摘要： An industrial compact synchrotron radiation source with improved vacuum to prolong life-time of a charged particle beam. The synchrotron supplies highly stable, intense synchrotron radiation. In the source, a charged particle beam bending duct (1) forming a vacuum chamber through which the charged particle beam circulates, is encompassed by a bending electromagnet (2). At least one SR guide duct (3) for guiding the radiation to the outside extends from the outer circumferential wall (1e) of the bending duct. The SR guide duct is connected through a gate valve (5) to an SR beam line duct (7) for guiding the SR beam to an object to be worked on. A vacuum pump (4) is disposed on the side of the gate valve, close to an orbit (A) of the charged particle beam. The SR guide duct extending from the outer circumferential wall of the bending duct takes the form of a divergent duct which is widened in accordance with a spreading angle ( theta s) of the SR beam travelling through the SR guide duct.

摘要： In a nuclear fusion device having a torus type vacuum shell around which toroidal coils and poloidal coils are wound and arranged and whose interior is maintained in a high vacuum state, the bending rigidity of a shell wall in a circular cross section of the vacuum shell is made higher on the outer periphery side than on the inner periphery side of the circular cross section, thereby to prevent any deformation of the vacuum shell due to a magnetic force and any damage of the shell attendant upon the deformation in a process in which the coils are energized to confine a plasma within the vacuum shell. Moreover, without increasing the inner diameter of the circular cross section of the vacuum shell, the coils are located in proximity to the plasma so as to enhance the plasma producing efficiency.

摘要： PURPOSE:To persue efficiency, and to utilize a magnetic field generated at the central section of a solenoid type coil positively by combining and systematizing a solenoid type superconductive-energy storage device and a conventional pumped storage power facility. CONSTITUTION:A revolving-armature type rotary electric machine 2 utilizing the magnetic field of a solenoid type superconducting coil 1 as an exciting field is installed near the center of the superconducting coil 1. The coil 1 is composed of a superconductive material such as NbTi, Nb3Sn, etc. A strong magnetic field is generated at the central section of the coil 1 in the coil 1 when currents are made to flow through the coil 1. On the other hand, a motor for driving a storage pump in a pumped storage power station prepares an exciting field by a DC power to make a rotor conduct, thus generating torque. Consequently, a uniform magnetic field generated in an SMES can be used as the exciting field of the motor for driving the storage pump. An extremely rational structure in which an exciter is omitted can be adopted regarding a rotary electric machine of a certain kind. Accordingly, efficiency is pursued, and the magnetic field generated at the central section of the coil 1 is utilized positively.

Further, the signal 31 is arranged to control an AC voltage control circuit 23 consisting of thyristors connected in inverse-parallel, so as to determine a voltage level, while the signal 32 is made to control a voltage control element 27 consisting of transistors, so as to rectify pulse form in order to control the primary voltage of a step-up transformer 28. Accordingly, the price can be reduced without using a high voltage quadripole tube as a current control element and also highly accurate control may be carried out.
