Abstract：
This paper reported a new shape of practicing single-cell superconducting cavities. It consist of the two half end-cell of 9-cell Beijing TESLA shape accelerating cavity. The ratio of the maximal surface electric field to accelerating gradient,E_p/E_acc,of the π-mode of the 9-cell cavity is reduced to 2.024. The cell -to-cell coupling k is high to 1.95%. The E_p/E_acc in the single-cell cavities is reduced to 1.8.The monopole, dipole and quadrupole high-ordermodes, HOM, was calculated with resistance-band model using URMEL-T. In addition, the concept of the structure parameters of niobium cavity was introduced as well as the condition of calculation reliability with codes, URMEL and URMEL-T, was discussed.
