Abstract

Abstract A 140GHz 4MW long pulse ECRH system for the experimental advanced superconducting tokamak (EAST) has launched in 2011. The waveguide (WG) bellows is an important component in transmission lines, which can absorbs the axial deformation caused by thermal expansion. The flexible WG inside WG bellows dominates bellows performance. In this paper the mechanical analysis including stress analysis and error analysis for flexible WG is presented in detail. A prototype of the WG bellows has been designed and fabricated.
