%0 Journal Article %T Superconducting elliptical cavities %A J. K. Sekutowicz %J Physics %D 2012 %I arXiv %X We give a brief overview of the history, state of the art, and future for elliptical superconducting cavities. Principles of the cell shape optimization, criteria for multi-cell structures design, HOM damping schemes and other features are discussed along with examples of superconducting structures for various applications. %U http://arxiv.org/abs/1201.2598v1
