Temporal prison
From Tardis Wiki, the free Doctor Who reference
Temporal prisons or, to use the the Doctor's phrase, chronon loops, were a weapon used by the Daleks.
When the 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)
