SBIR Phase I: Accelerating-Focusing Rectangular Cavity Structures

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，以确定其商业用途的适用性。这些应用范围从赛道微管（RTM）到电子正电子线性对撞机以及微波功率器件。一个70兆电子伏的紧凑型RTM将被用作一个实际的测试平台，首先将概念想法转化为实践。研究了一种带圆梁孔的双周期轴向耦合矩形加速结构。这大大简化了RTM的构造。该RCBS还具有比以前结构和四极聚焦更高的有效分流阻抗，因此它是一种加速聚焦系统，如果经过仿真和硬件验证，也可以用于线性加速器和线性对撞机。近年来，粒子加速器的设计工作主要集中在改进现有的加速结构，寻找更紧凑的结构，以及开发具有更好电动力特性的结构。矩形腔结构的商业应用是显而易见的：(1)正电子直线对撞机，(2)电子直线加速器，(3)移动赛道微管，(4)功率微波器件。

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.
