本発明は、素粒子を加速するために使用する素
粒子加速用空洞電極に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cavity electrode for accelerating elementary particles, which is used to accelerate elementary particles.
素粒子の解明を研究する物理学の分野におい
て、素粒子研究の一つの方法として素粒子を加速
し、電子と陽電子、あるいは電子と陽子とを衝突
させ、素粒子の存在を確認することが行なわれ
る。素粒子の加速器には種々の形式のものがある
が、その中の一つに高周波加速空洞がある。 In the field of physics, which studies the elucidation of elementary particles, one method of particle research is to accelerate elementary particles and collide them with electrons and positrons, or electrons and protons, to confirm the existence of elementary particles. It will be done. There are various types of elementary particle accelerators, one of which is a high-frequency acceleration cavity.
高周波加速空洞は、第１図に示すように加速空
洞ａの中心に多数の素粒子加速用電極ｂが一定間
隔で並ぶようにステムｃで吊り下げ、素粒子加速
用電極ｂの表面に高周波電流を流すようになつて
いる。そのため素粒子加速用電極ｂの表面には銅
メツキが施されているが、高周波電流による発熱
のため、素粒子加速用電極ｂを冷却しないと銅メ
ツキが劣化したり、素粒子加速電極ｂに寸法変化
等が生じ、素粒子加速電極ｂに要求される性能が
満足されなくなる。従つて、素粒子加速用電極ｂ
は水冷する必要がある。 As shown in Fig. 1, a high-frequency acceleration cavity is constructed by suspending a large number of elementary particle acceleration electrodes b in the center of an acceleration cavity a at regular intervals using a stem c, and applying a high-frequency current to the surface of the elementary particle acceleration electrodes b. It is becoming like this. For this reason, the surface of the particle acceleration electrode b is plated with copper, but due to the heat generated by the high frequency current, the copper plating may deteriorate if the particle acceleration electrode b is not cooled. Dimensional changes, etc. occur, and the performance required of the elementary particle accelerating electrode b is no longer satisfied. Therefore, the elementary particle acceleration electrode b
needs to be water cooled.
このため従来の素粒子加速用電極ｂにおいて
は、第２図に示すようにステムｃを冷却水入口管
ｄと、その中心に設けられた冷却水出口管ｅとで
構成し、素粒子加速用電極ｂのワツシヤーｆの内
部には、外側と内側とから交互にリブｇを設け、
冷却水入口管ｄからワツシヤーｆの内部に入つた
冷却水はワツシヤーｆ内を蛇行して通過し、冷却
水出口管ｅから排出するようにされている。 For this reason, in the conventional particle acceleration electrode b, the stem c is composed of a cooling water inlet pipe d and a cooling water outlet pipe e provided at the center, as shown in FIG. Inside the washer f of the electrode b, ribs g are provided alternately from the outside and the inside,
The cooling water that enters the washer f from the cooling water inlet pipe d passes through the washer f in a meandering manner, and is discharged from the cooling water outlet pipe e.
このような従来の素粒子加速用電極ｂにおいて
は、冷却水の水圧によつてワツシヤーｆの表面が
膨張して変形する。この変形量が0.5mm程度であ
つても素粒子加速用電極ｂの性能に悪影響を及ぼ
すため、ワツシヤーｆの板厚を厚くして変形しな
いようにすると冷却水の流路を大きくすることが
できず、また左右で不均一な温度分布となる。ま
た空気溜りが発生してその部分の冷却が十分でき
なくなり、性能に影響する欠点があつた。 In such a conventional particle acceleration electrode b, the surface of the washer f expands and deforms due to the water pressure of the cooling water. Even if this amount of deformation is about 0.5 mm, it will have a negative effect on the performance of the particle acceleration electrode b, so if the washer f is made thicker to prevent deformation, the cooling water flow path can be enlarged. Moreover, the temperature distribution becomes uneven between the left and right sides. Another drawback was that air pockets occurred, making it impossible to cool the area sufficiently, which affected performance.
