Summary of Dose Rate independence study for the IAS3 read-out electronics (associated to the PV-aS1000 detector). Example of Gamma Evaluation matrices (DTA = 3 mm, ΔD = 3%) for a field measured with beam delivery operated at dose rates from 100 to 600 MU/min while dose calculation was performed at 300 MU/min. Plots of the calibration data acquired at different dose rates and corresponding fits.
