受控热核聚变和等离子体物理研究装置中的真空测量是一种特殊环境下的真空测量.简要介绍了真空测量在等离子体容器中的应用和意义.对这种特殊环境进行了描述.并对如何解决这些复杂环境中正确可靠地测量压力(密度)提出了意见.等离子体物理研究装置中存在着很强的磁场和各种带电粒子、快速中性粒子、中子,高能光子等的强烈干扰.要正确、可靠地测量容器中的压力(密度).必须研究抗干扰测量技术.此外、装置中气体状态处于非平衡气流条件下.被测的气体分子既是空间位置的函数.也是空间方位的函数.容器中气流瞬变.要求测量必须快速.介绍了已研制成功的快速抗干扰真空规.这种规采用了几何屏蔽和脉冲调制抗干扰技术并利用了环境中的磁场强度.进一步提高了抗干扰能力.这种规还在入口采用威尼斯平行叶片百叶窗的结构和纵横交叉的电场屏蔽,保证了入口的气体流导,既解决了快速测量问题,又解决了抗干扰的要求.
Vacuum measurement in a controlled thermonuclear fusion and plasma physics research facility is a vacuum measurement in a special environment. The application and significance of vacuum measurement in a plasma vessel are briefly described. This particular environment is described. Some suggestions are put forward on how to deal with the correct and reliable measurement of pressure (density) in these complex environments.Plasma physics research device has a strong magnetic field and strong charged particles, fast neutrons, neutrons and high-energy photons Interference. To measure the pressure (density) in the container correctly and reliably, anti-jamming techniques must be studied. In addition, the gas state in the device is under non-equilibrium flow conditions. The molecules of the gas being measured are both a function of the spatial position and also of the spatial orientation The function of the flow transient in the container. The measurement must be fast. The rapid anti-jamming vacuum gauge that has been developed is introduced. This gauge uses geometrical shielding and pulse-modulated anti-jamming technology and utilizes the magnetic field strength in the environment. The anti-jamming capability of this regulation is also used in the entrance of the Venetian parallel leaf shutter structure and vertical and horizontal electric field shielding, Permit gas flow conductance entrance, which addresses the problem of rapid measurement, but also solve the requirements of anti-interference.
