论文摘要
在建立世界上第一个Mulit-Turn超导能量回收的运行之前，（ERL）配置了Cornell-BNL能量回收测试加速器（CBETA），以进行一个转弯的能量回收。在此设置中，每个主要的Linac腔中的光束负荷直接测量表现出高能量回收效率。具体而言，测量了总的一转功率平衡效率为99.4％，每个腔功率平衡范围从99.2-99.8％。当考虑到返回循环的路径长度调节部分中发生的小颗粒损失时，这对应于每个腔单颗粒能量回收效率的范围从99.8％到100.5％。回收能量的最大电流为70个微型，受到梁挡块初步安装的辐射屏蔽的限制。
Prior to establishing operation of the world's first mulit-turn superconducting Energy Recovery Linac, (ERL) the Cornell-BNL Energy Recovery Test Accelerator (CBETA) was configured for one turn energy recovery. In this setup, direct measurement of the beam loading in each of the main linac cavities demonstrated high energy recovery efficiency. Specifically, a total one-turn power balance efficiency of 99.4%, with per cavity power balances ranging from 99.2-99.8%, was measured. When accounting for small particle losses occurring in the path length adjustment sections of the return loop, this corresponds to per cavity single particle energy recovery efficiencies ranging from 99.8 to 100.5%. A maximum current of 70 microamps was energy recovered, limited by radiation shielding of the beam stop in its preliminary installation.
