9C离子束是双重辐射源于在治疗肿瘤有明显优势。我们用蒙特卡洛程序FULKA模拟了290 MeV/u 9C离子束在水靶中的输运,研究其能量沉积、核碎片分布以及核碎片注量的深度分布,可为9C离子束肿瘤治疗剂量学提供参考。
9C ion beam is a dual radiation source in the treatment of tumors have obvious advantages. We simulate the transport of a 290 MeV / u 9C ion beam in a water target using a Monte Carlo program FULKA to study its energy deposition, distribution of nuclear fragments, and depth distribution of nuclear fragment fluence for the 9C ion beam tumor therapeutic dosimetry for reference.
