benfParticipantAnother interesting hardware shot is this one from the gallery:

benfParticipantI’m not getting the Gallery images to display in Safari. I click on an image and a new window opens that is blank. They do display in Firefox.
benfParticipantA few examples of images from FF and LPP sites would be:

benfParticipantGreat idea updating Wikipedia. Any chance of placing images and animations along with it? Also an explanation of the aneutronic aspect of using pb11 for us newbies might broaden the interest. I see there’s a link to a detailed explanation of aneutronic at the end, but it might be better to also have a brief mention after the introductory sentence.
benfParticipantPeople should also know that Rezwan is the website’s webmaster. This is important to know because a while ago this site was having problems, which I communicated to her and she was very responsive in trying to figure it out, which wasn’t easy. All the way from Iran! The other side of the planet from where I sit!…The site works beautifully now and that is vital to me. I’ve been learning a lot from Focus Fusion. It is a portal to knowledge and opinion that is valuable for people across the globe to see. Her commentary as well has been interesting and illuminating. It bodes well for solving the problems going on in the world that we have someone from the Middle East participating in developing this technology that will contribute to a more secure and stable world. Thanks again Rezwan!
benfParticipant“Actually, preliminary calculations indicate the background plasma, the plasma in the whole vacuum chamber, will cool to something like 2,000 to 3,000 C between pulses. It just has to be hot enough to the boron will not precipitate out, which is a very complicated question of chemistry and dynamics. The electrodes propbaly have to be kept below 800 C to prevent rapid erosion.”
It seems some of my questions were already answered in this previous post by Eric Lerner, thanks…Alas, I’m not in physics or an engineer, but I do yearn to fix things that don’t perform quite right and will search far and wide for solutions. The physics of the bird cage formed by the momentum of plasma by a channelled magnetic field into a knot which then collapses or pinches, conjures a visual flood in my brain. In a bathtub drain or a tornado it’s the pressure difference between surrounding medium, angular momentum and the inside pressure that causes contraction into an accelerating vortex. How fast a spin you can get determines the concentration of energy. The bird cage analogy implies a fixed container whereas what we need is more motion and increased pressure gradients. The earth has magnetic field “lines” that are somewhat fixed to the poles because of the fixed rotation of the earth. But the energy accelerates at the poles and the fields get more confined, thus ions from solar storms accelerate to the poles when captured. I look for analogies like these in nature or other experiments I read about on the web, to try and grasp what’s going on with Focus Fusion. Indeed there’s a lot to learn, consider, explore. This is all very interesting and I’m glad there’s more funding coming to move things along. Can’t wait to see the results!
benfParticipantSpeaking of problems of confinement, or containment, I came across this item from MIT. They have found a method of using high frequency radio waves to “direct” plasma. They are applying it to a tokamak design, however I wonder if it could be utilized in the Focus model. I picture it acting like noise canceling headphones (this may be a stretch!). I don’t have all the details of this research. Can radio waves be tailored to de-energize electrons or x-rays and their heat transfer. Could a burst of radio waves during the pulse phase of Focus limit the radiation and help focus the fusion? Is it the X-rays that are producing all the heat out to the containment? How much degradation of the containment from heat is there, long term? Here’s the link to the artilce: http://www.physorg.com/news147528679.html
benfParticipantYes, we are still out here and yes, that is great news on the funding! Here’s some more promising news from MIT that might be useful, regarding containment of heat with radio waves….
http://www.physorg.com/news147528679.htmlbenfParticipantThe site is now performing brilliantly. .Glad you all figured it out. Now I can spread the word and pass along this helpful tool..
benfParticipantDon’t know if this would help, but I’ve also been having problems accessing the site lately. I’ve recently read a news item on DNS vulnerability that looked interesting as it highlights the extent to which the web has been taken over by hackers through this flaw. It can scramble server access.
Here’s the news page:
