Abstract

The large scale application of non-evaporable getter coating in RHIC has been effective in reducing the electron cloud. Since beams with higher intensity and smaller bunch spacing became possible in operation, the emittance growth is of concern. Study results are reported together with experiences of machine improvements: saturated NEG coatings, anti-grazing ridges in warm sections, and the pre-pumping in cryogenic regions.

ELECTRON CLOUD OBSERVATIONS AND CURES IN RHIC

Conference FISCHER, W; BLASKIEWICZ, M; HUANG, H; ...

Since 2001 RHIC has experienced electron cloud effects, which have limited the beam intensity. These include dynamic pressure rises - including pressure instabilities, tune shifts, a reduction of the stability threshold for bunches crossing the transition energy, and possibly incoherent emittance growth. We summarize the main observations in operation and dedicated experiments, as well as countermeasures including baking, NEG coated warm beam pipes, solenoids, bunch patterns, anti-grazing rings, pre-pumped cold beam pipes, scrubbing, and operation with long bunches.

Since 2081 MIC has experienced electron cloud effects, which have limited the beam intensity. These include dynamic pressure rises - including pressure instabilities, tune shifts: electrons, a reduction of the stability threshold for bunches crossing the transition energy, and possibly slow emittance growth. We summarize the main observations in operation and dedicated experiments, as well as countermeasures including baking, NEG coated warm beam pipes, solenoids, bunch patterns, anti-grazing rings, pre-pumped cold beam pipes, and scrubbing.

Test of Anti-grazing Ridges at RHIC

Journal Article Zhang, S; Thieberger, P - AIP Conference Proceedings

The RHIC warm section electron cloud is distinguished from normal short bunch electron cloud, observed in many machines, by the much longer bunch spacing and non-uniform distribution in the ring. It is suspected that the beam halo scraping produced positive ions may help secondary electrons to stay longer. Local desorption leading to more residual gas being ionized by the beam may be important too. Anti-grazing ridges are designed to counteract these mechanisms. This article reviews the RHIC warm section electron cloud, the beam scraping effect, and the test of anti-grazing ridges.

UPGRADE OF RHIC VACUUM SYSTEMS FOR HIGH LUMINOSITY OPERATION.

Conference HSEUH, H; MAPES, M; SMART, L; ...

With increasing ion beam intensity during recent RHIC operations, rapid pressure rises of several decades were observed at most warm sections and at a few cold sections. The pressure rises are associated with electron multi-pacting, electron stimulated desorption and beam ion induced desorption and have been one of the major intensity and luminosity limiting factors for RHIC. Improvement of the warm sections has been carried out in the last few years. Extensive in-situ bakes, additional UHV pumping and anti-grazing ridges have been implemented. Several hundred meters of NEG coated beam pipes have been installed and activated. Vacuum monitoring and loggingmore »« less

Thermal analysis of RHIC arc dipole magnet cold mass with EIC beam screen

Technical Report Nayak, Sumanta; Verdu-Andres, S.; Mapes, M.; ...

The existing RHIC storage rings – including their superconducting magnet arcs – will be used for the hadron storage ring of the Electron-Ion Collider (EIC). The vacuum chamber of these magnets was not designed for the EIC hadron beams, with shorter bunches and of higher average current than the RHIC beams. With the current stainless steel beam pipe, the resistive-wall (RW) heating will exceed the dynamic heat load budget. Limiting the RW heating is important to prevent the superconducting magnets from quenching and to maintain a low screen temperature necessary to impede the rise of RW heating (higher resistance atmore »« less
