加速器是利用电磁场来加速带电粒子的装置 ,如加速电子、质子、离子等。按能量区分 ,加速器分成高能加速器、中能加速器和低能加速器。其中能量低于 10 0MeV的小型低能加速器在医学、工业辐照、离子注入及核分析技术等领域均有广泛的应用。一、加速器在医学上的应用1.疾病的诊
Accelerator is the use of electromagnetic fields to accelerate charged particles devices, such as accelerating electrons, protons, ions and so on. According to the energy difference, the accelerator is divided into high energy accelerator, medium energy accelerator and low energy accelerator. Among them, small low-energy accelerators with energies less than 10 0 MeV are widely used in fields such as medicine, industrial irradiation, ion implantation and nuclear analysis. First, the accelerator in the medical application 1 disease diagnosis
