More about the invention

The invention refers to the particle accelerator equipment and can be used in medicine to treat cancer with protons and to produce different isotopes for nuclear medicine. The engineering result is simplification of beam ejection since a lower intensity on the deflector is needed while accelerator compactness is kept. The shapes of the yoke, magnet sectors, coils in the ejection zone are nonround and repeat the shape of the orbit of accelerated particles. At the edge of the magnet sectors in the ejection zone, a chamfer is made that also repeats the shape of the accelerating particle trajectory.
