TABLE I.

Correction factor, , for different beam qualities.

Generic image for table
TABLE II.

Measured dose rate and phantom scatter factors as a function of the field size. The normalization is done with respect to the reference field size of .

Generic image for table
TABLE III.

Output factors, , as a function of the field size. The second and third columns correspond to the experimental data and the results of the Monte Carlo simulations, respectively. A good agreement between both datasets is obtained.

Generic image for table
TABLE IV.

Dose rate measured at 2 cm depth in a solid water (sw) phantom [Easy cube (Ref. 48)] as a function of the field size. The ratio between the dose rate measured in the solid water and water phantoms [ratio (sw/w)] is shown in the third column.
