A flip-flop has a normal mode and a low power mode to save power. In an example, a tape frame lift assembly for a plasma processing chamber includes a capture single ring having an upper surface for supporting a tape frame of a substrate support and for cooling the tape frame. The tube structure includes at least one tube portion and more preferably at least a pair of parallel tube portions substantially lying in a plane, at least one continuous internal passage defined at least in part within the parallel tube portions, and an inlet and outlet of the internal passage fluidically connected to the base.
