Description
Technical field
The invention belongs to the target technology field in inertial confinement fusion (ICF), be specifically related to a kind of filling aeroge ICF cold
Freeze target system.
Background technology
Inertial confinement fusion (ICF), is the technology of a kind of nuclear fusion, utilizes the shock wave of laser to carry out initiated core fusion anti-
Should, it is one of main method realizing great change igniting.
In inertial confinement fusion, ignition condition requires high temperature, high density and certain yardstick, uses Laser Driven also to need
Wanting supercharging means, its substantially process is: laser the most uniformly heats Spherical pellet surface, forms one on target surface
Floor height temperature dilute plasma, when then laser is by this layer of dilute plasma, anti-with inverse tough some plasma of making peace
Often absorption process is absorbed.Absorbed laser energy adds rapidly thermoelectron, and temperature can reach 35 thousand ten thousand degree.High-temperature electronic leads to
Cross Electron Heat Conduction, again by region high for major part energy transport to the ablation layer density closing on uptake zone, form a high temperature
Ablation front (interface, a temperature space jumpy), and high ablation pressure is produced at this, this is a pressurization.It
Laser radiation force is improved nearly thousand times.Ablation pressure drives the material near ablation front, on the one hand by a part of high-temperature high-density etc.
Gas ions material sprays outward towards low-density plasma slab, on the other hand due to the relation of action and counteraction, and will residue
Solidifiable substance compression and to center accelerated motion, produce poly-heart shock wave, compress deuterium tritium fuel, here it is the containing of inertial confinement
Justice.This process is known as " implosion ", by spherical implosion and the poly-heart effect of implosion process, makes the pressure of deuterium tritium fuel increase again
Add several ten thousand times, when reaching igniting, require the fuel pressure reached.
Present stage, ICF was the most commercial, and still in conceptual phase, the raising to its ignition effectiveness still awaits research, igniting
Success or not and efficiency are closely related with the combination property of cryogenic target.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide a kind of filling aeroge ICF freezing
Target system, effectively improves the even property of temperature distributing disproportionation, and suppression laser irradiates the Au plasmas that black cavity wall produces, improves cold
Freeze pellet implosion performance.
In order to achieve the above object, the technical scheme that the present invention takes is:
