Method of manufacturing coils for use in charged particle deflecting electromagnet
First Claim
1. A method of manufacturing coils for use in charged particle deflecting electromagnets, said method comprising the steps of:
- forming a plurality of flat coils including forming a plurality of right-handed flat coils and a plurality of left-handed flat coils, each of the right and left-handed flat coils being formed by winding a conducting wire outwardly from a reference point and fixedly adhering the conducting wires to each other, each flat coil including an inner diameter portion disposed on an inner diameter side of an arcuate path of charged particles, an outer diameter portion disposed on an outer diameter side of said path, and coil end portions located at two sides of said inner an outer diameter portions for connecting said inner an outer diameter portions with each other;
forming coil units by bending the two coil end portions of each of said flat coils in a direction opposite to said path such that they oppose each other;
stacking a predetermined number of coil units;
adhering the stacked coil units to one another; and
electrically connecting the stacked coil units.

Abstract
A coil is provided for use in a deflecting electromagnet in which two coil end portions are bent as well as a method of manufacturing the same. In the coil, a plurality of coil units in each of which two coil end portions 3c are bent such that they oppose each other are laid on top of one another, and the individual coil units are electrically connected to each other. Alternatively, two-layer coil units in each of which the two ends of the conducting wire are located on the outer side of the outer diameter portion of the coil unit are laid on top of one another, so that all the connecting portions of the conducting wires between the individual two-layer coil units can be located on the outer side of the outer diameter portions. Alternatively, the connecting portions of the conducting wires between the individual coil units are extending such that they are separated from the coil unit.

2. A method of manufacturing coils for use in charged particles deflecting electromagnets, each of said coils being formed by stacking a plurality of two-layer coil units, each of the two-layer coil units being formed by winding a conducting wire having a length corresponding to two layers such that two ends of the conducting wire having a length corresponding to two layers such that two ends of the conducting wire are located on an outer peripheral portion of the coil unit, said method comprising:
-
forming the plurality of two-layer flat coils each of which has an inner diameter portion disposed on an inner diameter side of an arcuate path of charged particles, an outer diameter portion disposed on an outer diameter side of said path, and coil end portions located at two sides of said inner and outer diameter portions for connecting said inner and outer diameter portions with each other, said step of forming the two-layer flat coil including steps of forming a first layer flat coil by winding half of a single conducting wire having a length corresponding to the two layers from an intermediate portion of the wire outwardly from a reference point in one direction, and forming a second layer flat coil by winding the remaining portion of the conducting wire from the intermediate portion of the wire outwardly from the reference point in the other direction, said two steps of forming the first and second layer flat coils being repeated to form the plurality of the two-layer flat coils; forming two-layer coil units by bending the coil end portions of each of the two-layer flat coils in a direction opposite to said path such that they oppose each other; laying the plurality of two-layer coil units on top of another in a predetermined order; and electrically connecting ends of the conducting wires of the two-layer coil units which are laid with each other. - View Dependent Claims (3, 4, 5)
