= Electron-ion recombination
<Electron-ion recombination> combines a free <electron> with a positive ion, reducing the number of <free charge> carriers. The released <binding energy> must be carried away, for example by a <photon> or another particle.
In an <ionization chamber>, recombination before charge collection reduces the measured signal. A simplified local model has loss rate $\alpha n_en_i$, with coefficient $\alpha$ depending on the species and conditions. Increasing the collection field can reduce the time available for recombination, but complete collection must be established experimentally rather than assumed from the applied voltage alone.
