CYCLOTRON, MAGNET COIL AND ASSOCIATED MANUFACTURING PROCESS

摘要

A cyclotron and associated magnet coil and coil fabricating process. The cyclotron (10) includes a return yoke (12) defining a cavity (28) therein. A plurality of wedge-shaped regions called "hills" (29) are disposed in the return yoke (12), and voids called "valleys" (34) are defined between the hills (29). A single, substantially circular magnet coil (40) surrounds and axially spans the hills (29) and the valleys (34). The cyclotron magnet coil fabricating process includes the steps of securing a first end portion of a continuous length of sheet conductor to a substantially circular base, and positioning a first end portion of a length of insulator material coated on opposite sides with a thermosetting resin between the first end portion of the sheet conductor and the base. The length of sheet conductor and the length of insulator material are then wound about the base, and the magnet coil is heated to a temperature sufficient to cause the thermosetting resin to flow and wet adjacent turns of the sheet conductor.
