Method and apparatus in a race-track microtron for storing an energy-rich electron beam. Electrons are accelerated by repeatedly passing them through a linear accelerator that is arranged between two bending magnets, which change the electrons path so that they repeatedly pass through the linear accelerator. The electrons thereby move in orbits (3 . . . 8) with a race-track-like configuration and have successively larger orbits. A deflecting magnet (9') and a septum magnet (9'') are arranged in conjunction with the greatest orbit (8). The characteristic features of the invention is that the microtron has a storage ring (10) closed in itself, for accelerated electrons. The storage ring is situated outside the septum magnet (9'') and in the pole gap of each bending magnet (6, 7). A kicker magnet (16) is arranged in the storage ring (10). |
