An X-ray image intensifier with a container for accommodating electrodes. According to the present invention, the container (1) and the input screen substrate (3) are basically made of aluminum, wherein the inner wall of the container (1) has An insulating layer (7), on which the electrodes (2) are arranged, the fluorescent material layer (8) is directly coated on the input screen substrate (3), the container (1) and the input screen substrate (3) Preferably made as a whole.
Description
The present invention relates to a kind of X ray image intensifier that has the container that hold electrodes uses.
To disclose a kind of X ray image intensifier tube by EP 0360906 Al, in this X ray image intensifier tube, to have made and assembly fee usefulness in order reducing, electrode system is placed on the inside of the X ray image intensifier tube tube wall between the phosphor screen as lining.This image intensifier tube is made drum shape tube wall by thin plate, and the one end is connected with the input phosphor screen, and the other end is welding on the vitreum, also is provided with an output phosphor screen on this vitreum.An insulating barrier is arranged in the inside of electrode suppor, and this insulating barrier is by lacquer, pottery, glass or preferably constitute by a kind of metal oxide, by spray or brush coated on.Known, electrode suppor also can be by a kind of insulating material, and for example pottery or plastics are made, can cancel the coating insulating barrier in this case.
Disclose a kind of X ray image intensifier tube by DE 4342219 C2, fluorescence coating directly is coated on the support on its input phosphor screen, and this support constitutes input window simultaneously.Support connects together by welding and vacuum chamber.
The objective of the invention is to, design a kind of X ray image intensifier, so that its manufacturing cost and producing cost reduce.
The objective of the invention is such, a kind of X ray image intensifier that has the container of hold electrodes promptly is provided, it has an input screen substrate and a support that is used for cutout screen, container and input screen substrate are to make and be made into an integral body by aluminium basically, wherein the inwall at container has an insulating barrier, settling electrode on insulating barrier, fluorescent material layer directly is applied on the input screen substrate, and support and the container that is made of pottery links together basically.
It is favourable that the input screen substrate of the container of hold electrodes and X ray image intensifier tube is made up of aluminium basically.Can select a kind of simple interconnection technique for identical materials, so that container and input screen substrate vacuum link together hermetically.
If make container become as a whole, can abandon interconnection technique fully like this, and omit a course of work therefrom with the input screen substrate.
If the support of cutout screen is made of pottery, then container can preferably link together with simple mode vacuum-tight and support by friction welding.
Other advantage of the present invention and details can by following to an embodiment explanation and diagram and provide in conjunction with claim, in the accompanying drawing:
Illustrated in figures 1 and 2 is embodiment according to X ray image intensifier of the present invention;
Fig. 3 is an input screen substrate of pressing the X ray image intensifier of Fig. 2.
On X ray image intensifier tube shown in Figure 1, is furnished with a container 1 that is used for hold electrodes 2.The input screen substrate represents with Reference numeral 3 that in the front of container the support of cutout screen 4 is represented with Reference numeral 5.Container 1 and input screen substrate 3 can connect together by welding 6.Inwall at container 1 has an insulating barrier 7 that preferably is made of glaze, settles electrode 2 on this insulating barrier.Electrode 2 can be made by metal or by the polyamide that is rich in carbon black.By the sulfuration zinc-silver of activation, or by the terbium that has added gadolinium oxysulfide, or preferably directly be coated on the input screen substrate 3 by the fluorescent material layer that sodium constituted 8 that has added the caesium iodide.
According to the present invention, container 1 is made by aluminium, and it links together with the support 5 that preferably is made of pottery by friction welding or preferably by ultrasonic bonding.
Within the scope of the present invention, container 1 can be made into and input screen substrate 3 separated components, but preferably container 1 is made into an integral body with input screen substrate 3, can abandon interconnection technique like this.
Input screen substrate 3 is preferably made by aluminium basically, can be made into the enclosed globe shade or the lid shape of an integral body, and preferably connect by gas tungsten arc welding, or plasma welding, or laser welding and container 1 links together.In order to obtain a smooth especially surface, aluminium 9 can be obtained a surface uniformly through the smooth roller of single or double, the crystal structure of fluorescent material layer 8 also is uniformly like this, preferably obtains a coarse-grain structure (Facettenstruktur).
Claims (4)
1. X ray image intensifier that has the container (1) of hold electrodes (2), it has an input screen substrate (3) and a support (5) that is used for cutout screen (4), container (1) and input screen substrate (3) are to make and be made into an integral body by aluminium basically, wherein the inwall at container (1) has an insulating barrier (7), on insulating barrier, settling electrode (2), fluorescent material layer (8) directly is applied on the input screen substrate (3), and the support that is made of pottery (5) links together with container (1) basically.
2. according to the described X ray image intensifier of claim 1, being connected by friction welding or supersonic welding between described support (5) and the container (1) fetches realization.
3. according to claim 1 or 2 described X ray image intensifiers, wherein insulating layer material is a glaze.
4. according to each described X ray image intensifier in the claim 1 to 3, wherein electrode (2) is made by metal or the polyamide that is rich in carbon black.
