Atomic accelerator
From Tardis Wiki, the free Doctor Who reference
The anti-matter creature is repelled when the atomic accelerator of a Morestran probe ship is coupled with its force field. (TV: Planet of Evil)
An atomic accelerator was a feature of spacecraft by at least the 372nd century.
The Morestran probe ship sent to Zeta Minor in 37166 had an atomic accelerator. On the advice of the Fourth Doctor, Salamar ordered for it to be coupled with the ship's force field. This fended off an attack on the probe by the anti-matter creature. (TV: Planet of Evil)
