Thanks for your kind words, greatly appreciated!
Concerning your request: I have actually done that in a lecture I gave 2 month ago and I wanted to add that to the plot-script here. I will have a close look at your code and compare it with my code over the next days (somewhat busy these days, sorry) and then come back to you here - I'm curious to see if there are any difference :)
Well, I've just realized that I have already added that to the fusion_reactivity plot :)
Is that what you were looking for?
hi @alfkoehn thanks for reaching out!
This is indeed what I was looking for 😄 I had similar results for pp cross sections (waaayy lower than DD, DT...). Shall I start a PR to add this to fusion_cross_sections.py ?
hi @RemDelaporteMathurin, sorry for my extremely late answer! Isn't this what you are looking for: https://github.com/alfkoehn/fusion_plots/tree/master/fusion_reactivity , i.e. in my understanding your suggestion is already part of the package?
hi @alfkoehn , no probs
You are right it is included in fusion_reactiviy, but not in cross sections (which are a bit different). I know that the pp cross section would be way lower, but maybe users could have the possibility to add it.
It's a nice comparison sometimes required to show why we cannot simply burn H-H plasmas
Ah, you're right of course. I'm just wondering now why I haven't included them... will look into it and comment here as soon as I have added them.
I'm just wondering now why I haven't included them..
One reason might be that the pp cross section is so low, it would squish all the curves and we wouldn't see anything. But that's the point in a way. I find it useful to say: "this is the cross sections of DD DT etc. Why don't we use HH? well here it is, down below"
I was also looking for the pp cross section, but according to:
Adelberger, E.G., et al.., 1998. Solar fusion cross sections. Rev. Mod. Phys. 70, 1265–1291. https://doi.org/10/ftx3j3
However, the rate for the fundamental p + p -> 2D + e+ + nu_e reaction is too small to be measured in the laboratory. Instead, the cross section for the p-p reaction must be calculated from standard weak-interaction theory.
And indeed I didn't manage to find experimental values for p-p in any paper. I didn't try to make it from the analytical expression presented in the paper.
Hi! thanks for that great package. Very useful!
I'd like to plot cross sections with the pp reaction. Do you think there's a way of adding this to fusion_cross_sections.py ?
I've come up with that script so far but must've messed up something with the units...
