【考案の詳細な説明】
本考案は、荷電粒子加速装置のイオン源、電磁

めの冷却装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cooling device for cooling equipment installed in high voltage parts such as an ion source and an electromagnet of a charged particle accelerator.
荷電粒子加速装置のイオン源、電磁石などの機
器は、例えば100KV〜1000KV（DC）もの高電圧
部位に設置されるが、この種加速装置を効率よく
運転するには、これらイオン源等を冷却する必要
がある。このため従来は低電圧部位からの冷却液
を配管などを介してイオン源等冷却されるべき機
器（以下、被冷却体という）に循還供給するよう
にしている。この場合、高電圧部位近傍の流路と

μA〜数百μA以下）でなければならない。一例を
あげると、冷却液として純水を用いる場合、
300KV（DC）の高電圧で使用できるようにする
ためには、チユーブ口径が20φmmのものを用いる
とその長さは15ｍ必要となる。 The ion sources, electromagnets, and other equipment of charged particle accelerators are installed in high voltage areas of, for example, 100KV to 1000KV (DC), but in order to operate this type of accelerator efficiently, these ion sources, etc. must be cooled. There is a need. For this reason, conventionally, a cooling liquid from a low-voltage part is circulated and supplied to equipment to be cooled (hereinafter referred to as a cooled object) such as an ion source via piping or the like. In this case, an insulating tube is used as the flow path near the high voltage part, but it must be able to withstand high DC voltage, including the cooling fluid. Furthermore, the leakage current must also be extremely small (for example, several μA to several hundred μA or less). For example, when using pure water as a coolant,
In order to be able to use it at a high voltage of 300KV (DC), if a tube with a diameter of 20mm is used, its length will need to be 15m.
さて、従来のこの種装置は、第１図に示すよう
に、被冷却体１を収納した高電圧ケージ２を搭載

ル、９はベース、１０はポンプ、１１は熱交換
器、１２は液体配管である。 Now, as shown in FIG. 1, in a conventional device of this kind, an insulating tube 4 is attached to a predetermined length on an insulating support, for example, a support insulator 3, on which a high voltage cage 2 containing a cooled object 1 is mounted. The cooling liquid 6 from the cooling liquid source 5 is supplied to the object to be cooled 1 through the tube 4. In the figure, 7 is a DC high voltage power supply, 8 is a high voltage cable, 9 is a base, 10 is a pump, 11 is a heat exchanger, and 12 is a liquid pipe.
而して、荷電粒子加速装置は、一般に空調され

型化される傾向にあり、従つて建屋の内容積も大
となり、必然的に空調スペースも増大する。この
結果、費用的な面などより必らずしも完全な空調
が行なえず、従つて建屋内の湿度を十分下げ得な
いことが生ずる。 Charged particle accelerators are generally installed in air-conditioned buildings, but in recent years, this type of equipment has tended to become larger, and the internal volume of the building has also increased, which inevitably requires air conditioning. Space also increases. As a result, it is not always possible to perform complete air conditioning due to cost reasons, and therefore the humidity within the building cannot be sufficiently lowered.
このため、加速装置周辺の空気中の水分が冷え

が加わり、貫通放電を起すなどしてチユーブ４に
穴があいたり、これらに起因して被冷却体を損傷
することがあつた。 For this reason, moisture in the air around the accelerator condenses on the outer surface of the tube 4 through which the cooled coolant 6 passes, forming water droplets, causing creeping discharge on the outer surface of the tube 4 to which high voltage is applied, and Since it touches the surface, dust naturally adheres to it. When a water droplet flows, a portion of the same potential is generated along the length of the tube on the outer surface of the tube, but on the inner surface,
Since the voltage is almost equally divided, the inside and outside of the tube have different potentials, and abnormal voltage is applied in the thickness direction of the tube 4, causing a through discharge, which may cause a hole in the tube 4. Damage to the object to be cooled occurred.
本考案者は、高電圧が印加されているチユーブ

決するようにしたものである。 The inventor believes that the above-mentioned discharge is caused by the fact that the tube to which high voltage is applied is exposed to the air, and the above-mentioned abnormal voltage is applied directly in the thickness direction of the tube. Focusing on
Most of the tube is housed in a container filled with insulating gas, fittings are provided at both ends of the tube, and the fittings and the lid of the container, which are on the same voltage side, are electrically identical. The above-mentioned problem is solved by connecting them so that the potential is the same.

する接続線である。 Hereinafter, the present invention will be explained based on an embodiment shown in the drawings. In FIG. 2, reference numeral 13 denotes a container for housing the tube 4, which is provided, for example, at the bottom of the high-pressure cage 2. FIG. 3 shows the structure of the container 13 and its surroundings.The body 14 is made of an insulating material such as resin, and has lids 15 and 16 made of metal plates on the top and bottom. and container 1
For example, a winding frame 17 is provided inside the tube 3, and an insulating tube 4 through which a cooling liquid 6 such as insulating oil, Freon liquid, or pure water is passed is wound and housed. , 4b are inserted through the lids 15 and 16, respectively, and drawn out of the container 13. In addition, 18 is a presser metal fitting. and,
The inside of the container 13 is once evacuated via a valve 19, and then an insulating gas 20 such as SF 6 gas, N 2 gas, CO 2 gas, etc. is filled at a predetermined pressure. 21 is a joint fitting, 22 is a liquid pipe on the cooling liquid source side, and 23 is a liquid pipe on the side of the object to be cooled. Reference numeral 24 indicates the joint fittings 21, 21 and the lids 15, 1 located at the same voltage location.
This is a connection line that connects the two terminals 6 and 6 so that they are electrically at the same potential.

実質的に０となる。 According to the above configuration, most of the insulating tube 4 through which the coolant 6 passes is housed in the container 13 filled with the insulating gas 20, so the room where the object to be cooled 1 is installed is humid. Even under such conditions, water droplets and dust will not adhere to the outer surface of the tube 4. Therefore, creeping discharge due to contamination and moisture on the outer surface of the tube 4 and a difference in partial voltage between the inner and outer surfaces of the tube 4 due to this do not occur, and an abnormal voltage is not applied in the thickness direction of the tube 4. Furthermore, tube 4
Both end portions 4a and 4b penetrate metal lids 15 and 16 of the container 13, respectively, but the fittings 21 and 21 and the lids 15 and 16, which are on the same potential side, are electrically at the same potential, respectively. Connecting line 2 so that
Since it is connected with tube 4, lid 1 of tube 4
The potential difference between the inner and outer surfaces of the tube 4 at the insertion portions 5 and 16 and the portion exposed to the outside of the container 13 is extremely small, and the voltage applied in the thickness direction of the tube 4 is substantially zero.

The end 4a of the tube 4 is inserted into one end of the joint fitting 21 on the low voltage side, and is tightened with the connector 25, and the liquid pipe 22 is connected to the other end.
is inserted and similarly tightened by connector 25. The other end of the liquid pipe 22 is connected to the connection fitting 2
6, connected via terminal 27 to a source of cooling liquid. The joint fitting 21 is electrically connected to the lower lid 16 at ground potential via a connecting wire 24, an ammeter 28, and a resistor 29 connected in parallel,
This makes it possible to measure leakage current. Note that the resistance value of the resistor 29 is preferably set to about 10 to 20 times that of the current meter 28, taking into account the disconnection of the ammeter 28. Also, 30 is the 0 ring.

てもよいのは勿論である。 Even with the above configuration, the potential difference between the X point inside the tube 4 and the X point on the lower lid 16 can be made extremely small, but as shown in FIG.
The insert fitting 31 is inserted into the tube 4 and is electrically connected to the joint fitting 21, so that the potential difference between the inner and outer surfaces of the tube 4 in this area is eliminated so that no voltage is applied in the thickness direction of the tube 4. Of course, it is also good.
なお、図示は省略するが、上側のフタ１５にお
いても同様の構成にすることは勿論である。 Although not shown in the drawings, it goes without saying that the upper lid 15 also has a similar configuration.
