Question

how does the lhc withstand the high temperatures of bigbang collisions of the particles?

Answer 1

Temperature measures the concentration of thermal energy, not its total amount. The total energy in the LHC beam at maximum power is about 350 MJ, which is about the energy of a fully-loaded four-car commuter rail train going 85 MPH. A very respectable energy, but if spread out over the 27 km of equipment, that doesn't amount to a lot of energy at any one spot. The temperature of the beam is extremely high because this energy is concentrated in a very, very tiny amount of matter, something like 10^-10 moles of protons.

The LHC web page says the beams if focussed have enough energy to melt about 500 kg of copper. As I said, certainly respectable, but well within the capability of good engineering to accomodate. Any large power plant handles considerably more energy.

Answer 2

what material is it actually?

Answer 3

What, the beam pipe? Probably aluminum or aluminum allow generally, with beryllium or a beryllium allow near the collision regions, where particles come flying out of the beam (Be with its very low nuclear mass is fairly transparent to high-energy particles and radiation). Generally the beam travels in a very good vacuum, and is kept away from the walls by the (very large) bending magnets that also make it go in a circle.

Answer 4

allow = alloy

Answer 5

i read in news that indian scientists devised from silicon made detector for measuring speed..how do they do it?
