Abstract
The correction factor accounting for recombination losses of ionization in a chamber becomes quite significant when the instantaneous dose-rate present in the beam is very high, as happens in linear accelerators used for radiation therapy. This is particularly the case of pulsed-swept linacs, where the field homogeneity is obtained by scanning the whole area with a relatively small electron beam. This contribution describes some methods for taking into account recombination effects and presents some experimental results obtained on a pulsed-swept electron beam by using both an ionization chamber and other detectors which are dose-rate independent, such as Fricke solution and thermoluminescent dosemeters (TLD).
