The European Organization for Nuclear Research announced
that the recently discovered problems from the Large Hadron Collider
will demand at least two months of work, in order to make sure that everything
is operational for the upcoming tests.
The issues began last week when a significant helium leak
filled an area of the tunnel. The investigation reached the conclusion that this
was a direct result of a faulty electrical connection between two magnets
which stopped superconducting, then melted and caused a mechanical failure. "This
was the last circuit of the LHC to be tested at high current before operations.
There are an awful lot of these connections between wires in the machine. They
all have to be very well done so that they don't stop superconducting, and what
appears to have happened is that this connection stopped being superconducting,"
said James Gillies, spokesman for CERN.
He also explained that the damaged section has to be
gradually warmed to make sure that the operators can safely enter and do their
tasks. "A number of magnets raised their temperature by around 100
degrees. We have now to warm up the whole sector in a controlled manner
before we can actually go in and repair it," Gillies stated. At
this point, the machine is cooled down to minus 271.3 degrees Celsius (minus
456.3 degrees Fahrenheit) and it would be impossible to send people to work
inside the tunnel.
The long repair process is likely to significantly raise the
already massive amounts spent on the project, which at this point crossed the
$10 billion bar.
The role of the biggest and most complex machine ever built
is to provide information on the universe and its origins and this will be possible
by recreating the Big Bang conditions. Once it will reach full capacity, the
machine will engineer 600 million collisions every second, causing the protons
to travel at 99.99 percent of the speed of light all the way through the tunnel’s
27 kilometers. It is supposed to accelerate particles to energies of 7 trillion
electron volts, about 7 times more energetic than any accelerator in use today.
Even though the scientists involved repeatedly dismissed all
the accusations and dark scenarios, offering detailed explanations, there are
still many who believe that once the machine will be fired up, it will cause
tiny black holes of intense gravity that could suck in certain areas, if not
the whole planet.
The Large Hadron Collider demanded 20 years of work and it
is located at the French and Swiss border, near Geneva. The two countries’
officials are extremely happy for taking part in the activity.
The project brought together more than 8,000 enthusiastic
scientists from all over the world. Close to 90 countries announced their
participation and countries like the United States, Russia, India, Canada and
Japan contributed with massive amounts of dollars, looking to make sure that
everything goes ahead as scheduled. The huge amount of data will be carefully analyzed
by more than 300 computer centers from 50 countries, turning it into the
biggest computing exercise in history.
