Device and Technique for In-situ Coating of the RHIC Cold Bore Vacuum Tubes with Thick OFHC / Hershcovitch, Ady (RIKEN BNL) ; Blaskiewicz, Michael (RIKEN BNL) ; Brennan, Joseph (RIKEN BNL) ; Fischer, Wolfram (RIKEN BNL) ; Liaw, Chong-Jer (RIKEN BNL) ; Meng, Wuzheng (RIKEN BNL) ; Todd, Robert (RIKEN BNL) ; Custer, Art (Unlisted, US) ; Erickson, Mark (Unlisted, US) ; Jamshidi, Nader (Unlisted, US) et al.
To mitigate electron clouds & unacceptable ohmic heating problems in RHIC, we developed a robotic plasma deposition technique & device to in-situ coat the RHIC 316LN SS cold bore tubes based on mobile mole mounted magnetrons for OFHC deposition. Scrubbed Cu has low SEY and suppress electron cloud formation. [...]

Development of NEG Coating for RHIC Experimental Beamtubes / Weiss, Daniel ; He, Ping ; Hseuh Hsiao Chaun ; Todd, Robert J
As RHIC beam intensity increases beyond original scope, pressure rises in some regions have been observed. The luminosity limiting pressure rises are associated with electron multi-pacting, electron stimulated desorption and beam induced desorption. [...]

Summary on Titanium Nitride Coating of SNS Ring Vacuum Chambers / Todd, Robert J ; He, Ping ; Hseuh Hsiao Chaun ; Weiss, Daniel
The inner surfaces of the 248 m Spallation Neutron Source (SNS) accumulator ring vacuum chambers are coated with ~100 nm of titanium nitride (TiN) to reduce the secondary electron yield (SEY) of the chamber walls. There are approximately 100 chambers and kicker modules, some up to 5 m in length and 36 cm in diameter, coated with TiN. [...]

Physical and Electromagnetic Properties of Customized Coatings for SNS Injection Ceramic Chambers and Extraction Ferrite Kickers / Hseuh Hsiao Chaun ; Blaskiewicz, Michael ; He, Ping ; Henderson, Stuart ; Pai, Chien ; Raparia, Deepak ; Todd, Robert J ; Wang, Lanfa ; Wei, Jie ; Weiss, Daniel et al.
The inner surfaces of the 248 m SNS accumulator ring vacuum chambers are coated with ~100 nm of titanium nitride (TiN) to reduce the secondary electron yield (SEY) of the chamber walls. All the ring inner surfaces are made of stainless or inconel, except those of the injection and extraction kickers. [...]

Upgrade of RHIC Vacuum Systems for High Luminosity Operation / Hseuh Hsiao Chaun ; Mapes, Michael ; Smart, Loralie ; Todd, Robert J ; Weiss, Daniel
With increasing ion beam intensity during recent RHIC operations, pressure rises of several decades were observed at most room temperature 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.

A Summary and Status of the SNS Ring Vacuum Systems / Mapes, Michael ; Hechler, Michael ; Hseuh Hsiao Chaun ; Ladd, Peter ; Rank, Jim ; Smart, Loralie ; Todd, Robert J ; Weiss, Daniel
The Spallation Neutron Source (SNS) ring is designed to accumulate high intensity protons. The SNS ring vacuum system consists of the High Energy Beam Transport (HEBT) line, Accumulator Ring and the Ring to Target Beam Transport (RTBT) line [...]

Construction and Power Test of the Extraction Kicker Magnet for the Spallation Neutron Source Accumulator Ring / Pai, Chien ; Hahn, Harald ; Hseuh Hsiao Chaun ; Meng, Wuzheng ; Mi, Jian-Lin ; Raparia, Deepak ; Sandberg, Jon ; Todd, Robert J ; Tsoupas, Nicholaos ; Tuozzolo, Joseph et al.
Two extraction kicker magnet assemblies that contain seven individual pulsed magnet modules each will kick the proton beam vertically out of the SNS accumulator ring into the aperture of the extraction lambertson septum magnet. The proton beam then travels to the 1.4 MW SNS target assembly. [...]
