중이온 가속기의 HWR 저온유지장치HWR cryostat of heavy ion accelerator

가속기는 양성자와 우라늄 빔을 가속시키는 장치의 일종이다. 즉 가속기는 전자, 양자 및 이온 등의 하전입자를 고에너지 상태(예를 들면, 수백만 전자볼트에서 수조 전자볼트 정도의 고에너지 상태)로 가속하는 장치로, 가속원리에 따라 고주파 가속기와 양자용 유도 가속 싱크로트론으로 크게 구별할 수 있다.An accelerator is a type of device that accelerates protons and uranium beams. In other words, the accelerator is a device that accelerates charged particles such as electrons, protons, and ions into a high energy state (for example, a high energy state of several million electron volts to several trillion electron volts). Accelerated synchrotrons can be largely distinguished.

In addition, the size of the high frequency accelerator varies according to the use, and there are high frequency accelerators for obtaining large energy, ranging from large accelerators for atomic nucleus and small particle physics research to small size high frequency synchrotrons for cancer treatment that supply ion beams at relatively low energy levels.

즉, 저온유지장치는 복수의 중이온 가속관(100)을 포함하며, 각각의 중이온 가속관(100)에 액체 헬륨(He)을 공급받아 중이온 가속관(100)의 성능을 테스트하기 위한 것이다.That is, the cryostat includes a plurality of heavy ion accelerator tubes 100 and is configured to test the performance of the heavy ion accelerator tube 100 by receiving liquid helium (He) in each of the heavy ion accelerator tubes 100.
도 2를 참고하면, 진공 모듈(200) 내에 2개의 중이온 가속관(100)이 소정 간격을 두고 서로 이격된 상태로 수직 배치되어 있다.Referring to FIG. 2, two heavy ion accelerator tubes 100 are vertically spaced apart from each other at predetermined intervals in the vacuum module 200.
각각의 중이온 가속관(100)은 대략 원통형으로 이루어지며, 파이프 모듈(300)로부터 액체 헬륨을 공급받아 중이온 가속관(100)으로서의 성능 테스트를 한다.Each heavy ion accelerator tube 100 has a substantially cylindrical shape, and receives liquid helium from the pipe module 300 to perform a performance test as the heavy ion accelerator tube 100.
중이온 가속관(100)은 도시하지 않았으나 내부관과 외부관의 2중관으로 이루어진다. 내부관 내에는 중이온 가속관(100)의 효율적인 빔 가속을 위해 진공 상태를 유지하고, 외부관과 내부관 사이에는 중이온 가속관(100)의 저온 유지를 위한 액체 헬륨이 주입된다. 따라서, 내부관에는 후술하는 진공펌프의 진공라인(도시 생략)이 연결되고, 외부관과 내부관 사이의 상단부 및 하단부에는 파이프 모듈의 파이프 라인(112)이 각각 기계적으로 연결되어 헬륨을 공급받거나 배출하게 된다.Heavy ion accelerator tube 100 is not shown but consists of a double tube of inner tube and outer tube. The inner tube maintains a vacuum state for efficient beam acceleration of the heavy ion accelerator tube 100, and liquid helium is injected between the outer tube and the inner tube to maintain the low temperature of the heavy ion accelerator tube 100. Therefore, a vacuum line (not shown) of a vacuum pump to be described later is connected to the inner tube, and the pipe line 112 of the pipe module is mechanically connected to the upper end and the lower end between the outer tube and the inner tube, respectively, to receive or discharge helium. Done.
중이온 가속관(100)의 내부에는 중이온 빔의 가속을 위한 통로 역할을 하도록 빔 파이프(110)가 관통 설치될 수 있다.The beam pipe 110 may be penetrated inside the heavy ion accelerator tube 100 to serve as a passage for accelerating the heavy ion beam.
도 2 및 도 3을 참고하면, 진공 모듈(200)은 빔 가속을 위해 진공 상태를 형성해 주는 것으로, 진공 챔버(210), 진공 펌프(220)를 포함한다.2 and 3, the vacuum module 200 forms a vacuum state for beam acceleration, and includes a vacuum chamber 210 and a vacuum pump 220.
진공 챔버(210)는 중이온 가속관(100) 및 그 중이온 가속관(100)에 연결된 파이프 모듈(300)을 내부에 안치하여 외부의 환경으로부터 보호하는 역할을 한다. 진공 챔버(210)의 일측면(본 실시예에서는 바닥면)에는 진공 펌프(220)와 연결되도록 진공 포트가 적어도 하나 이상 형성된다. 진공 챔버(210)는 강도 및 내부식성이 우수한 스테인리스 스틸(예를 들면, STS316L)로 제작될 수 있다.The vacuum chamber 210 serves to protect the heavy ion accelerator tube 100 and the pipe module 300 connected to the heavy ion accelerator tube 100 from inside to protect it from the external environment. At least one vacuum port is formed on one side (bottom surface in this embodiment) of the vacuum chamber 210 to be connected to the vacuum pump 220. The vacuum chamber 210 may be made of stainless steel (for example, STS316L) having excellent strength and corrosion resistance.
본 발명의 실시예에서 진공 챔버(210)는 대략 육면체로 형성되어 있으나, 이는 중이온 가속관(100)의 수납 용이성과 기타 모듈과의 연계를 위한 설계일 뿐 그 형태에 한정될 필요는 없다. 진공 챔버(210)의 일측면에는 액체 헬륨을 제공받는 헬륨 포트(211) 및 가속된 빔을 조사하는 빔 포트(212)가 구비되어 있다.In the embodiment of the present invention, the vacuum chamber 210 is formed in a substantially hexahedron, but this is not only limited to the shape of the design for the ease of storage of the heavy ion accelerator tube 100 and other modules. One side of the vacuum chamber 210 is provided with a helium port 211 provided with liquid helium and a beam port 212 for irradiating the accelerated beam.
진공 펌프(220)는 진공 챔버(210)의 일측에 배치되어 진공라인을 통해 진공 포트와 연결되며, 중이온 가속관(100)에서의 중이온 빔의 가속을 촉진하기 위해 중이온 가속관(100)들의 내부 및 진공 챔버(210)의 내부를 진공 상태로 형성시켜 준다. 예컨대, 진공 펌프(220)는 복수 구비되어 진공 챔버(210)와 중이온 가속관(100)들에 각각 연결될 수 있다.The vacuum pump 220 is disposed on one side of the vacuum chamber 210 is connected to the vacuum port through the vacuum line, the inside of the heavy ion accelerator tube 100 to promote the acceleration of the heavy ion beam in the heavy ion accelerator tube 100 And the inside of the vacuum chamber 210 is formed in a vacuum state. For example, a plurality of vacuum pumps 220 may be provided and connected to the vacuum chamber 210 and the heavy ion accelerator tubes 100, respectively.
도 2 및 도 6을 참고하면, 파이프 모듈(112)은 중이온 가속관(100)에 성능 테스트용 유체, 예컨대 액체 헬륨(He)을 공급하는 것으로, 파이프 라인(310), 리저버(320)(330)를 포함할 수 있다.2 and 6, the pipe module 112 supplies a performance test fluid, such as liquid helium (He), to the heavy ion accelerator tube 100, and includes a pipeline 310 and a reservoir 320 and a 330. ) May be included.
파이프 라인(310)은 헬륨 탱크(도시 생략)와 중이온 가속관을 연결해 주며, 헬륨 탱크로부터 액체 헬륨을 중이온 가속관으로 공급해 주거나, 공정 진행시 발생하는 열에 의해 중이온 가속관 내에 기화된 헬륨을 헬륨 탱크 측으로 회귀하는 역할을 한다.The pipeline 310 connects the helium tank (not shown) with the heavy ion accelerator tube, and supplies liquid helium from the helium tank to the heavy ion accelerator tube, or helium tank vaporized in the heavy ion accelerator tube by the heat generated during the process It serves to return to the side.
리저버(320)(330)는 파이프 라인(310)의 일단에 장착되어 보조 헬륨 탱크의 역할을 한다. 예컨대, 중이온 가속관으로 공급되거나 또는 중이온 가속관으로부터 배출되는 헬륨이 설정치에 미치지 못할 경우 소정량의 헬륨을 저장하고 있는 리저버에서 그만큼의 헬륨을 보충하여 공급하거나 배출하는 역할을 한다.The reservoirs 320 and 330 are mounted at one end of the pipeline 310 to serve as an auxiliary helium tank. For example, when helium supplied to the heavy ion accelerator tube or discharged from the heavy ion accelerator tube does not reach the set value, the reservoir storing a predetermined amount of helium supplements and supplies or discharges the helium in the reservoir.
이때, 리저버는 메인 리저버(320)와 서브 리저버(330)로 구분될 수 있다. 메인 리저버(320)는 공정 진행시 요구되는 설정 온도의 헬륨을 저장하게 되고, 서브 리저버(330)는 설정 온도에서 벗어나는 헬륨을 저장하게 된다. 따라서, 메인 리저버(320)와 서브 리저버(330) 사이에는 헬륨의 온도를 설정 온도에 맞게 열교환시켜 줄 수 있는 열교환기(340)가 개재될 필요가 있다.At this time, the reservoir may be divided into a main reservoir 320 and a sub reservoir 330. The main reservoir 320 stores helium at the set temperature required for the process, and the sub reservoir 330 stores helium that is out of the set temperature. Therefore, a heat exchanger 340 may be interposed between the main reservoir 320 and the sub reservoir 330 to heat exchange the helium temperature according to the set temperature.
도 7을 참고하면, 메인 리저버(320)는 양단이 폐쇄된 대략 원통형으로 이루어진 리저버 몸체(321)를 포함하며, 리저버 몸체(321)에는 헬륨 탱크로부터 헬륨 액체를 공급받는 인렛포트(322) 및 기화된 헬륨을 헬륨 탱크 측으로 배출하는 아웃렛포트(323)가 서로 소정의 간격으로 이격되어 형성된다.Referring to FIG. 7, the main reservoir 320 includes a reservoir body 321 having a substantially cylindrical shape with both ends closed, and the reservoir body 321 has an inlet port 322 and vaporization supplied with helium liquid from a helium tank. Outlet ports 323 for discharging the helium to the helium tank side are formed spaced apart from each other at a predetermined interval.
또한 리저버 몸체(321) 내에는 쿨링 다운(cooling down)시 기화된 헬륨을 배출하고 유입된 액체헬륨을 일정한 양으로 유지하도록 하기 위한 목적으로 인렛포트와 아웃렛포트의 경계 부분에 복수의 배플(baffle)(324)이 형성될 수 있다. 복수의 배플 중 어느 하나의 배플(324)의 일측에는 리저버 몸체(321) 내를 통과하는 헬륨의 양을 검지하기 위한 레벨 게이지가 설치될 수 있다. 배플(324)은 리저버 몸체(321) 내를 완전히 폐쇄하도록 형성되지 않고 일부분이 연통되도록 리저버 몸체(321)의 내경보다 조금 작은 직경을 갖도록 형성된다.In addition, the reservoir body 321 has a plurality of baffles at the boundary between the inlet port and the outlet port for the purpose of discharging the helium vaporized during cooling down and maintaining the liquid helium flowing in a constant amount. 324 may be formed. One side of the baffle 324 of the plurality of baffles may be provided with a level gauge for detecting the amount of helium passing through the reservoir body 321. The baffle 324 is not formed to completely close the inside of the reservoir body 321, and is formed to have a diameter that is slightly smaller than the inner diameter of the reservoir body 321 so that a portion thereof communicates with the baffle 324.
서브 리저버 역시 메인 리저버의 구성과 대동소이하므로, 자세한 설명은 생략한다.Since the sub reservoir is also similar to the configuration of the main reservoir, detailed description thereof will be omitted.
도 2 및 도 8을 참고하면, 서포트 모듈(400)은 중이온 가속관(100)에 접촉되도록 설치되며, 중이온 가속관(100)의 배치 및 고정상태를 안정화시켜 주는 것으로, 중이온 가속관을 지지하는 서포트 몸체(410), 서포트 몸체(410)를 지지하는 서포트 바(420)를 포함할 수 있다.2 and 8, the support module 400 is installed to contact the heavy ion accelerator tube 100, and stabilizes the arrangement and fixation of the heavy ion accelerator tube 100 to support the heavy ion accelerator tube. The support body 410 may include a support bar 420 supporting the support body 410.
서포트 몸체(410)는 중이온 가속관을 둘러싸도록 대략 사각 틀체 형상으로 이루어진다. 또한, 서포트 몸체는 복수의 중이온 가속관이 각각 삽입되도록 중이온 가속관의 숫자와 대응되는 숫자로 구획된다.The support body 410 has a substantially rectangular frame shape to surround the heavy ion accelerator tube. In addition, the support body is partitioned into a number corresponding to the number of heavy ion accelerator tubes so that a plurality of heavy ion accelerator tubes are respectively inserted.
서포트 바(420)는 복수 구비되며, 각각의 일단은 서포트 몸체의 여러 개소에 연결되고 타단은 진공 챔버(210)의 여러 개소에 연결되어 서포트 몸체(410)를 고정시켜 줌으로써, 서포트 몸체(410) 내에 놓인 중이온 가속관을 안정적으로 고정시켜 준다. Support bar 420 is provided with a plurality, each end is connected to several places of the support body and the other end is connected to several places of the vacuum chamber 210 to secure the support body 410, the support body 410 It stably fixes the heavy ion accelerator tube inside.
진공 챔버(210) 내는 극저온을 형성하기 때문에 진공 챔버(210) 내에서 서포트 바에 응축이 발생할 경우 중이온 가속관의 정렬 상태가 설정 위치에서 벗어날 수 있고 이로 인해 빔 포트의 위치가 어긋날 수 있으므로, 서포트 바(420)는 저온에서 응축이 최소화되는 재질로 이루어지는 것이 바람직하다. 예컨대 서포트 바는 G10 또는 인바의 재질로 형성될 수 있다.Since the vacuum chamber 210 forms a cryogenic temperature, when the support bar is condensed in the vacuum chamber 210, the alignment state of the heavy ion accelerator tube may deviate from the set position, and thus the position of the beam port may be shifted. 420 is preferably made of a material that minimizes condensation at low temperatures. For example, the support bar may be formed of a material of G10 or Invar.
서포트 바(420)는 진공 챔버(210) 외부의 상온에서 기본적으로 길이 조정이 된 상태로 진공 챔버(210) 내로 유입되는데, 진공 챔버(210) 내부는 극저온을 유지하므로 소정의 응축이 발생할 수 있다. 따라서, 진공 챔버(210) 내에 배치된 상태에서도 서포트 바(420)의 길이 조절이 가능하도록 각 서포트 바의 일단에는 길이조절부재(430)가 장착될 수 있다.The support bar 420 is introduced into the vacuum chamber 210 in a state where the length is basically adjusted at room temperature outside the vacuum chamber 210. Since the inside of the vacuum chamber 210 maintains a cryogenic temperature, a predetermined condensation may occur. . Therefore, the length adjusting member 430 may be mounted at one end of each support bar so that the length of the support bar 420 can be adjusted even in the vacuum chamber 210.
이러한 서포트 모듈(400)에 의해 중이온 가속관(100)은 각각 개별적으로 분해 조립이 용이하며, 따라서 성능 시험이 안정적, 효율적으로 진행될 수 있다.By the support module 400, the heavy ion accelerator tube 100 can be easily disassembled and assembled individually, so that the performance test can be performed stably and efficiently.
도 2 및 도 4를 참고하면, 본 발명의 저온유지장치는, 진공 챔버(210)의 내부에 진공 챔버(210) 외부로부터 진공 챔버(210) 내부의 중이온 가속관(100)에 가해지는 외부 전자파를 차단하기 위한 마그네틱 쉴드(magnetic shield)(500)를 더 포함할 수 있다.2 and 4, in the cryostat of the present invention, external electromagnetic waves applied to the heavy ion accelerator tube 100 inside the vacuum chamber 210 from the outside of the vacuum chamber 210 inside the vacuum chamber 210. It may further include a magnetic shield (magnetic shield) 500 for blocking the.
외부 전자파가 중이온 가속관(100)에 전해지면 설정된 극저온 상태가 불안정할 수 있으므로, 마그네틱 쉴드(500)는 이러한 방해 요소를 제거하는 것이다. 마그네틱 쉴드(500)는 예컨대, Ni 75%, Fe 20%, Cu 5%의 합금의 뮤 메탈(Mu-matal)로 형성될 수 있다.When the external electromagnetic wave is transmitted to the heavy ion accelerator tube 100, the set cryogenic state may be unstable, and the magnetic shield 500 removes such an obstacle. The magnetic shield 500 may be formed of, for example, a mu-matal of an alloy of 75% Ni, 20% Fe, and 5% Cu.
마그네틱 쉴드(500)는 진공 챔버(210)의 내벽에 장착되므로, 진공 챔버(210)의 내부 형태와 유사하게 형성된다. 마그네틱 쉴드(500)의 일측면 상단에는 진공 챔버(210)의 헬륨 포트(211)에 대응되도록 제1 헬륨 포트 관통공(510)이 형성되고, 정면 하단에는 진공 챔버(210)의 빔 포트(212)에 대응되도록 제1 빔 포트 관통공(520)이 형성된다.Since the magnetic shield 500 is mounted on the inner wall of the vacuum chamber 210, the magnetic shield 500 is formed similarly to the internal shape of the vacuum chamber 210. A first helium port through hole 510 is formed at an upper end of one side of the magnetic shield 500 to correspond to the helium port 211 of the vacuum chamber 210, and a beam port 212 of the vacuum chamber 210 is formed at the front lower end of the magnetic shield 500. ), The first beam port through hole 520 is formed.
도 2 및 도 5를 참고하면, 본 발명의 저온유지장치는, 진공 챔버(210)의 내부, 바람직하게는 마그네틱 쉴드(500)의 내부에 설치되어, 냉매를 순환시켜 진공 챔버(210) 내부의 저온 상태를 활성화하기 위한 써멀 쉴드(600)를 더 포함할 수 있다.2 and 5, the cryostat of the present invention is installed inside the vacuum chamber 210, preferably inside the magnetic shield 500, and circulates a refrigerant to circulate inside the vacuum chamber 210. The thermal shield 600 may be further included to activate a low temperature state.
써멀 쉴드(600)는 열전도율이 높은 구리(Cu)로 제작될 수 있고, 냉매로는 기체 상태의 질소(N)가 사용될 수 있다.The thermal shield 600 may be made of copper (Cu) having high thermal conductivity, and gaseous nitrogen (N) may be used as the refrigerant.
써멀 쉴드(600) 역시 마그네틱 쉴드(500)와 마찬가지로 진공 챔버(210)의 내벽에 장착되므로 진공 챔버(210)의 내부 형태와 유사하게 형성된다. 따라서, 써멀 쉴드(600)의 일측면 상단에는 진공 챔버(210)의 헬륨 포트(211)에 대응되도록 제2 헬륨 포트 관통공(610)이 형성되고, 정면 하단에는 진공 챔버(210)의 빔 포트(212)에 대응되도록 제2 빔 포트 관통공(620)이 형성된다.Since the thermal shield 600 is mounted on the inner wall of the vacuum chamber 210 similarly to the magnetic shield 500, the thermal shield 600 is formed similarly to the internal shape of the vacuum chamber 210. Accordingly, a second helium port through hole 610 is formed at an upper end of one side of the thermal shield 600 to correspond to the helium port 211 of the vacuum chamber 210, and a beam port of the vacuum chamber 210 is formed at the lower end of the front surface. The second beam port through hole 620 is formed to correspond to 212.
