PURPOSE:To omit a pure water device and the like and to miniaturize and simplify the magnetic- field generating apparatus by arbitrarily controlling the total impedance of the windings by using the conductors with no hollow part, cooling said apparatus by the cooling fluid in a nonmagnetic container, and insulating the windings and the fluid. CONSTITUTION:The fluid is introduced 2 into and exhausted from the annular hermetically sealed container 1 made of nonmagnetic stainless steel. Annular winding containers 4-6 made of the same material are coaxially arranged in said container 1 separately. Insulated and covered flat type conductors 7-9 are wound in the frame 4a-6a and the containers are formed by tightly sealing by outer plates 4b-6b. The lead wires of the windings are connected to terminals 17a- 19b provided on a connecting part 10. The windings 7-9 are connected in series. An epoxy resin 20 is impregnated into the container through the lead wire taking out part under the vacuum state. A separating plate is provided between the winding containers and the hermetically sealed container, thereby the path for the cooling fluid is formed. In this constitution, even though each winding is a conductor with no hollow part, it is sufficiently cooled, the impedance can be arbitrarily set, and the windings and the cooling fluid are perfectly insulated. Therefore, a special cooling device is not required. |
