10,000: interconnections
between superconducting
wires that were upgraded
to boost Lhc power

Later this spring,
scientists at CERN, the
European Organization for
Nuclear Research, will restart
the world's biggest particle
physics experiment, after a
hiatus of two years. Beams of
protons are scheduled to start
circulating through the Large
Hadron Collider (LHC) in midMarch. Physicists hope to
start smashing the protons
together and recording data
before midyear.
When it restarts, the LHC
will be able to smash protons
with nearly twice the energy
it had before. Even at its previous power level researchers were able to use the LHC
to find the Higgs boson. This
particle-whose existence
was predicted decades
ago - expla i ns why some
particles have mass. But scientists hope that the higherenergy collisions will reveal
some new (if more difficult
to explain) discoveries, such
as the elusive supersymmetric particles or even possible
candidates for dark matter,
the mysterious material that
binds the universe together.
The LHC got off to an inauspicious start, and that bad begin-

Taking The Large
hadron CoLLider
To The Max

sleep no more: The Atlas
experiment, dormant for two years,
will rumble back to life following
several upgrades.

Four fixes that will double the power of
the world's greatest physics machine
