FIELD: generation of beams of charged particles or braking gamma-radiation. SUBSTANCE: in accordance with version 1 induction accelerator has accelerating module including two coaxial tubes made of conducting material electrically interconnected on one end and linked to unlike poles of pulse power supply source on the other end. Accelerator has injector and output window close to opposite ends of internal tube forming acceleration chamber. In correspondence with version 2 accelerator has two or more acceleration modules installed in sequence along straight line and connected to one or several pulse power sources and injector and output window are located close to opposite ends of acceleration vacuum chamber formed by way of mechanical vacuum-tight interjoining of internal tubes of acceleration module. Accelerator in agreement with version 3 has two or more accelerating modules installed uniformly along flat curve between curvilinear A C electromagnets and connected to one or several pulse power supply sources and injector and output window are located in taps of acceleration chamber made inside structure. Acceleration chamber includes rectilinear sections in zone of installation of accelerations module and curvilinear sections in zone of installation of A C electromagnets. EFFECT: decreased mass and size characteristics, simplified manufacturing technology, reduced energy consumption, enhanced functional efficiency and ecological safety of accelerator. 3 cl, 3 dwg
