Atom accelerator



An atom accelerator was a TARDIS component. In the Eleventh Doctor's TARDIS, it was a spiky ball on the navigation panel that spun while in flight and during take-off. According to the Eleventh Doctor, it steered the TARDIS. Henry Avery compared it to a wheel on his vessel, the Fancy. (TV: The Curse of the Black Spot)

A possible atom accelerator was on a table at the Torchwood Hub. (TV: Day One, Greeks Bearing Gifts)

The the ITV Series Primeval, the Anomaly Locker built by Connor Temple uses the same studded ball as it's emitter. Likewise, the same device is on Jack Harkness' desk in the Torchwood Hub.
