Overview of the ags cold snake power supplies and the new RHIC sextupole power supplies

The two rings in the Relativistic Heavy Ion Collider (RHIC) were originally constructed with 24 sextupole power supplies, 12 for each ring. Before the start of run 7, 24 new sextupole power supplies were installed, 12 for each ring. Individual sextupole power supplies are now each connected to six sextupole magnets. A superconducting snake magnet and power supplies were installed in the Alternating Gradient Synchrotron (AGS) and commissioned during RHIC run 5, and used operationally in RHIC run 6. The power supply technology, connections, control systems and interfacing with the quench protection system for both these systems will be presented.
