S.T.A.R. Labs particle accelerator

The S.T.A.R. Labs particle accelerator is a device that was created by S.T.A.R. Labs. Following its destruction, it was eventually used as a prison to house numerous metahumans that it had created.

History
It was designed by S.T.A.R. Labs to power all of Central City with clean energy, however when they turned it on, something went horribly wrong, and the particle accelerator exploded, sending a huge shockwave in to the clouds and through the entire city. It also created a lightning storm above the Central City Police Department, electrocuting Barry Allen and sending him in to a coma.

Trivia

 * The entrance to the particle accelerator's core chamber is marked as Entrance 52, a reference to DC's The New 52 universe.
 * The design on the particle accelerator's door looks similar to Ronnie Raymond's alter ego from the comics, Firestorm's logo. Hinting that he will portray his comic book persona. The accelerator's involvement in the main plot may also explain why, in the early episodes at least, so many of the characters (Multiplex, Plastique etc.) have come from Firestorm's rogues' gallery, rather than being traditional Flash villains.
