Percent depth dose measurement. (a)EBT3 and (b) OC1 film irradiated parallel to 9 and 6 MeV beams, respectively. Scale bar is 5 × 1 cm. (c) dose evaluated from EBT3 film irradiated perpendicular to the beam within a water equivalent polystyrene phantom. 6 MeV: red—SSD = 50 cm; 1 pulse; peak dose 7.7 Gy; 9 MeV beams: green—SSD = 20 cm, 3 pulses, peak dose: 9 Gy; blue—SSD = 40 cm, 30 pulses, peak dose 8.5 Gy; purple—SSD = 90 cm, 200 pulses, peak dose 8 Gy; black—SSD = 171 cm 926 pulses, peak dose 7.6 Gy.
