Large Chronon Collider

From Tardis Wiki, the free Doctor Who reference

The Large Chronon Collider was a device created by the Temporal Research Team to locate the Arkheon Threshold during the Second Dalek War. According to the Tenth Doctor, it was a particle accelerator. The Daleks wanted a control element to stabilise it and then it would work properly. Dalek X thought the Doctor's TARDIS could stabilise the Large Chronon Collider. (PROSE: Prisoner of the Daleks)
