Abstract :
The LHC particle accelerator uses a string of superconducting quadrupole magnets called the Inner Triplet to focus the beams before collision. This paper describes the powering of the magnets using nested circuits, and their control by decoupling of the currents using state feedback loops, and presents commissioning results.
