[en] The design of a new HF system of the VEPP-4M storage ring designated for operation with two electron bunches and two positron ones in colliding beams is described. The HF channel with the frequency of 181.8 MHz comprises 6 accelerating copper resonators. HF power supply of the resonators is realized by a generator, the output cascade of which is produced using the GU-101A tetrodes. At the first stage it is intended to attain the power of 300 kW in the double-valve cascade. Later the generator power will reach 1 mW, which means that the storage ring will be able to with the energy of 6 GeV and current of 4x50 mA. 8 refs.; 1 fig

[en] The HF system for the Sibir'-2 storage ring designed as a specialized source of synchrotron radiation is described. 2 accelerating resonators are installed in the storage ring. The output cascade of the generator is produced with two GU-101A tetrodes. The basic HF system for the frequency of 181MHz is of two-channel type. Auxiliary HF system has a similar structure and operates at the frequency of 541MHz. 8 refs.; 1 fig

[en] The paper has summarizing character. It describes the power HF systems, developed for the VEPP-4 storage ring, for synchrotron radiation storage rings Sibir'-2 and TNK and for the racetrack microtron-recuperator. Main performances and design features of these HF systems and accelerators are described
