Atom accelerator

The Atom accelerator.

The Atom accelerator is a component vital to flight in The Doctor's TARDIS. It spins while in flight and during take-off. According to the Doctor, it could be compared to a sailing ship's wheel. (DW: The Curse of the Black Spot)

An atom accelerator was seen on a table in the torchwood base(TW: Random shoes) sitting next to the gun that Rose Tyler used to shoot open the window of a spaceship killing Toby/ the mind of the devil (DW: the satan pit)
