Feasibility of using a dose-area product ratio as beam quality specifier for photon beams with small field sizes

•DAPR20,10 properties are investigated in photon beams with field sizes below 2 cm.•Influence of field size on photon spectrum and dosimetric parameters is evaluated.•Measurements by ionization chambers with different characteristics are compared.•Results on DAPR20,10 obtained with two different acc...
