Abstract :
The fabrication, processing and measurement of five single cell and one 5-cell L-band niobium cavities of elliptical shape are discussed. Q-values of 2 to 5Ã109 have typically been obtained without high temperature firing. In single cells magnetic surface fields as high as 56 mT corresponding to an accelerating field of 7 MV/m have been measured. In the 5-cell structure a gradient of 4.7 MV/m was achieved.
