Where can I find d-d reaction cross-section data for higher energies?

Click For Summary

Discussion Overview

The discussion revolves around the search for d-d reaction cross-section data at higher energies, specifically up to 10 MeV. Participants explore various sources and references for obtaining this data, as well as its applications in neutron yield calculations.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses difficulty in finding d-d reaction cross-section data in the ENDF database and seeks alternative sources.
  • Another participant suggests that the data may be found in Thomas J Dolan's text, "Fusion Research, Volume I: Principles," and references a plot by Professor Ragheb.
  • A participant clarifies their intent to use the data for neutron yield calculations rather than for power-related purposes, questioning the meaning of "yield" mentioned earlier.
  • One participant recommends using a specific part of the ENDF site for more detailed information than what is available on the main page.
  • A later reply acknowledges posting incorrect data initially and provides links to the correct datasets for the D+D reactions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the availability of the data or its relevance for different applications, indicating multiple competing views and unresolved questions regarding the sources and interpretations of the data.

Contextual Notes

Some limitations include potential missing assumptions about the data's applicability, the dependence on specific definitions of yield, and unresolved details regarding the datasets referenced.

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

Professor Ragheb has a plot and some data in the following (see Figure 2):
http://mragheb.com/NPRE 402 ME 405 Nuclear Power Engineering/Fusion Concepts.pdf

However, 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.

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.
