A good question. I think what we would aim to help lend a little credibility (as it seems publishing peer-reviewed research is not enough) and increase exposure to the public. It would be great if it was done as part of a crowdfunding campaign to raise investment, but considering the current round is closing soon, that would not be an option for now.
MIT SPARC approach we did cover, it is certainly an interesting venue to be investigated, even if it fails to live up to the hype

there has been some discussion in reddit about it
A somewhat critical look at the MIT announcement

However Saphire is a different matter as I consider it non-scientific due to lack of scientific publications, evidence of fusion reactions and (pseudo)religious claims. While I would love to have more and active discussion, due to this reason this thread goes to the ZPM section.
Cross section is more probabilistic due to particle-wave duality, but basically yes, the bigger the cross-section the more likely a fusion reaction will occur considering there is enough energy to overcome the coulomb barrier.
The X ray (bremsstrahlung) suppression is due to ultra-high magnetic field that Eric theorized occurs during the pinch. Because with a stronger magnetic field, electrons as charged particles will have to closely orbit the magnetic field lines and wont be able to hit atoms nucleus (I think) so much, and reducing collisions will reduce the amount of X-rays. This was widely theorized, but not sure sure how much it was tested due to difficulty of achieving these level of magnetic fields:

Also beryllium electrode is X-ray transparent so it will reduce the corrosion due to X-ray heating and thermal evaporation.
AFAIK is exactly what LPP plans to do to increase density after impurities are eliminated. They could not do it before because higher current would mean greater erosion of electrodes and therefore more contamination. With beryllium electrode impurities will not matter so much and hopefully any mechanical stress will not be too severe to damage the electrodes
Here is an update from pineapple fund:

They received thousands of applications and are processing them. Hopefully ours gets trough, but again it is a long shot as it not very easy to explain how important fusion is in a paragraph or two.
The banner has been removed. Hopefully it served its purpose, otherwise court will surely follow.
Moved to separate topic as it seems unrelated
So basically they are feeding a ton on energy into it, and this allows it to stay “stable”. Interesting, not sure if there are applications, but would be amazing if it was feasible to burn plasma in open air.
Interesting, the timeline of one picosecond is a bit short and they probably cant be magnetically contained in the pinch, but if something can fuse bottom quarks en masse I would bet on a DPF.
Updated php version so statistics start working now (found in right hand Daashboard->Statistics), for now will only provide access to some people.
Thanks Francis, good to know for general background, but due to intense focii points PIC simulations probably won’t be suitable as they use a fixed mesh
Is there a reason why you would not want people to be able to use the same login for both blog comments and forum comments as that would make it quite tedious and probably prevent a lot of the activity?
I have added a feature request for the comment section and will work on finding a web developer to help me out implement necessary features
I actually added it a bit ago, so let maybe think about other desired features. I think it would be good for people to specialise as at least for me its a bit too much responsibility at the moment. As a side note you can see from the attachment that your work is very valuable too and I am sure you can find more ways to contribute from the main strengths such as marketing.
