RF system for VEPP-5 booster ring has been created at Budker INP. It operates at 700 MHz and consists of the RF power source based on KU-393 klystron, waveguide section with wave-to-coax transitions, accelerating cavity, and control system. The cavity higher order modes are damped by resistive loads to eliminate the beam instability. Results of the cavity cold tests and RF system high power level tests are presented.

The paper presents the electron injector for the linear accelerator of TNK facility (Zelenograd). The injector has rather simple design because of realized injection scheme with no prebunching. The beam is divided into bunches directly by the accelerating RF field of the linear accelerator. The injector block diagram is presented, the process of electron beam bunching and acceleration is described.

New industrial accelerator prototype with electron energy up to 5 MeV, average beam power of 300 kW, and duty factor of 14% is under construction at Budker INP. The work is supported by ISTC (Project #2550). At present, the design work is completed, the accelerating structure is under production at INP workshop. The paper presents a general description of the accelerator, its block diagram, and experimental results obtained at recent tests of the accelerating structure and injection unit.
