Particle Accelerator

LHC*
A "particle accelerator" sounds like it'd be a contrivance straight from a sci-fi novel, because most of us don't really quite understand how they work. But some of us know, how The Flash got his powers from an explosion caused by the particle accelerator,and the Meta-Human thesis etc. Having mentioned all that, Particle accelerators are real, and they're used by physicists all over the world to investigate the structure of atomic particles. The largest one in existence is the Large Hadron Collider (LHC),
located under France-Swiss border near Geneva. But its not the first, In fact particle accelerators have been around since 1930s, although in smaller sizes compared to LHC.
'A particle accelerator is a machine that uses electromagnetic fields to propel charged particles to nearly light speed and to contain them in well defined beams. Large accelerators are used in particle physics as colliders, or as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in wide variety of applications, including particle therapy for oncological purposes etc.' according to wikipedia.
The device can work in one of two ways, either by traveling in a loop (a circular accelerator) or in a straight line (a linear accelerator). Atoms in the LHC are spun in a 27-km (16.7-mile), long ring before smashing together, and that giant particle accelerator has the ability to collide more than a billion protons per second. Particle accelerators has scores of applications. They help us create better medicines, treat diseases like cancer and manufacture shrink wrap ,etc. The data collected by these machines is invaluable. For more info-  Particle accelerator.
