analysis, diffraction patterns were corrected for uneven detector response and normalized to the ionization chamber, i.e., the ionization chamber, also known as an ion chamber, is an electrical device that detects various types of ionizing radiation. The detector voltage is adjusted so that the conditions correspond to the ionization region, and the voltage is insufficient to cause gas amplification (secondary ionization). The detectors in the ionization region operate at a low electric field strength, so gas multiplication does not occur.

The collected load (output signal) is independent of the applied voltage. Individual minimum ionization particles tend to be quite small and generally require special low-noise amplifiers for efficient operating performance. Ionization chambers are preferred for high radiation dose rates because they have no “downtime”, a phenomenon that affects the accuracy of the Geiger-Mueller tube at high dose rates. This is because there is no inherent signal amplification in the operating medium; therefore, these meters do not require much time to recover from large currents.

In addition, because there is no amplification, they provide excellent energy resolution, which is mainly limited by electronic noise.
