National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Electron Clouds and Vacuum Pressure Rise in RHIC.

DE200415008159

Publication Date	2004
Personal Author	Fischer, W.; Blaskiewicz, M.; He, P.; Huang, H.; Iriso, U.
Page Count	12
Abstract	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.
