MedAustron是一个基于同步加速器的强子治疗和研究设施，位于奥地利，目前已进入安装阶段。它是CERNPIMMS设计的一个实现，该设计提出了通过一个电子感应加速器核心将光束感应加速到三阶慢共振提取。主要是为了增加加速器对未来辐照方案的灵活性，同时也作为备选方案，研究了两种替代的提取驱动机制：纵向射频噪声和相位移加速度。解释了其优点以及相应的局限性，并给出了使用二维跟踪代码LONG1D和专门开发的基于Python的仿真代码进行的分析估计和粒子跟踪结果。
MedAustron is a synchrotron based hadron therapy and research facility located in Austria currently entering the installation stage. It is an implementation of the CERNPIMMS design which proposed induction acceleration by a betatron core to the beam into the third-order slow resonant extraction. Primarily in order to increase the accelerators flexibility towards future irradiation schemes but also as back-up options, two alternative extraction driving mechanism have been studied: Longitudinal RF-noise and phase displacement acceleration. The advantages as well as the corresponding limitations are explained, analytical estimates and particle tracking results performed with the 2D tracking codes LONG1D and a specifically developed Python based simulation code are presented.
