Abstract
The utility model relates to an end window type supersoft X-ray tube, comprising a vacuum insulating shell and a corresponding cathode component and a corresponding anode component. A beryllium base metal sheet is arranged at an opening of the end part of the vacuum insulating shell towards to the direction of the cathode electron current; and the beryllium base metal sheet is communicated with the anode component to form an X-ray input window. The beryllium base metal sheet can excite supersoft X-ray with longer wave length after being impacted by cathode electron flow; the radiation main direction of the X-ray is consistent with the direction of the cathode electron flow; a ray channel does not have barriers, the radiation angle is large, and the end window type has simple and compact structure and is convenient to the miniaturization of instrument.
Description
Technical field: the utility model relates to a kind of X ray generator tube.
Background technology: present X-ray tube all is to utilize cathode stream bombardment anode head with angle, and the reflection back, X ray inclination angle of generation passes from the side of vacuum insulation shell, constitutes the emitting structural of the window formula of inclining.The ray tube volume of this structure is big, is not easy to miniaturization, and the X ray that its side penetrates is subjected to each parts to block restriction, and angle of radiation is less, wayward adjusting.And the X ray wavelength that this window ray tube that inclines produces is very short, and not enough " soft " though the transillumination ability is better, is not easy to be absorbed by object blocks very much.In fields such as printing, chip manufacturing, organic solvent or ammunition encapsulation, often need to utilize the absorption of air X ray to produce ionization, to eliminate static or explosion-proof, cross short wavelength's X ray and can't use.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of wavelength longer, the end-window super-soft X-ray pipe that angle of radiation is bigger.
The utility model comprises vacuum insulation shell and corresponding cathode assembly and anode component, on the vacuum insulation shell, towards the open-ended place of cathode electronics flow path direction, covering is provided with beryllium Base Metal sheet, and this beryllium Base Metal sheet and anode component conducting constitute the X ray output window.
After beryllium Base Metal sheet of the present utility model is subjected to the cathode stream bombardment, can inspire the super-soft X-ray of longer wavelength, the main direction of radiation of X ray is consistent with the cathode electronics flow path direction, ray channel does not stop, angle of radiation is big, and this end-window is simple and compact for structure, is convenient to instrument miniaturization.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: accompanying drawing is the main structure schematic diagram of embodiment.
Embodiment: as shown in the figure, cathode assembly 2 in the vacuum insulation shell 1 is corresponding with anode component 3, on vacuum insulation shell 1, towards the open-ended place of cathode electronics flow path direction, hide and be provided with beryllium Base Metal sheet 4, this beryllium Base Metal sheet 4 and anode component 3 conductings constitute the X ray output window.General beryllium Base Metal sheet 4 and electron stream direction, promptly the main shaft of ray tube is vertical, can certainly be obliquely installed.
When energising work, the electron stream direct projection beryllium Base Metal sheet 4 that cathode assembly 2 produces, can excite after beryllium Base Metal sheet 4 is bombarded and outwards give off the super-soft X-ray that wavelength is 1-30 dusts, this X ray is easy to be produced ionization by absorption of air, in fields such as printing, chip manufacturing, organic solvent and ammunition encapsulation, the negative ions group that can utilize ionization to produce very easily eliminates static, and effect is good.
Because the main direction of radiation of the X ray that produces is consistent with the cathode electronics flow path direction, and ray channel do not stop that the angle of radiation of Chan Shenging is bigger like this, can reach 160 and spend.Present embodiment also is connected with adjustable ring 5 at X ray output window place, constitutes X-radiation angle control structure.Because super-soft X-ray is easy to be blocked, by changing the caliber size of adjustable ring 5, perhaps the axial length of adjustable ring 5 is easy to angle of radiation is limited adjustment, and bore is more little, axial length is long more, and angle of radiation is just more little.In the reality, adjustable ring 5 can with the anode component 3 formula structure that is combined into one, compact more, and can not influence performance.The port shape of general adjustable ring 5 can be circle or polygon, is convenient to the calculation control radiation angle, also can be various other shapes as required certainly.
