D-D reaction cross-section

In summary, Professor Ragheb has a plot and some data in the following (see Figure 2):http://mragheb.com/NPRE%20402%20ME%20405%20Nuclear%20Power%20Engineering/Fusion%20Concepts.pdfHowever, for commercial power purposes, it would not make sense to 'heat' deuterons to 10 MeV when the yield is 4.03 MeV for the T,p production, or less, 3.27 MeV for He-3,n production.

Hi,

I have been searching d-d reaction cross-section at higher energies up to 10 MeV. I checked ENDF database, however, I could not find any data. Do anyone offer a source from which I can get d-d cross-section data?

thanks in advance.

I believe it has been published, e.g., Thomas J Dolan's text, Fusion Research, Volume I: Principles

Thank you for the source. I am not going to use this data for power related purpose, rather I am going to need it for neutron yield calculation. By the way, you mentioned the yield. Did you mean the net energy yield?

The ENDF is a very complete library, but in the future try using this part of their site for more detailed information than what you find on the main landing page:

I just realized I posted the wrong data set (must have been spending too much time on their site that day), this is what you are looking for if interested in the D+D->t+p cross section:

and this one for the D+D->He3+n cross sections:

Try the site out for yourself, it is very useful and full of information when it is working properly.

1. What is a D-D reaction cross-section?

A D-D reaction cross-section is a measure of the probability of two deuterium atoms undergoing a nuclear reaction and producing a specific result. It is typically represented by the symbol σ and is often used in the study of nuclear fusion.

2. How is the D-D reaction cross-section calculated?

The D-D reaction cross-section is calculated by taking into account the energy of the deuterium atoms, the distance between them, and the characteristics of the reaction itself. This calculation can be complex and often requires advanced mathematical models and computer simulations.

3. What factors affect the D-D reaction cross-section?

Several factors can affect the D-D reaction cross-section, including the energy of the deuterium atoms, the presence of other particles or fields, and the temperature and density of the environment in which the reaction takes place. Changes in these factors can result in changes in the probability of a D-D reaction occurring.

4. Why is the D-D reaction cross-section important?

The D-D reaction cross-section is important because it helps scientists understand and predict the behavior of nuclear reactions. By studying the cross-section, scientists can determine the likelihood of a specific reaction occurring and make more accurate predictions about the outcome of nuclear fusion experiments.

5. How is the D-D reaction cross-section used in research?

The D-D reaction cross-section is used extensively in research related to nuclear fusion and other nuclear reactions. It is also used in the development and design of fusion reactors and other technologies that utilize nuclear reactions. Additionally, the D-D reaction cross-section is used in theoretical studies and simulations to better understand the behavior and potential applications of nuclear fusion.
