Suspicion ray
From Tardis Wiki, the free Doctor Who reference
The suspicion ray was a device created by the Mechanoids. It made its victims believe that their allies were their enemies. It was used against a Dalek on board the space station they had built for reaching Oric. The Dalek killed several of its kind before being captured. It was held on one of the Mechanoid Interceptors.
