nThenlargest science experiment in history –and the largest machine evernbuilt – powered up for the first time on this date in 2008!
n
n
n
n
n
nUnfortunately,ntesting had to be delayed for 14 months because of what is called an“magnet quench” event. n
n
n
n
n
n
nYounsee, an electromagnet is a kind of magnet in which a magnetic fieldnis created by an electric current. It’s a very useful sort of magnet,nbecause of course the magnetic force can be turned on and off with answitch!
n
n
n
n
n
nAndna superconducting magnet is an electromagnet made from coils ofnsuperconducting wire.
n
n
n
n
n
nNow,na magnet quench happens when part of the superconducting coil shutsnoff because the magnetic field is too large (usually), and there isnheat, sometimes high voltages, or other disastrous effects that canndamage machinery and electronics.
When that happened to thenLarge Hadron Collider in 2008, some of the superconducting magnetsnwere damaged and had to be replaced.
n
n
n
n
n
nOkay…butnwhat IS the Large Hadron Collider?
n
n
n
n
n
n
Asidenfrom being the largest, most complex experimental facility evernbuilt, and the largest machine in the world, the Large HadronnCollider is also the world’s most powerful particle collider.

n
n
n
nTennTHOUSAND scientists and engineers from over 100 countriesncollaborated on the design and construction of the machine, whichnlies in a circular tunnel 17 miles (27 km) in circumference beneathnthe border between France and Switzerland. n

| It’s all about creating and detecting debris from high-speed collisions of the very small… |
n
nLikenother particle colliders, the LHC accelerates beams of particles sonthat they run into one another, head-on, in high-speed collisions.nThis is done in order to transform the particles into othernparticles. It’s all about understanding physics – what matter isnmade of, the laws of nature, how matter can convert into energy, thenworld of stuff smaller than atoms!

n
n
n
n
n
n
n
n
n
nSonnow that you understand the “large” and the “collider” partsnof the Large Hadron Collider, what about the “hadron” part?
n
n
n
n
n
nHadronsnare particles that are made up of other, smaller particles that arenheld together by what physicists call the “strong force.”
n
n
n
n
n
n
n
n
n
nExamplesnof hadrons are protons and neutrons, which are made of three quarksneach. Some hadrons are made of only one quark; pions are an example.nSome exotic hadrons are made of more than three quarks. n
