SU‐E‐T‐625: Use and Choice of Ionization Chambers for the Commissioning of Flattened and Flattening‐Filter‐Free Photon Beams: Determination of Recombination Correction Factor (ks)

Purpose: To evaluate the recombination effect for some ionization chambers to be used for linacs commissioning for Flattened Filter (FF) and Flattening Filter Free (FFF) photon beams. Methods: A Varian TrueBeam linac with five photon beams was used: 6, 10 and 15 MV FF and 6 and 10 MV FFF. Measuremen...
