Description
Technical field
This utility model relates to the Elevated temperature irradiation target chamber of a kind of temperature-controllable, and the multi beam of a kind of temperature-controllable is simultaneously
The high-temperature target chamber of irradiation, this high-temperature target chamber is mainly used in the HIB under hot conditions, H rays, helium ion beam simultaneously
The experiment of exposed material.
Background technology
In reactor, the topmost failure mode of heap inner structure material is irradiation damage, and the structure thus caused
The decline of the combination property of material.Irradiation damage can affect the service life of heap inner structure material, and the safety of initiation reaction heap
Problem, the problem that therefore it must take into and study in being reactor structural material research and development.
Heap inner structure material is subject primarily to the irradiation carrying moderate energy neutron and transmuting charged particle etc. of high dose.Transmuting band electrochondria
Son is the product of the transmuting reaction of reactor, mainly hydrogen and helium.Therefore, material is not only subject to the neutron irradiation of very high dose,
But also with by hydrogen, the synergism of helium.Neutron and heavy ion are all the displacements of the atom being produced material by collision,
Therefore, it is possible to use heavy ion irradiation simulates neutron irradiation.Heavy ion, hydrogen, helium three beams irradiation test simultaneously is generally used
The irradiation damage of research reactor inner structure material.
But, the temperature of existing three beams irradiation devices is the highest.It is currently used for the target chamber temperature one of heavy ion irradiation
As can only achieve six or seven hundred degree, this type of target chamber be generally used for secondary reactor structural material irradiation damage research.More of new generation
