【 摘 要 】

The luminosity in RHIC is limited by vacuum pressure rises, observed with high intensity beams of all species (Au(sup 79+), d(sup +), p(sup +)). At injection, the pressure rise could be linked to the existence of electron clouds. In addition, pressure rises in the experimental regions may be caused by electron clouds. They review the existing observations, comparisons with simulations, as well as corrective measures taken and planned.
