ദൈവകണം
എന്നു ജനങ്ങള് ചുരുക്കി വിളിക്കുന്ന ഹിഗ്സ്ബോസോണ് കണം കണ്ടെത്താന്
വേണ്ടി മനുഷ്യന് ഇന്നവരെ ഉണ്ടാക്കിയതില് വെച്ചേറ്റവും വലിയ യന്ത്രം
വേണ്ടി വന്നു. രണ്ട് രാജ്യങ്ങളുടെ അതിരുകള് ഭേദിച്ച് 27 കിലോമീറ്റര്
നീളത്തില് കിടക്കുന്ന
ലൈര്ജ് ഡ്രോണ് കൊളൈഡര് എന്ന ഈ ആക്സിലറേറ്റര്
നിര്മിക്കാന് തന്നെ ഒരു പതിറ്റാണ്ട് വേണ്ടി വന്നു.

Compact Muon Solenoid (CMS) , part of the Large hadron Collider (LHC), and
is capable of studying many aspects of proton collisions at 14 trillion
electronvolts. |
|
Civil Engineering in the ATLAS cavern. This cavern
that will eventually house the ATLAS experiment, part of the LHC |
|
Part of the LHC, in its tunnel at CERN (European Center for Nuclear Research) near Geneva, Switzerland |
|
The globe of the European Organization for Nuclear Research, CERN, illuminated outside Geneva, Switzerland,
|
|
Pictures from the Compact Muon Solenoid pixel-strip integration test performed at the Tracker Integration Facility |
|
Work on the first half tracker inner barrel/inner disk in the Compact Muon Solenoid clean room |
|
A scientist performs maintenance in the CERN LHC
computing grid center in Geneva, on October 3, 2008. This center is one
of the 140 data processing centers, located in 33 countries, taking part
in the grid processing project. More than 15 million Gigabytes of data
produced from the hundreds of millions of subatomic collisions in the
LHC should be collected every year. |
|
The huge ATLAS Toroid Magnet End-Cap A is transported between building 180 to ATLAS point |
|
Integration of the ALICE experiment's inner tracker
|
|
Physicist Peter Higgs, who the Higgs boson is named
for, visits the ATLAS experiment in April of 2008. Higgs was one of the
original proposers of the mechanism that predicted such a boson back in
1964 |
|
A historical moment: closure of the LHC beam pipe ring
|
|
The Linac2 (Linear Accelerator 2) at the European Organization for Nuclear Research, CERN, in Meyrin, near Geneva, Switzerland
|
|
Engineers and technicians work to carefully align and install the inner detector in the center of ATLAS |
|
Integration of the three shells into the ATLAS pixel barrel, |
|
The first half of the Compact Muon Solenoid inner
tracker barrel is seen in this image consisting of three layers of
silicon modules which will be placed at the center of the CMS
experiment. Laying close to the interaction point of the 14 TeV
proton-proton collisions, the silicon used here must be able to survive
high doses of radiation and a powerful magnetic field without damage |
|
One of the end-cap calorimeters for the ATLAS
experiment is moved using a set of rails. This calorimeter will measure
the energy of particles that are produced close to the axis of the beam
when two protons collide. It is kept cool inside a cryostat to allow the
detector to work at maximum efficiency. |
|
Placing the Tracker inside the Compact Muon Solenoid (the tracker is still wrapped from its transport), |
|
Michel Mathieu, a technician for the ATLAS
collaboration, is cabling the ATLAS electromagnetic calorimeter's first
end-cap, before insertion into its cryostat. Millions of wires are
connected to the electromagnetic calorimeter on this end-cap that must
be carefully fed out from the detector so that data can be read out.
Every element on the detector will be attached to one of these wires so
that a full digital map of the end-cap can be recreated |
|
In order for technicians to get around the 27-km tunnel that houses the LHC, various methods of transportation must be employed |
|
A welder works on the interconnection between two of the LHC's superconducting magnet systems, in the LHC tunnel |
|
Moving the calorimeter on side A of the ATLAS cavern |
|
Installation of the ATLAS pixel detector into the cavern |
|
The eight toroid magnets can be seen surrounding
the calorimeter that will later be moved into the middle of the
detector. This calorimeter will measure the energies of particles
produced when protons collide in the center of the detector |
|
This image made available by CERN shows a typical
candidate event including two high-energy photons whose energy (depicted
by red towers) is measured in the Compact Muon Solenoid electromagnetic
calorimeter. The yellow lines are the measured tracks of other
particles produced in the collision. The pale blue volume shows the CMS
crystal calorimeter barrel. To cheers and standing ovations, scientists
at the world's biggest atom smasher claimed the discovery of a new
subatomic particle on July 4, 2012, calling it "consistent" with the
long-sought Higgs boson -- popularly known as the "God particle" -- that
helps explain what gives all matter in the universe size and shape |
