摘要： PURPOSE:To obtain a variable inductance characteristic which can be used either in a low current circuit or in a high current circuit by forming a movable piece with a superconductor having a high critical magnetic field. CONSTITUTION:As a movable piece 10, a superconductor is used. Since the movable piece 10 rejects magnetic flux, an inductance quantity L viewed from the side of a feeder 2 is deceased when an inserting amount X of the movable piece 10 into a solenoid coil 4 is increased. Since the critical magnetic field of the superconductor is high, the varying characteristic of the inductance is maintained even if the level of a current which is made to flow through the coil 4 becomes high. In this way, the variable inductance characteristic which can be used either in a low current circuit or in a high current circuit is obtained.

摘要： PURPOSE:To enable extremely fast control by providing a shell having an electrical insulating part on the outside circumference of a vacuum vessel and providing plural magnetic or magnetic flux sensors which detect the erroneous magnetic fields generated by the return current flowing along the electrical insulating part. CONSTITUTION:Electric current is passed to plasma 18 and a poloidal magnetic field which is the perpendicular magnetic field in the Z-axis direction shown by an arrow 26 is applied simultaneously thereto from the outside in order to confine the plasma 18. While there is a method of using a poloidal magnetic field coil 20 and a shell 21 to generate such poloidal magnetic field, the functions are shared in such a manner that the shell 21 confines the plasma 18 for a short period of time and the coil 20 for a long period of time. The external poloidal magnetic field coil current is subjected to direct feedback control by measuring the erroneous magnetic field by the magnetic sensor or magnetic flux sensor 22. The eddy current of the shell 21 decreases with lapse of time and the external magnetic field which is the poloidal magnetic field is penetrated by said current, by which the magnetic field is maintained without being changed as a whole and, therefore, the plasma 18 is confined.

摘要： PURPOSE:To enable Ftheta-pumping operation without handling a large amount of electric energy by constituting an Ohmic Heating (OH) coil with two systems of coils respectively supplied with the required current. CONSTITUTION:Plasma current is generated via magnetic field generation and inversion in the region of plasma 1 through a trochoidal coil 5 and the supply of high level DC to the series OH coils 6 of the second system, thereby forming the plasma 1. Then, Ftheta-pumping operation is made to put plasma current in quasi-stationary state. In this case, an OH coil 4 of coaxial construction with the plasma 1 in the first system is supplied with low-level AC current mainly at a zero-level and the surface voltage in the plasma 1 gives an AC change. And electric discharge takes place for a long hour with Ftheta-pumping and the Ftheta-pumping operation can be done without handling a large amount of electric energy, as the drive current of a coil 4 is low-level AC current.
