摘要： PROBLEM TO BE SOLVED: To detect abnormality of superconducting coil simply with safety by measuring both end voltages of the superconducting coil. SOLUTION: The superconducting coil device 1 includes a superconducting coil 2, a voltage measurement unit 6, a current control unit 7, and a heater 8. When abnormality of the superconducting coil 2 is detected, the superconducting coil 2 is heated by the heater 8, current is applied to the superconducting coil 2 from the current control unit 7. If both end voltages of the superconducting coil 2 exceeds a predetermined threshold, the voltage measurement unit 6 determines that the superconducting coil 2 is abnormal.

摘要： PROBLEM TO BE SOLVED: To provide a flywheel generator controller which controls input and output of power of a flywheel generator properly. SOLUTION: A pattern set means 10 outputs a load power pattern so as to satisfy a demand pattern which a load 7 connected to the receiving-end bus-bars 3 of a power system requires. A power control means 11 computes a reference frequency value for AC excitation of an exciter 8 on the occasion of the load power pattern, and outputs it to the exciter 8 through a reference value outputting means. The exciter 8 performs AC excitation of the flywheel generator 1 based on the reference frequency value, and controls the input and output of the flywheel generator 1.

摘要： PURPOSE:To prevent damage of a beam damp by furnishing a main magnet, which is arranged along a neutral particle beam line and deflects an ion beam advancing together with the neutral particle beam, and an aux. magnet which further leads the deflected ion beam to the specified direction. CONSTITUTION:A main magnet 1 is provided with a magnetic pole 1a. and a coil 1b wound around this magnetic pole 1a is installed. Approx. perpendicularly to the main magnet 1, an aux. magnet 2 is installed which deflects the ion beam once deflected by the main magnet 1 further using Rorentz's force and leads to the specified direction. The aux. magnet 2a is provided with a magnetic pole 2a, and another coil 2b wound around this magnetic pole 2a is installed. Further a beam damp 3 is installed approx. parallel to the aux. magnet 2. Thereby the ion beam 4 is bent as returning to the neutral particle beam 5 side, put incident on the heat receiving surface of the beam damp 3, and converted into a heat energy to be carried away.

摘要： PURPOSE:To drastically increase the current density of ion and minimize the size of whole components including a neutralizing cell by bending the ion beams extracted out of a plurality of ion sources to the same direction and injecting in an acceleration part. CONSTITUTION:Ion beams extracted out of a plurality of ion sources 1 are bended to the same direction with a magnetic field formed by a toroidal coil 2 and injected in an acceleration part 3. The injected ion beams overlap and accelerate each other and therefore, the current density introduced into a neutralizing cell 4 can be drastically increased. Resultingly, the inlet area of the neutralizing cell 4 can be reduced, the length of the neutralizing cell 4 can be shortened, and the whole components can be small-sized. Instead of the toroidal coil, a toroidal coil shape magneic field can be formed with electromagnets or parmanent magnets.

摘要： PURPOSE:To make it needless to specially supply a control power from outside and to make a transformer for power supply unnecessary by using light energy and energy obtained from a DC power source as the energy in a commutation circuit. CONSTITUTION:With the ignition of a first optical element 5 by the light energy, the DC current is supplied from a DC power source 1 to a load 12 and the energy from the DC power source 1 is accumulated in an energy accumulation means 6 in the commutation circuit Cc. When a second optical element 9 is ignited with the light energy, the energy stored in the energy accumulation means 6 flows to the first optical element 5 as an opposite direction current so as to break the first optical element 5 and the power supply from the DC power source 1 to the load 12 are broken. Thus, it is not needless to supply the control power and the transformer is not needed, so that the stray electrostatic capacity is reduced.

摘要： PURPOSE:To miniaturize a surge energy absorbing element, by a method wherein a core of the surge energy absorbing element is constituted to interlink with only an output path of a source plasma power source and not with a high voltage output path of an acceleration power source. CONSTITUTION: A DC high voltage power source unit supplies power to an ion source 1 as load, and converts AC voltage into DC voltage through a transformer 3 and an acceleration power source 2 and supplies the DC voltage to an acceleration electrode 1b through a DC high voltage cable 5. A deceleration power source 7 is connected to the electrode 1b, and a source plasma power source 8 is connected to a filament 1c through a surge energy absorbing element 10. In this case, the absorbing element 10 is made not to interlink with high voltage side of the DC high voltage cable 5, and a surge suppressing element 6 in parallel circuit of a resistor and a reactor is connected to side of the ion source 1 of the cable 5. Thus discharge current from capacitance can be suppressed to small value.
