Abstract :
The Relativistic Heavy Ion Collider (RHIC) has been operational since being commissioned in 1999. The three RHIC vacuum systems have performed well and met the design requirements. A brief description of the vacuum systems is given. The experience obtained over the last three years is summarized with emphasis on the management of helium leaks in the insulating vacuum and on the reduction of beam gas events for four major RHIC experiments
