[発明の技術分野]
本発明は、例えば加速装置等の大型装置に使用される気
密容器にWlする。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention is directed to an airtight container used in a large-scale device such as an accelerator.
[発明の技術的背景とその問題点コ
従来、真空装h′やガス雰囲気炉などに使用される気密

法が行なわ第1ている0
しかしながら、例えば加速装置のような大型の気密容器
に前述のような容器本体の吸蔵ガス除去方法を適用する
ことは、大型の容器本体の内壁を一様稟二高温加熱する
ことは技術的に極めて困難であり、かつ熱効率も悪く、
シたがって、容器本体の吸蔵ガスを十分に除去すること
ができないという不具合がある。[Technical background of the invention and its problems] Conventionally, in an airtight container used in a vacuum chamber h' or a gas atmosphere furnace, the inner wall of the airtight container body is heated using a heat source provided in advance outside or inside the airtight container body. at a high temperature of about 400℃
The first method is to clean and remove the occluded gas by evacuation with a vacuum pump or by flowing clean forming gas while heating. Applying a method for removing occluded gas from a large container body is technically extremely difficult to uniformly heat the inner wall of a large container body at a high temperature, and the thermal efficiency is also poor.
Therefore, there is a problem that the occluded gas in the container body cannot be sufficiently removed.
ところで、容器本体≦−電流を流し、ジュール熱で直接
加熱すれは短時間で効ホよく脱ガスできることが知られ
ているが、一般に使用されている厚肉の容器では、容器
本体の加熱に大電流が必要とされるため実用化されなか
った。一方、容器本体を薄肉の金属発熱体で作り、通電
加熱し易いように製作すれば容器本体の加熱には大電流
を必要としないが、真空容器のため外圧に耐えられない
のでこれも実用化できなかった。By the way, it is known that gas can be degassed effectively in a short time by applying current to the container body ≦ - and directly heating it with Joule heat. It was not put into practical use because it required a current. On the other hand, if the container body is made of a thin-walled metal heating element and made to be easily heated by electricity, a large current will not be required to heat the container body, but since it is a vacuum container, it cannot withstand external pressure, so this is also not practical. could not.
そこで、容器本体を薄肉の金属発熱体で作り、その容器
本体の外側に外圧に耐えるようにシリコン樹脂などの電

あるいは脱ガスに必要な400℃程度の筒温では電気絶
縁層が熱劣化するという不具合があった。また容器本体
の外側に設ける補強ルしてセラミックなども考えられる
がこれでは高fill自二なるという欠点があった。Therefore, attempts have been made to make the container body from a thin metal heating element and to reinforce it by adhering a layer of electrically insulating material such as silicone resin to the outside of the container body to withstand external pressure. The heat @s+- during this process weakens the adhesive strength, causing the electrical insulation layer to peel off and the metal heating element to deform.
Another problem was that the electrical insulating layer deteriorated due to heat at the cylinder temperature of about 400° C. required for degassing. Ceramic or the like may also be considered as a reinforcing layer provided on the outside of the container body, but this has the disadvantage of requiring high fill.
[発明の目的]
本発明は、上記手情に鑑みてなされたもので、その目的

通電加熱に十分に耐え、短時間で良好な排気が可能でか
つ安価C;製作可能な気密容器を提供チるにある。[Object of the Invention] The present invention has been made in view of the above-mentioned circumstances, and its purpose is to sufficiently withstand electrical heating at a high temperature of about 400 °C for degassing the container body, and to produce good results in a short period of time. The purpose is to provide an airtight container that can be evacuated and is inexpensive.

接続する接続フランジを兼ねている。In C2 of the same figure, 1 is a container body made of a thin electric heating element, for example, a titanium plate having a thickness of 0.1 m is formed into an annular shape g1. Reference numeral 2 denotes a reinforcing layer made of a glass compound, which is made by bonding and fixing stones λ, 1, and 1 with glass, and is bonded to the outside of the container body 1 by bonding glass. This reinforcing layer 2 is made by wrapping a string made of grit tile asbestos Mpsst, o11(OH)4 around the outside of the container body 1, and then wrapping a string made of grit tile asbestos Mpsst, o11(OH)4 on the outside of the container body 1, for example, with PbO-BgOB.
- It can be easily manufactured by coating with ZnO-based low melting point glass and heating it in an infrared furnace. Reference numeral 3 denotes a pair of electrodes welded to both ends of the container body 1, which also serve as connection flanges that connect the container bodies.

作が容易である。C2: In order to connect a number of containers constructed as described above through flanges 3.3 at both ends and use them as vacuum conduits for an accelerator, the container body 1 must be degassed. To do this, while evacuating with a pump (not shown),
When a suitable voltage is applied to the electrode 3.3, for example, 18.7 V per meter length of a 0.1-thick titanium container, a current of approximately 17 A per 1 meter width flows through the container body II-, and approximately 10 After a few minutes, the inner wall of the container body 1 can be heated to over 400 degrees Celsius, so the gas is quickly degassed.The container body 1 is fixed to the glass compound layer 2 with glass, It can withstand long-term use because it will not break even if it is heated repeatedly while being pulled.The glass compound layer and the container body are bonded using dibond glass at the same time as the glass compound layer is formed. Farming is easy.

N程度が好ましい。However, the glass compound layer is made of MgO other than asbestos.
, 5i02, AJ20B, etc., is used as the bone material, and a suitable bonding glass is combined with the powder. Further, as the bonding glass, it is preferable to select a bonding glass whose coefficient of thermal expansion is larger than that of the container body in order to obtain strong adhesive strength. A combination of the above-mentioned aggregate and bonding glass can easily be used to create a container body suitable for the container body, or a durable container can be made by overlapping layers of different glass compounds. Furthermore, the container body is made of tantalum Ta other than titanium TI.
, molybdenum MO, tungsten W, stainless steel, etc. may be used.The thinner the wall thickness, the lower the material cost, and in the case of an accelerator that applies a magnetic field, it has the advantage of reducing magnetic loss, but it has the disadvantages of ease of production and airtightness.

ド層は補強層として再生される。On the other hand, the heating of the container body by energization can be freely controlled by the applied voltage, and if external pressure is not applied to the container body g, it is possible to degas the container body by flowing forming gas while heating it to nearly 100°C. When heated with electricity at such a high temperature, the bonded glass of the glass compound will soften and some will melt, but it will be included in the aggregate and there is no risk of the glass compound layer deforming or falling off. When the electricity is turned off and the product is cooled, the glass compound layer is regenerated as a reinforcing layer.

Furthermore, since a glass compound is used as the reinforcing layer 51, and the container body and the glass compound layer are glass-bonded, the coefficient of thermal expansion and adhesiveness can be selected according to the container body. Therefore, a large container with excellent durability can be provided.
