摘要:
Vacuum SHF apparatus comprising a means for forming a charged-particle beam, an accelerating tube for imparting relativistic energies to the charged-particle beam, and a deflection yoke for circular scanning of the beam at an input signal frequency, the accelerating tube and the deflection yoke being arranged coaxially with the beam forming means and successively along the path of the charged-particle beam. The apparatus further comprises an additional magnetic deflection yoke for deflecting the scanned beam outwardly from the longitudinal axis of the apparatus, and an annular travelling-wave resonator. The additional magnetic deflection yoke is preferably made as a cone whose vertex faces the charged-particle beam forming means. The annular travelling-wave resonator is so designed that its broader walls are parallel to the longitudinal axis of the apparatus, the broader walls being provided with annular slots for the charged-particle beam, that has been deflected by the additional deflection yoke, to enter and leave the annular resonator. The annular resonator is provided with means for taking SHF energy therefrom.

Disclosure is made of a charged particle accelerator comprising a high-voltage generator built around a transformer whose primary winding is arranged coaxially inside a sleeve-like magnetic circuit, the secondary winding of said transformer being a sectional winding. Each coil of the secondary winding is connected to one of seriesly connected diode-capacitor rectifier circuits. An accelerator tube is connected to the high-voltage generator. The accelerator tube and the diode-capacitor rectifier circuits are located within the secondary winding of the transformer. The proposed accelerator is small in size, simple in design and easy to manufacture. It is provided with overvoltage protection means to take care of breakdowns and transient processes.
摘要:
A method for irradiation of round-section cylindrical objects, such as pipes, with accelerated electrons, whereby three objects are placed together in the area of intersection of three ribbon or strip electron beams directed at an angle of 120.degree. to one another. The objects in the intersection area are positioned so that the centers of the cross sections thereof coincide with the apices of an imaginary equilateral triangle, and each side of the imaginary triangle being normal to the direction of one of the electron beams, and the length of each side is equal to at least two diameters of an object. The width of each ribbon beam is not less than a triangle side length plus the diameter of an object.
