MAGNET TO TURN BEAM OF CHARGED PARTICLES Russian patent published in 1995 - IPC

FIELD: acceleration equipment. SUBSTANCE: magnet to turn beam of charged particles has excitation winding 1 enveloped by supports of yoke of return magnetic circuit 2, pole pieces 3, 4 forming inhomogeneous field with decay indices n₁ and n₂ correspondingly. Circular axial trajectory in rotary magnet has turning radius R. Turning angles of particles on local sections with decay indices n₁ and n₂ are equal to ϕ₁ and ϕ₂ correspondingly. AA′ is plane of mirror symmetry of magnet. EFFECT: increased stability of optical parameters of beam of charged particles across output by elimination of linear and angular dispersion in it. 2 cl, 4 dwg
