A Nb3Sn vapor diffusion deposition system was built and commissioned at Jefferson Lab. As the part of the commissioning a single cell 1.5 GHz CEBAF-shaped cavity was coated in the built system. The cavity exhibited the superconducting transition at about 17.9 K. The low field quality factor was about 5x10⁹ at 4 K and 7x10⁹ at 2 K dropping with field to about 10⁹ at both temperatures at about 8 MV/m.
