	In 2011 Dubna-Minsk collaboration started an activity on the development and manufacture the series of superconducting niobium cavities in the enterprises in Belarus. First results of this work are presented. Simulation code was developed to compute EM characteristics, and to calculate the shape and geometric dimensions of SC niobium RF-cavity taking into account higher order oscillations modes. The calculations of a single-cell and 9-cell cavity were made: the found ratio of the maximum electric field on the cavity axis to an average accelerating field is 2 within 1%; the found geometric factor equals 283 Ohm. Half-cells will be made by hydraulic deep drawing and welded by electron-beam (EBW). A stamping tool for hydraulic deep drawing of the half-cells and a set of technological tools for probing of EBW of two half-cells have been designed. Mechanical properties of niobium and model material (Cu, Al) were investigated. Cryogenic system for low temperature RF tests of the SC single-cell cavity was successfully tested at 4.2 K. Coupling device for RF measurement of the single-cell SC niobium cavity was synthesized and manufactured – the measured standing wave ratio is about 1.01-1.07. Warm RF tests with etalon single-cell cavity were made: fundamental frequency – 1.273 GHz, quality factor (warm) – 28·10³.
