SOURCE OF PENETRATING RADIATION Russian patent published in 1994 - IPC

FIELD: acceleration equipment. SUBSTANCE: source of penetrating radiation has backward magnetic circuit 1, unit 2 of central inserts with air gap σ_a, poles 9, 10 in the form of central core and profile part separated with circular slot 11 in which bias winding 6 with inductance L_b is dropped. Slot width is chosen within limits (1.1-1.5) σ_a which excludes redistribution of fluxes from one magnetic circuit into another and its depth does not exceed height of pole. Source of penetrating radiation also includes magnetization winding 5, commutating device 7 and current conduit with inductances L_mw and L_d correspondingly. L_d< L_b< L_mw that is why discharge of reservoir capacitor 4 through bias winding 6 does not cause heating of cable connecting magnetization winding 5 and bias winding 6 to reservoir capacitor 4. EFFECT: improved operational characteristics. 2 dwg
