Funding: Work supported by the Commission of the European Communities under the 6th Framework Program Structuring the European Research Area, contract number RIDS-011899. In this presentation, we will report on a comprehensive vibration measurement program of a superconducting accelerating module designed for the European X-ray Free Electron Laser (XFEL), currently planned at DESY, at room temperature. This module is a type III, high gradient module which is also the basis of module design for the International Linear Collider (ILC). We will discuss stability within the vessel, for example, cold mass vs. He Gas Return Pipe (GRP), as well as stability along the length of the module. Results of this study may be used for the design of future XFEL/ILC module prototypes. |

Funding: Work supported by the Commission of the European Communities under the 6th Framework Program Structuring the European Research Area, contract number RIDS-011899. The European X-ray Free Electron Laser (XFEL) and the International Linear Collider (ILC) superconducting accelerating modules, containing a string of Niobium (Nb) cavities and a quadrupole, will operate at 2K. In this paper, we will report on the vibration stability studies of a high gradient XFEL/ILC type III superconducting accelerating module quadrupole operating at 4.5K. Measurements are performed via geophones affixed on the cold mass in both horizontal and vertical directions. This data will be compared with piezoelectric accelerometers for the same module. The goal is to study the stability of the cold quadrupole and to compare the results with room temperature conditions. |
