Abstract

PURPOSE:To enable a fan-shaped molded coil to be easily molded, by applying a butt rod having a curvature to the bottom part of laminated metal plates for coil, and placing two round rods at the upper part of the metal plates for coil, and placing an upper mold having a recessed part of the same curvature, and then making a space between two round rods expand. CONSTITUTION:A coil 1 to be molded which is made by successively laminating metal plates for coil and insulators each molded by square-shape punch is applied to the upper part of a butt rod 2 on a lower mold 6. In this case a sectional area of this laminated coil 1 is made to be in a reverse trapezoidal shape. Then, round molding rod 3A and 3B are placed at the upper part of the coil 1, with an upper mold 5 placed thereon, and a press mold 7 is set to be squeezed between the round molding rods 3A and 3B. and the press mold 7 is made to advance to make a space between the round molding rods 3A and 3B expand along the recessed part 4 of the upper mold 5. Thus, the molded coil 1 is gradually bent in a circular-arc shape along the curvature of the press rod 2 so that the molded coil 1 can be completed with its sectional area being in a fan shape.

For example, Li can be used as an elementary particle beam acceleration system such as protons.
Research equipment called nac has been proposed at various research institutions. Among these, quadrupole magnets are used for beam focusing, and although electromagnetic and permanent magnet types have been proposed, quadrupole magnets require a large magnetic field gradient for the magnetic poles. On the other hand, one of the requirements is to minimize the installation space.

In view of this, the present invention improves the efficiency of the 4-pole magnet by constructing it with a metal plate with a large cross-sectional area in order to allow a larger current to flow, since there is a limit to the current that can be passed through conventional wire winding. In order to achieve this, the outer periphery of the 4-pole magnet F is made circular, and in order to further improve electromagnetic efficiency, all the laminated metal conductors for the coil are formed into fan shapes with the same curvature, thereby greatly improving the conventional installation space. The main purpose is to propose a manufacturing method.
