Abstract：
This paper designed a 9—cell RF superconducting accelerating cavity for the TeV electron linear accelerator collider in next century.The ratio,E_pk/E_acc,of the maximal surface electric field to the accelerating gradient has been reduced to 2.024 and the cell to cell coupling keeps high to 1.95%.Distribution of the HOM passbands is reasonable.There is no overlap between the bands,therefore no trapped modes.The CSE type structure guarantees the mechanical hardness.According to present state of the art technigue of Niobium surface processing,it is possible to reach 25—30MV/m for the accelerating gradient with beam load.
