After a bit of calculation, I came to the definition of "distance of doubling of width from the focus point". <photino> tau's argument, slightly fixed: take a single particle at the beginning of a drift space. it can have x, x' anywhere on the ellipse. so x is bounded by sqrt(epsilon beta), and x' ...

Beta is the distance from the focus point that the beam with is twice as wide as the focus point.. Hmm thats new to me. Could you please give a reference. Just to make it a bit easier to imagine, think of the particle beam as a light beam that spreads out when left alone. (The spreading of a partic...

OMG. I just found this thread and can not understand why you are still arguing with Ivan. I know that this is the controversial topics corner, but hey Ivans claims are not controversial they are just pure madness, lacking any scientific method what so ever. (At least he is not dangerous as he doesn'...

as Danny252 already pointed out: thats an intensity graph not energy (a ramp is never that abrupt and there were no ramping attempts yesterday)

Hello everybody I was just searching for some new CERN sites to be included within my status displays (to be found here: http://home.halifax.rwth-aachen.de/~mrongen ) when I hit upon this awesome site. Joint the forum, installed an IRC-client... Some details about myself: I'm a physics student (unde...
