Comparison of the measured and calculated beam characteristics for new 7 MeV beam. A comparison of the measured and calculated relative central-axis depth dose curves in water for 7 MeV beam of (a) 10 × 10 cm2 and (b) 15 × 15 cm2 cones. Measured and calculated cross-beam profiles at the depth of dose maximum in water for 7 MeV electron beam of (c) 10 × 10 cm2 and (d) 15 × 15 cm2 cones. Solid lines indicate measurements data with an ionization chamber (CC13). Squares indicate the calculated data from Monte Carlo simulations
