Problems solved by technology

[0008] If the altitude angle and azimuth angle are divided according to the angular intervals that meet the requirements, the ice layer needs to be divided into thousands of small pieces, which will bring great difficulties in simulation modeling and consume a lot of time
From a simulation efficiency point of view, this approach is highly undesirable

Embodiment Construction

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0042] In this embodiment, TracePro software is selected as the optical tracing tool. Considering that its built-in modeling function is relatively simple, it is not very convenient for the construction of relatively complex structures. Therefore, firstly, the structural model of the sample chamber is established by using the Solidworks modeling software, such as figure 1 As shown, a simulation model based on a ring light source irradiating microsphere samples is then imported into TracePro to set the material properties and light source properties.

[0043] In the simulation model, set the outer radius and thickness of the spherical shell of the microsphere sample as 1000 μm and 150 μm, and the...

Abstract

The invention discloses a hydrogen isotope solid light field reconstruction method based on a ray tracing simulation model, and the method comprises the following steps: (1) establishing a sample room simulation model by utilizing modeling software, then importing ray tracing software, setting material characteristics and light source characteristics, and carrying out ray tracing; (2) carrying out regional division on a hydrogen isotope ice layer of the microsphere sample according to elevation angles; (3) obtaining an incident ray table of the ice layer of the microsphere sample on ray tracing software, and calculating the body heating rate distribution of each sub-region of the ice layer of the microsphere sample according to a hydrogen isotope solid light field reconstruction algorithm. By means of the method, high-efficiency and high-precision body heating rate distribution calculation of the hydrogen isotope solid ice layer in the microsphere sample can be achieved.

Description

technical field [0001] The invention belongs to the technical field of simulation calculation of laser energy absorption in the interaction between laser light and low-temperature hydrogen isotope solids in a sample chamber, and in particular relates to a hydrogen isotope solid light field reconstruction method based on a ray tracing simulation model. Background technique [0002] Hydrogen isotopes (deuterium, tritium, etc.) are widely used in industries, materials, detection, energy and other fields. First of all, hydrogen isotope is a safe, clean and resource-rich new energy source. Hydrogen isotopes have the following advantages: [0003] a) Abundant storage capacity. According to statistics, the deuterium content in seawater is about 0.03g / L, so there are 45 trillion tons of deuterium in the ocean alone. [0004] b) The released energy is large. If the deuterium in 1L of seawater is extracted for fusion reaction, it can provide about the energy that can be released b...
