March 19, 201016 yr A great uncle of mine made his own many years ago. He managed to multiply 200 kilovolts to 800 kilovolts and and used it to bombard Lithium and Boron atoms with charged electrons and was the first to artifically split the atom. That was back in 1932. http://www.aip.org/history/lawrence/epa.htm
March 19, 201016 yr No sh&t Peter? I'm impressed. Mind you there's been some serious talent down your way: Oliphant & Bragg. Donald, That's just getting there. Sadly it'll have to wait two years before they can get to the full 14TeV 'cause they found the quench absorbing circuits in the power supplies for the dipoles are ropey. If they stick to protons they could do it but they won't be able to do it with lead ions. I see the new european spallation source is to be built in Sweded. Pity, I was hoping it would be built in Spain. That's a project I'd like to be involved in. Maybe if I...
March 19, 201016 yr Author Donald, That's just getting there. Sadly it'll have to wait two years before they can get to the full 14TeV 'cause they found the quench absorbing circuits in the power supplies for the dipoles are ropey. If they stick to protons they could do it but they won't be able to do it with lead ions. The "quench" issue is something that intrigues me. LHC are pushing the absolutes of Physics to reach the target of formally identifying Higgs boson however how many more absolutes are going to have to be established to get the conditions right to detect the particle. Are they going to have to reach supercooling levels never before achieved to keep the magnets stable? to me at this stage there are more questions than answers as to where the physics goes to reach the targets they are aiming for.
March 19, 201016 yr Superconducting (s/c) magnets aren't as cutting edge as many believe Don. Actually they're quite common in this field (ha ha..geddit?). The LHC is unusual because it uses so many of them. The s/c magnets used at CERN are low temp magnets and require liquid helium to get them to 2.8K. Liquid helium is expensive, about the same as your 10 yo finest. Nowadays high temp s/c's are the vogue (HTS-110 speciality.) and they go s/c at 70K. High enough for liquid nitrogen which is about the same cost as milk. Quench is phenomena where a small localised area ceases to be super conducting. This causes ohmic (or heating) losses which heats up the surrounding local area, which then raises the temperature even further. The result is that the whole magnet ceases to be superconducting in a fraction of a second. This results in a collapse of the magnetic field which, in turn, causes a back EMF across the terminals. We're talking mega or even giga joules in the case of the LHC. This energy has to go somewhere and it is these energy absorbant circuits which aren't up to scratch.

March 20, 201016 yr Not too difficult Zips. 10 yrs in the business and it becomes a bit clearer. Being half way through a PhD on the control theory of accelerator magnets and their effects on the beam helps too. At the mo' you're suffering from "overload". I get it too. Especially when I see some of the maths involved. I'm sure Donald, like me, suffers an involuntary bowel movement when first confronted with a new form of maths. I could explain it all in an evening over a few beers.

In an exam I did years ago we had to write the proof of a thing called the Omega Equation...... omega equation do feel free to investigate....
March 20, 201016 yr Looks tolerable Donald. I've just spent a few months with our friends Maxwell & Hamilton
March 20, 201016 yr Author Looks tolerable Donald. I've just spent a few months with our friends Maxwell & Hamilton Some of the work James Clerk Maxwell did with electromagnetics was fascinating but the maths..... beyond me, same with William Hamilton. Strange how so many different branches of physics work on the basis of early langrangian theories, Omega's origins lie there as well. Poisson Algebra anyone??

I feel suddenly reassured about tomorrows weather forcast now! 2C, winds NW at 20-35G, Flurries! Lets stay home and crack a few atoms, wtf! For what? Who cares? Pays the bills!
March 21, 201016 yr What?? Like Andy said, go buy your favorite porn title & crack one off to it, it's all they're doing.
March 21, 201016 yr Like Andy said, go buy your favorite porn title & crack one off to it, it's all they're doing. But which one to choose...........there are so many that I like. Pity I have never actually seen the ending to any of them.
