その作業が面倒である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slit exchange device for a beam duct in a cyclotron. In the beam duct of a cyclotron, it may be necessary to forcibly limit the beam size. Conventionally, the operation of the cyclotron has been stopped, the slit device has been disassembled, and the slit has been replaced, but this process is cumbersome.

６を連結する。 As shown in the first figure, beam ducts 4 and 5 having a square cross section are connected to the outlet 3 of the beam 2 of the small cyclotron 1 with their oblique sides perpendicular, and a target box 6 is connected to the end of the beam duct 5. Concatenate.
なお図中７は厚さ１ｍ程度の鉛よりなる放射線
防護壁、８はビーム遮断弁である。 In the figure, 7 is a radiation protection wall made of lead with a thickness of about 1 m, and 8 is a beam cutoff valve.

の長さ即ち余裕幅l1より小さくする。 A slit exchange device 10 is provided in the middle of the beam duct 5. As shown in the second and third figures, in the case 11 of this slit exchange device 10, the slider 1 is
2 is inserted into the beam duct 5 so as to swing in a direction perpendicular to the central axis, and the slider 12 has two through holes 1.
3 and 14, and several types of slits S are removably attached to one of the through holes 13. These through holes 13,
There are airtight seals 15, 16, 17 on both sides of 14.
18, and the distance l between the adjacent seals 16 and 17 is made smaller than the length from the end of the housing 11 to the edge of the beam duct 5, that is, the margin width l1 .
次にこの装置の動作を説明する。 Next, the operation of this device will be explained.
第２，３図示の状態では透孔１３がビームダク
ト５に連通する位置にあり、ビーム２はその透孔
１３を通つてターゲツトボツクス６に到る。 In the state shown in the second and third figures, the through hole 13 is in a position communicating with the beam duct 5, and the beam 2 passes through the through hole 13 and reaches the target box 6.

は所定の真空に保持される。 When you want to narrow down the size of the beam 2 with a slit, move the slider 12 upward (3rd
(to the right in the figure). At this time, the seal 17 first enters the housing 11, then the seal 16 comes off from the beam duct 5, and before the seal 16 escapes from the housing 11, the seals 17 and 18 connect to the communication hole with the beam duct 5. to seal. Thus, the slit S and the through hole 14 come to a position where they communicate with the beam duct 5, and the beam 2 is narrowed down. At this time, the air in the slit S and its through hole 14 enters the beam duct 5, but since the inside of the beam duct 5 is constantly sucked by the vacuum pump, the inside of the beam duct 5 is immediately maintained at a predetermined vacuum.
ビーム２を絞る量を変えたいときにはスライダ
１２を逆方向に摺動させて第２，３図示のように
スリツトＳと透孔１４を引きだし、別の大きさの
スリツトＳに交換して再びスライダ１２を摺動さ
せればよい。 If you want to change the amount by which the beam 2 is narrowed, slide the slider 12 in the opposite direction, pull out the slit S and the through hole 14 as shown in the second and third figures, replace it with a slit S of a different size, and then move the slider 12 again. All you have to do is slide it.
以上のように本考案によれば、ビームダクト中
の真空を大幅に破ることなく、スリツトを任意の
大きさのものと変えることができ実用上便利であ
る。 As described above, according to the present invention, the slit can be changed to any size without significantly breaking the vacuum in the beam duct, which is convenient in practice.
