Abstract

Abstract

Multifunctional cavity(MFC) is one of the most important parts of beam transport system in the “DragonⅠ” LIA. An MFC assembles the flange for vacuum pumps, the drifting tube for electron beam and the BPM for beam diagnostics on line together. Moreover, MFC is convenient to the machine repairing. In this paper, the key points of the MFC design are presented the alignment and repairability are clarified, the continuity of magnetic field is analyzed, the transverse impedance is simulated, and the methods to lower its transverse impedance are presented. The application of MFC has not only simplified the structure of beam transport line, but also improved its performances.
