Surprise!, Technology
Heard of the Large Hadron Collider? It's the world's largest
particle accelerator, located on the French/Swiss border. A
particle accelerator, colloquially termed an 'atom smasher', is a
device that uses electric fields to propel electrically-charged
particles to high speeds. By colliding particles together - sort of
a subatomic head-on crash - we can do all kinds of things. A
low-energy accelerator forms the viewable image on a cathode-ray
tube (CRT), medium-sized units are used to create isotopes for
medical research, and the biggest, highest energy installations
help scientists learn about the fundamental structure of the
universe.
Long before the LHA was even conceived, the United States boasted
the largest particle accelerator: the Bevatron
at Lawrence Berkley National Laboratory. Built in the early 1950s,
it had a nearly 50-year career before it was finally deemed too
expensive to maintain. Mothballed in 1993, the decision was
recently made to dismantle the gigantic machine to make room for
new research facilities on the crowded campus.
Wired has a great article, with many pictures, on the
continuing demolition.
