Abstract

The invention relates to a shielding case, in particular to a heat radiation shielding case of a refrigeration target. Problems of failures to effectively protect a refrigeration target and maintain constant temperature and representation in the current refrigeration target shooting are solved. The shielding case comprises an inner shielding case, an outer shielding case, a low temperature screen, a heat insulation arm, a sealing rubber strip, two target aiming and representation windows. The inner shielding case is arranged in the outer shielding case. The inner shielding case and the outer shielding case form a shielding case body. The low temperature screen is arranged in the shielding case body. When the shielding case body is closed, the low temperature screen is connected with a cold guiding part of the inner shielding case. The contact face of the cold guiding part is of an annular vertical groove structure. The invention belongs to the field of inertial confinement fusion.

Description

technical field [0001] The invention relates to a shielding cover, in particular to a thermal radiation shielding cover of a frozen target, belonging to the field of inertial confinement fusion. Background technique [0002] Inertial confinement fusion is an effective way to realize controllable thermonuclear fusion, an effective way to solve the energy problems faced by human beings, and it is also the strategic commanding height of science and technology that developed countries are competing to occupy. And technology can create the extreme physical conditions required for some scientific experiments, and also has important applications in the defense science and technology industry. Compared with conventional targets, the number of neutrons produced by fusion of frozen targets has increased significantly, and it is the most promising target type to achieve fusion first. Frozen targets need to maintain ultra-low temperature below 18K to ensure that the target is in a froz...
