论文摘要
在本文中，我们证明可以使环状体在宽的能量范围内具有恒定的betatron曲调。特别是，我们表明可以使水平曲调稳定，并且不必遵循洛伦兹因子伽玛（Lorentz Factor Gamma），同时仍然完全满足了相应条件。为了进行此演示，我们基于Betatron曲调的计算，完全是根据逼真的非硬边封闭轨道的几何形状的计算来开发的。我们提出了两种特定的回旋器设计，一种紧凑型回旋子和一个环回旋体。紧凑型回旋器设计由三维有限元磁铁计算来支持，我们也在此处介绍。
In this paper we demonstrate that cyclotrons can be made to have precisely constant betatron tunes over wide energy ranges. In particular, we show that the horizontal tune can be made constant and does not have to follow the Lorentz factor gamma, while still perfectly satisfying the isochronous condition. To make this demonstration we developed a technique based on the calculation of the betatron tunes entirely from the geometry of realistic non-hard-edge closed orbits. We present two particular cyclotron designs, one compact cyclotron and one ring cyclotron. The compact cyclotron design is backed up by a 3-dimensional finite element magnet calculation, that we also present here.
