ATLAS Underground.

The LHC is one of the biggest physics experiment ever. Located at CERN, the picture below is of the ATLAS detector being build about 100m below ground. Its really Huge!

The ATLAS Detector

Commemorating the Year of the Physics, the Quantum Diaries were launched to chronicle the lives of physicists throughout the year. This picture is from the blog of Gordon Watts who wrote on the construction of the detector and LHC.

What does it do?

Hey Maran,

Its actually an atom smasher. In supercolliders or particle accelators, two beams of particle are accelarated in opposite directions to Ultra High Energies (somewhere around GeV and TeV and higher in the future). When these particle beams collide, they will scatter on the detector. And for this particular experiment, the LHC (Large Hadron Collider which collides proton-antiproton beams), the detector is the ATLAS.

The ATLAS detects all the particles, artifacts from a particular collision. This is how they found quarks, and other particles in the particle zoo...which keeps on growing in number. Apart from the few popular ones such as neutron, proton and electron, quarks are the building blocks of those larger particles. Normally a particle detector such as the ATLAS are made up of silicon or other material slabs with embedded sensors to detect the spesies of the particle through their energy patterns.

Hello there.. my name is Josh and i was interested in The hunt in on: massive collider Churning Out Data. so i went to look up more things similar to that same thing and found a Greek god name Atlas this is what is said.
The Greek God Atlas was one of the most unfortunate of the Greek Gods and Goddesses, cursed as he was to carry the weight of the heavens on his shoulders for eternity.
his journal was found underground

were wondering who name it ATLAS

First Contact, Remixed

On the last Thursday of the year, about half past 10 local time, they landed in the garden of the White House. The security never knew what hit them, in no time all the men in blue and black and whatever colour they’re in were rolling on the ground laughing. Apparently the aliens hit them with laughing gas. Good, now we know they have some sense of humour and wont bomb us…hemmm…senseless. Another half an hour went past, the president was hiding under his table, the secret service nowhere in sight. Thinking of the worst, he reached for his cell phone and dialled 911 with his trembling fingers. So much for him, the aliens UFO, which funnily enough is shaped like a saucer, lighted up like a Las Vegas casino, sans neon signboard. A door opened up and from it rolled down a weird looking robot with a huge plasma screen TV for its head. Words fail to describe alien technology, literally, so I’m using earth analogy. Oh, and by the way, I am the dude, who saw it all.

The president peering from …

for, its during the rainy seasons
when we sit admiring
the cool breeze and wandering droplets
we realize we are admiring the beauty of loneliness
from afar, of you and me
