摘要： PURPOSE:To make magnetic field strength variable in an optional position on an axis by alternately arranging a plurality of permanent magnets and pole pieces of an electron beam focusing magnetic field device and forming some of the permanent magnets to differ from each other in their inside diameter and thickness. CONSTITUTION:In an electron beam focusing magnetic field device using a permanent magnetic material of the same kind but different inside diameter, a permanence coefficient in setting positions of permanent magnets 8, 9 can be increased by enlarging the inside diameters of the magnets 8, 9. With this constitution, magnetic fields at working points of the magnets 8, 9 can be lessened and simultaneously the central magnetic field on an axis is also lessened, and the magnets 8, 9 can be always operated under nearly saturated condition. Further, if the inside diameters of the magnets are lessened, the central magnetic field on the axis intensifies and the same effect is also obtained by varying the thickness.

摘要： PURPOSE:To increase the intensity of the on-axis magnetic field by wrapping a pole piece with a superconductive material, and forming the bore of pole piece from a material with high magnetic permeability. CONSTITUTION:By a bond material 10 a member 9 consisting of superconductive material is adhered to the periphery of the body 2A of a pole piece 2. The base part 2B of this pole piece 2 is made of a material with higher magnetic permeability than the other parts. In a periodic mag. field generating device consisting of the pole pieced 2 and a permanent magnet 1 according to the mentioned constitution, the magnetism to the outside is shut off by the Meissner effect of the superconductive member 9, and further the base part 2B with lesser magnetic resistance is penetrated by a magnetic flux in a comparatively large quantity, so that the on-axis mag. field intensity is enhanced.

摘要： PURPOSE:To interrupt the permeation of a brazing material into an external conductor by connecting an internal conductor with a spiral transmission line surrounded with a magnetic circuit functioning to focus electron beams and surrounding the internal conductor with an external conductor so as to form an coaxial circuit and at that time inserting a sleeve into the lower part of a ceramic window with which the internal and external conductors are fixed. CONSTITUTION:An internal conductor 5 formed perpendicularly to a spiral transmission line 2 and made to pass through a magnetic circuit 1 is connected with an end part of the line 2 surrounded with the circuit 1. A cylindrical external conductor 10 in parallel with the internal conductor 5 is connected with a cylinder inside the circuit 1 so that a coaxial circuit 3 is formed. Terminal parts of them are sealed with a ceramic window 4, and a cap 6 is inserted into the periphery of the window. When this part is sealed with a brazing material 9 thereafter, an upper end part of the external conductor 10 is made larger than conventionally and a sleeve 11 is inserted between the internal conductor 5 and the external conductor 10. When this window block 7 is brazed with the external conductor 10 in this way, the permeation of the brazing material toward the external conductor 10 is interrupted by the sleeve 11, so that a change in impedance of a traveling-wave tube can be prevented.

摘要： PURPOSE:To improve thermal stability in order to obtain an excellent focusing action by using a permanent magnet with a small temperature coefficient, as the one disposed on a place where it becomes high in temperature during their operations, in a periodical magnetic field CONSTITUTION:When electron beams emitted from an electron gun 1 pass the inside of a delaying circuit 2, they are focused into a definite diameter by means of a periodical magnetic field device 4. Ring-shaped permanent magnets 5 used in the device 4 are made of rare earth cobalt. As permanent magnets 9 disposed on a place where it becomes high in temperature during their operations, alnico magnets which are more stable in a thermal property and smaller in a temperature coefficient than the magnets 5 are used. Thus, a change of a magnetic field inside the device 4 placed under a high-temperature atmosphere can be reduced, and an excellent focusing action of electron beams can be always obtained over the whole length of e traveling wave tube.

摘要： PURPOSE:To facilitate the matching operation of impedance between a concentric element an a slow-wave structure by installing a hook hole in an input- output matching element. CONSTITUTION:A matching element 5 has an outer diameter conformable to an inner diameter of a metal cylinder 3 and the preset thickness and, in order to avoid a spiral supporting dielectric rod, installs a notch 6 at a tip end of the spiral insertion side in advance as well as it installs an expanding slot 7 for avoiding an external connecting part of a spiral over the overall length of the matching element 5. In addition, there is provided with a hook hole 8 which is used when its position at the inside of the metal cylinder 3 is changed. With this constitution, the matching of a concentric element, a slow- wave structure and impedance, namely, the setting of a position (taking the matching element in and out) of the matching element is easily performable.

摘要： PROBLEM TO BE SOLVED: To surely emit electrons corresponding to an exactly designed quantity, so as to emit a beam according to a designed orbit by forming an electron emission part and an electron non-emission part at the same time, without a generation of a gap between them on an electron emission surface of an impregnated negative electrode which is composed of a base metal having tungsten and at least BaO impregnated as an impregnant. SOLUTION: It is desirable that one containing one or both of CaO and Al2 O3 , or one containing Sc2 O3 mixed therein or a mixture of W powder and BaO and Sc2 O3 is used as an impregnant. Electrons are emitted by forming a mono-atomic layer of barium on an electron emission surface 4. An impregnated negative electrode 1 integrally has an electron emission part 9 and an electron non-emission part 10 on the electron emission surface 4. The electron non-emission part 10 is formed according to the addition of a prescribed patterned groove or an adhesion of moisture of a surface of the impregnated negative electrode 1 in order to cut off a barium dispersion path based on heating.
