How ionization chamber is different from scintillation counter? 


Best insight from top research papers

An ionization chamber operates by measuring the ion pairs produced when radiation interacts with the gas inside the chamber, detecting the resulting current. In contrast, a scintillation counter like the liquid xenon proportional scintillation counter (LXePSC) detects radiation by converting it into light pulses through electroluminescence in the liquid xenon medium. Ionization chambers are suitable for measuring low currents, while scintillation counters are efficient in detecting low-energy electronic recoils, such as those from beta decays, down to approximately 1 keV. Additionally, ionization chambers can be optimized for high counting rates, as seen in the fast ionization chamber designed for fusion studies at high particle counting rates. In summary, ionization chambers focus on measuring ionization current, while scintillation counters excel in detecting radiation through light emission in specific mediums.
