Abstract: The charged particle storage system includes: a storage ring circulating, by a perturbating device, charged particles injected from outside; a power source supplying an electric current to the perturbating device; and a charged particle beam generating device. The charged particle beam generating device includes a DC accelerator that generates a constant voltage to accelerate electrons and thereby generates a beam of the electrons. While a current having its current intensity changing in a sinusoidal wave is caused to flow through the perturbating device continuously for at least 10 ?s by a power source, an electron beam output from the charged particle beam generating device is injected to the storage ring continuously for at least 10 ?s. Thus, a current larger than that stored by the conventional resonance injection method can be stored in the storage ring, and an X-ray having higher intensity can be generated.

Abstract: A blade mount is attached or detached without bolts to save the time for the attaching and the detaching. Consequently, the operation efficiency of the rotary die cutter is enhanced, which is intended to achieve. Two fixing rings are freely fitted to a knife cylinder and the driving unit rotates the screw axis to move moving mounts. Thereby, yoke plates disposed on the moving mounts move the fixing rings to the end portion of a blade mount, and then an activated unit activates fixing units to fix the fixing rings to the outer circumference face of the knife cylinder, so that the blade mount is fixed. After the fixing rings are fixed, the yoke plates are separated from the fixing rings, so that abrasion of the yoke plates can be avoided.

Abstract: It is intended to improve work efficiency by eliminating the work of attaching and removing push rods during installing and dismounting the a blade mount and also to reduce abrasion of the push rods for pushing punching scrap out of a punching blade. The first push rods 18 are inserted movably in the first through-holes 16 formed in the knife cylinder and the second push rods 36 are inserted movably in the second through-holes 34 formed in the blade mount to permit the second push rods 36 to be abutted on the first push rods 18. A scrap push lever 30 is mounted on the outer end of the second push rod 36 to push out the punching scrap a and an eccentric cylinder 14 is provided inside of the knife cylinder 10 to push the first push rod 18 outward when pushing out the punching scrap a. The stroke of the first push rod 18 is controlled so that the outer end 18a of the first push rod 18 does not project from the outer periphery 10a of the knife cylinder.

Abstract: A blade mount is brought into contact with the outer circumference face of knife cylinder such that penetrating hole having a larger diameter on the blade mount faces a stopping member of sliding member. Resilient force is generated between an active-force generator and the sliding member and thereby the stopping member is projected externally from the outer circumference face of the knife cylinder. The blade mount is slid with respect to the outer circumference face of the knife cylinder such that the inner wall of penetrating hole having a smaller diameter formed on the blade mount is fitted into the space between the outer circumference of the knife cylinder and the stopping member, so that the blade mount is fixed to the outer circumference face of the knife cylinder.

Abstract: A perturbation device for a charged particle circulation system, capable of readily generating a distribution profile of a perturbation magnetic field, is provided. By partially superposing a perturbation magnetic field on a main magnetic field for circulating charged particles, perturbation is produced in trajectories of the charged particles. Then, the charged particles that have been injected into the charged particle circulation system are captured into a stable circular closed orbit. Using a leakage magnetic field formed of a magnetic field generated by magnetic field generation devices, each including a high-frequency coil, the perturbation magnetic field is generated.

Abstract: The present invention relates to a high-energy X-ray imaging device that is suitable for precise medical diagnosis and capable of enhancing the accuracy of nondestructive examinations. The high-energy X-ray imaging device of the present invention includes an electron-circulating type high luminance X-ray generator and a two-dimensional X-ray detector that is sensitized for high-energy X-rays. The electron-circulating type X-ray generating device consists of a tinytarget together with a LINAC or microtron injector and a synchrotron. The synchrotron stores electrons, and electrons are bombarded against a tinytarget placed on the electron orbit to generate high-energy X-rays. The means to sensitize the two-dimensional X-ray detectors consists of a thin film made of lead or other heavy elements. This thin film is placed in front of and in close contact with the two-dimensional detector, such as X-ray film. The X-ray image thus generated is a transmissive image.

Abstract: In a method of generating radiation, a gas having a pressure equal to or greater than 10.sup.-9 Torr is introduced into an electron orbit in an electron storage ring. The gas is ionized by a circulating electron beam, and the electron beam is focused by ions to accumulate a large current electron beam. Also, a target is disposed on an electron orbit in the electron storage ring, and the electron beam circulating along the electron orbit is caused to hit the target, thereby generating a bremsstrahlung and high-intensity radiation.

Abstract: Long-wavelength light is introduced into an electron orbit capable of storing high-speed electrons to produce inverse Compton scattering to scatter short-wavelength light to provide short-wavelength light. The introduced long-wavelength light is repeatedly reflected and repeatedly touches the electron orbit. The effective collision cross section of the introduced light with electrons can be substantially increased by increasing the number of collisions. Sufficiently short-wavelength light can be obtained by a small-sized apparatus without making the electron energy very high.

Abstract: In a photon storage ring for storing SR light to generate the same through an outlet port, a reflection mirror is disposed to surround a circular orbit along which bundles of charged particles revolve at a speed close to the velocity of light, generating SR light at a direction tangential to the circular orbit. The reflection mirror has curvature such that the SR light generated in the tangential direction is reflected on the reflection mirror and sent as reflection SR light which is tangential to the orbit. The SR light and the reflection SR light interfere with each other and are guided towards the outlet port.
