Abstract
PURPOSE: To manufacture an amorphous magnetic alloy material for the magnetic core of a particle accelerator for accelerating or controlling charged particles by subjecting an Fe alloy contg. a specified amount of a vitrifying element to a specified magnetic treatment with heating.
CONSTITUTION: An Fe alloy consisting of 15W30atomic% one or more kinds of vitrifying elements such as Si, P, B, C and Al and 85W56atomic% Fe is used as a magnetic core material showing high-speed magnetization reversal and a large magnetic flux change width for a charged particle accelerator such as cyclotron. This alloy is melted and very rapidly cooled at 104W106°C/sec cooling rate. The resulting amorphous sheet is formed into magnetic core 1, which is then set in electric furnace 4 in a vacuum. After winding coil 3 an electric current is supplied to core 1 to generate sine wave magnetic field H2. Electromagnets 21, 23 are arranged to generate sine wave magnetic field H1 different from field H2 in phase by π/2, and core 1 is heated at a temp. from the Curie point to the crystallization temp. While rotating the synthetic magnetic field of H1, and H2, heated core 1 is slowly cooled so that the induction magnetic anisotropy is made practically isotropic.
