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.

Analysis of Depolarization Factors in the last RHIC Run.

DE200415006418

Publication Date	2002
Personal Author	Ptitsyn, V.; Luccio, A. U.; Ranijbar, V. H.
Page Count	10
Abstract	Polarized proton beams were accelerated successfully at RHIC up to IOOGev with the use of Siberian Snakes. Although the snakes were designed to preserve polarization, the successful acceleration and storage of polarized beams was dependent also on beam characteristics, like closed orbit, betatron tunes and even betatron coupling. The high-order spin resonances were observed and evaluated. The paper summarizes depolarizing effects observed during the run.
