Abstract:
The inventive device relates to means for X-ray therapy of malignant and non-malignant growths and other diseases and comprises a hollow probe (5), a radiation source (1) of neutral particles irradiated in the form of X-ray or gamma-ray quantum or neutrons and a unit for forming the particle beam of said radiation which is directed along the longitudinal axis of the probe. The inventive means for forming the particle beam is partially embodied in the form of a collimator or a lens (18) which is embodied in the form of a set of curved channels for transmitting radiation with total internal reflection. Said means can be arranged inside the probe (5). The inventive probe is used by introduction thereof into a patient body (11) and bringing the distal end thereof to a pathologic area (13) or by introducing the end directly into said area. In order to affect the pathologic area, the radiation emitted by the source of neutral particles or the secondary radiation excited in a target which is arranged in the distal end of the probe, or the radiation diffused by said target are used. The structure of the inventive device does not require vacuum pumping of the probe and the use of high voltage therein. The structural design is easily transformed by changing the probe, in particular for modifying the dimension thereof, and the energy and direction of the radiation acting on the pathologic area. The demountable embodiment of the probe simplifies the sterilisation thereof.
Abstract:
The inventions make possible to increase the degree of radiation focusing by the lens, to use particles of higher energies, and to increase the coefficients, depending on these factors, of the devices, the lens is used in. Thus the sublens 18 of the least degree of integration represents a package of the channels 5, which is growing out of joint drawing and forming the capillaries, which are laid in a bundle. The sublens of each higher degree of integration represents a package of sublenses of the previous degree of integration, which is growing out of their joint drawing and forming. The sublenses are growing out of performing the said operations at the pressure of the gaseous medium inside the channels being higher than the pressure in the space between the sublenses of the previous degree of integration and at the temperature of their material softening and splicing the walls. To produce the lenses a bundle of stocks (capillaries) in a tubular envelope is fed to the furnace (at the first stage) or stocks, produced on the previous degree, and the said bundle is drawing from the furnace at the speed, exceeding the speed of feeding. The product is cut off on stocks for the next stage, and at the final stage the product is formed by varying the drawing speed, after what the parts with formed barrel-shaped thickenings are cut of.
Abstract:
A device comprise input 6 and output 8 end faces connected with a multitude of channels for transportation of an optical radiation with reflection from their walls. Through the central channels radiation may be transported without reflections. Continuations of the inlet 7 and outlet 9 ends of the channels beyond the input and output end faces of the device are oriented in such a way that in aggregate have shape of input flux of optical radiation perceived by the device, and required output flux, correspondingly. At that, one or both of end faces of the device, except for the inlet and outlet openings of the channels, have non-transparent coating, or the walls of the channels and medium between the channels are non-transparent. When continuations of longitudinal axes of the channels from the side of input and output end faces intersect in points located on continuation of the longitudinal axis of the device, it will be able to focus divergent flux of optical radiation from quasipoint source. When continuations of longitudinal axes of the channels from the side of one of the end faces intersect in point located on continuation of the longitudinal axis of the device, and continuations of longitudinal axes of the channels from the side of another end side are parallel to the longitudinal axis of the device, it will transform divergent flux of optical radiation from quasipoint source into quasiparallel one. The design on the device described ensures separate transmission to the output of radiation energy and corresponding optical information from different elements of input flux created by source of light or illuminated object.
Abstract:
The inventions relate to a group that includes means for directing charged particles, enabling the acceleration and interaction thereof, and producing radiation caused by their movement, namely a method for changing the direction of an accelerated charged particle beam, a device for implementing said method, a source of undulator electromagnetic radiation, a linear and a circular charged particle accelerator, and a collider and means for producing a magnetic field created by a stream of accelerated charged particles. The method and the device for implementing same are based on the use of a curved channel (1) for transporting particles, which is made from a material that is able to be electrically charged, and the formation of the same kind of charge on the inside surface of the channel wall as that of the particles. The characterizing feature of these inventions is that they require the maintenance of a condition that relates the energy and the charge of the particles to the geometrical parameters of the channel, in particular the radius R of curvature of the longitudinal axis (14) thereof, and to the electrical strength of the wall material. The other devices in this group include a device for changing the direction of a beam, which defines the trajectory of the particles inside these devices to produce the required shape according to the function of the corresponding device and focuses the beam. The technical result is the possibility of rotating the beam through large angles without loss of intensity, significantly simplifying the design, and also reducing the mass and dimensions of all the devices, particularly by obviating the need for magnets and supply voltage and control voltage sources for such devices.

Abstract:
The complex, intended for carrying out the researches in the X-ray range at several analytical devices simultaneously, comprises the source 1 of the divergent X-rays, the channels of radiation transporting toward the analytical devices 5 and the apparatus of these devices for spectrometric, diffractometric and other resarches, image formation of the internal structure of the objects, X-ray lithography, etc. The radiation is transported toward the devices 5 as the quasi-parallel beams (4), formed by the X-ray "half" lenses 2, representing a package of the curved channels with the use of multiple total external reflection of the X-rays from their walls. Each of the "half" lenses captures a part 3 of the divergent radiation of the X-ray source 1. An X-ray tube is the preferable type of the source 1. The beams 35 of the radiation, being directed toward several analytical devices 5, can be obtained as well by means of the "half" lens 2, being common for these devices. The output beam 4 of the said "half" lens is split to several beams by means of the monochromators 33, placed on the path of the initial beam 4 at the angle to the direction of the said beam 4 propagation. The said monochromators 33 intercept the part 34 of the cross section of the initial beam. In a specific case the complex can include the "full" X-ray lens 6, focusing the source radiation on the region 22, located on the input of one of the analytical devices 8. The usage of the X-ray lenses provides for the X-rays users in the analytical devices the brightness, being not less than in the complexes, where the radiation source is a synchrotron or a synchrotron storage ring. 1 independent and 26 dependent claims, 10 figures.
Abstract:
With this invention, it is possible to divert or focus beams, convert divergent beams to quasi-parallel beams and vice versa, and to filter and monochromatize beams. Energy losses in radiation transport are reduced, the useful energy spectrum is broadened, and the concentration of the radiation increased. Large-scale sources can be used without any reduction in the proportion of particles captured and the radiation spectrum can be controlled. To achieve this, the method involves, in addition to the repeated reflection of particles as they interact with alternating media of differing densities, the diffused and potential scattering or interference of the particles diffracted by multiple-layer structures created on reflecting surfaces. The proposed device is provided with a coating of such surfaces in layers with differing electromagnetic properties. The optical system is designed preferably as a set of miniature lenses or half-lenses (28) consisting of a plurality of capillaries or polycapillaries; a suitable coating (22) is applied to the walls of the channels (24) of these capillaries. This arrangement eliminates the need for supporting structures for shaping the profiles of the optical system.
Abstract:
The present inventions provide for bending the beams, their focusing, transforming a divergent radiation into a quasi-parallel one, and vice versa, its filtering and monochromatization. There are also attained reduced radiation transfer losses, extended range of energies used, and higher radiation concentration. A possibility is provided for use of larger radiation sources without decreasing the proportion of the captured particles, as well as for controlling the radiation spectrum. With this purpose in view, provision is made in the proposed method, apart from multiple reflection of particles upon interaction with different-density alternating media, also for diffuse and potential scattering or interference of particles that diffract on multilayer structures applied to reflecting surfaces. In a device carrying the proposed method into effect the aforementioned surfaces are coated with layers differing in electromagnetic properties. The optical system of the device appears principally as a set of miniature lenses or hemilenses 28, built up of a plurality of capillaries or polycapillaries, the walls of whose channels 24 are provided with an appropriate coating 22. No use of any support structures for forming the profiles of the optical system is required.
