Abstract :
Fermilab is developing third a harmonic 3.9 GHz superconducting cavity to improve performances of A0 and TTF photoinjectors. In the frame work of this project we have built and tested two nine-cell copper models and one 3-cell niobium cavity. Properties of the high order modes were carefully studied in a chain of two copper cavities at room temperature. In this paper we discuss results of cold tests of the 3-cell cavity before and after surface treatment.
