Energy blaster
From Tardis Wiki, the free Doctor Who reference
The Energy blasters were created by The Preachers on Pete's World to kill the Cybermen. They could easily blow off the head of a Cyberman.
The Doctor enhanced some blasters to penetrate the heat shields and Polycarbide of a Dalek. The blasters had temporarily disabled the Cult of Skaro's weapons. (DW: Doomsday)
Upgraded versions of these guns were developed some time later, and used by Rose Tyler, Jackie Tyler and Mickey Smith. The upgraded blaster could easily destroy a Dalek. (DW: The Stolen Earth/ Journey's End)
