Abstract

The input couplers and endcells for a previously proposed standing wave muffin-tin structure are designed. Thereby the problem is not only to match the coupler but also to choose the endcells in a way that the coupling cells are not excited. The input coupler has to match the external Q of the structure, to the unloaded Q in order to get zero reflection. The endcells are designed to reflect the forward travelling wave in such a way, that only the accelerator cells are excited and not the coupling cells. The calculation of the endcell behaviour as well as the calculation of the external Q´s are deduced from the knowledge of resonant fields only. The external Q´s are calculated with the Kroll-Yu method
