  • Abstract
    Grooved surface is proposed to reduce the secondary emission yield in a dipole and wiggler magnet of International Linear Collider. An analysis of the impedance of the grooved surface based on adaptive finite element is presented in this paper. The performance of the adaptive algorithms, based on an element-element h- refinement technique, is assessed. The features of the refinement indictors, adaptation criteria and error estimation parameters are discussed.
