TUPAB146 | Vibration Measurements of Super-Conducting Undulator at SSRF | undulator, data-acquisition, experiment, damping | 1675 |

Funding: Work supported by the National Natural Science Foundation of China (Grant No. 11405255) A Super-Conducting Undulator (SCU) is being built at SSRF. Mechanical stability of SCU is critical to beam stability since the central load is supported by special strings in SCU and the vibration of load will cause directly the vibration of beam. In this paper, vibration results of several key components including central load, cold head, frame support, etc, are studied under different working mode of compressors. The ground vibrations at different distances are compared to get the influence of compressors to SCU. Useful suggestions and possible measures are described to mitigate the vibration and improve SCU stability. |

THPIK001 | Copper Accelerating Structure Fabrication With Controled Cu-Ag Joining Conditions | vacuum, experiment, controls, distributed | 4104 |
|
|||
The paper is devoted to the development of technological processes of copper accelerating structures fabrication from oxygen-free copper. The experimental set-up for vacuum brazing of long accelerating structures with optimal Cu-Ag joining conditions is described. The experimental results of precise machining and subsequent vacuum brazing of Ag-Cu eutectic are presented | |||
