SBIR Phase I: Accelerating-Focusing Rectangular Cavity Structures

这个小型企业创新研究第一阶段项目是加速聚焦矩形腔周期结构和矩形腔双周期结构(RCBS)的设计/可行性研究，以确定它们在商业用途中的适用性。这些应用范围从赛道微加速器(RTM)到电子正电子线性对撞机以及微波功率设备。一台70 MeV的紧凑型RTM将被用作一个实用的试验台，首先将概念转化为实践。探索了一种带圆形束孔的双周期轴向耦合矩形加速结构。这大大简化了RTM的构建。这种RCBS还具有比以往结构更高的有效分流阻抗和类四极聚焦，因此它是一种加速聚焦系统，如果经过仿真和硬件验证，它也可以用于直线加速器和直线对撞机中取得良好的效果。最近在粒子加速器设计方面的努力集中在改进现有的加速结构，寻找更紧凑的结构，以及开发具有更好的电动力学特性的结构。矩形腔结构的商业应用在(1)电子-正电子直线对撞机、(2)电子直线加速器、(3)移动赛道微加速器和(4)功率微波器件中是显而易见的。

This Small Business Innovation Research Phase I project is a design/feasibility study of accelerating focusing Rectangular Cavity Periodic Structures and Rectangular Cavity Biperiodic Structures (RCBS)to determine their applicability for commercial uses. Those applications range from Race Track Microtrons (RTM) to electron positron linear colliders as well as for microwave power devices. A 70 MeV compact RTM will be used as a practical test bed to first reduce concepts ideas to practice. A biperiodic on axis coupled rectangular accelerating structure with circular beam holes will be explored. This provides a significant simplification in RTM construction. This RCBS also has a higher effective shunt impedance than previous structures and quadrupole like focusing so it is an accelerating focusing system which, if proved in simulation and hardware, can also be used to good effect in linacs and linear colliders. Recent efforts in particle accelerator design have focused on improving existing accelerating structures, searching for more compact structures, and developing structures with better electrodynamic characteristics. Commercial applications of rectangular cavity structures are apparent for (1) electron-positron linear colliders, (2) electron LINear ACcelerators, (3) mobile Race Track Microtrons, and (4) power microwave devices.
