Abstract

This invention discloses a window neck tube structure of a special superconductive Tokamak nuclear fusion device vacuum chamber, including a shell of the vacuum chamber, in which, the chamber includes a level window and a vertical window installed with neck tubes on them characterizing that said neck tubes have two sections of ripple tubes and a hard tube between the two sections of ripple tubes, thus the chamber can absorb heat distortion effectively and the neck tube keeps linearity along the axial direction so as to guarantee the normal work of some diagnosis devices.

Description

technical field

[0001] The invention belongs to a component of a superconducting tokamak nuclear fusion device, in particular to a neck tube structure of a special horizontal window and a vertical window of the superconducting tokamak nuclear fusion device. Background technique

[0002] The superconducting tokamak device vacuum chamber is an ultra-high vacuum container with complicated structural design and processing technology among similar devices. It is one of the "heart" components of the device host and the direct place for plasma operation. Physics, plasma physics, mechanics, vacuum and mechanics and other disciplines, according to the requirements of physical experiments, there are many horizontal and vertical windows on the vacuum chamber body, which are used for diagnosis, heating, pumping, gas charging, cooling, etc. A common feature is that the end face of the window flange is far away from the center of the device, and the operating temperature of the vacuum cha...
