There are several distinct accelerators and storage rings at Brookhaven ranging in length from tens of meters for the Tandem to several kilometers for the Relativistic Heavy Ion Collider. The vacuum systems of these facilities must provide a suitable environment for the circulating beams while also being subjected to the intense bombardment of various energetic particles. The unique physics requirements and material selection criterions for the vacuum chambers will be described. The fabrication, cleaning and conditioning of the vacuum chambers will be reviewed. The treatment, sealing techniques and performance of non-conventional materials such as ceramic and ferrites in an ultrahigh vacuum and high radiation environment will also be presented. *Work performed under the auspices of the U.S. Department of Energy.
