The extrapolated values of ks operated at 300 V and ks factors obtained using the two‐voltage technique at the voltage ratio of 3 for the Physikalisch‐Technische Werkstaetten (PTW) Advanced Markus (a) and the Ion Beam Application (IBA) PPC05 (b) chambers as a function of dose rates. Note that some of ks values from the linear and the semiempirical models are below unity after corrected for a possible charge multiplication effect
