D. Barni, C. Pagani, and P. Pierini Received 24 June 2004; published 11 April 2005 Three 6-cell 805 MHz superconducting cavity prototypes for acceleration in the velocity range of about 0.4 to 0.53 times the speed of light have been fabricated and tested. The quality factors (Q0) were between 7×109 and 1.4×1010 at the design field (accelerating gradient of 8–10 MV/m). The maximum gradients reached were between 11 and 16 MV/m; in each case, the Q0 values were ≥3×109 at the maximum gradient. The design, fabrication, surface preparation, and rf testing of the 6-cell cavities are reported in this paper. ©2005 The American Physical Society
