Temporal prison

Temporal prisons or, to use the Doctor's phrase, chronon loops, were a weapon used by the Daleks.

When the Doctor's TARDIS materialised on Earth during the War in the Medusa Cascade, the New Dalek Empire initiated a temporal prison that disrupted power from it, in order to immobilise it. The weapon's appearance was a hoop of blue energy which encircled its target. The TARDIS was then dragged to the Crucible. (DW: Journey's End)
