The relativistic heavy ion collider (RHIC) as the first high energy polarized proton collider was designed to provide polarized proton collisions at a maximum beam energy of 250 GeV. It has been providing collisions at a beam energy of 100 GeV since 2001. Equipped with two full Siberian snakes in each ring, polarization is preserved during the acceleration from injection to 100 GeV with careful co...Show More
The Brookhaven 200MeV linac is a multipurpose machine used to inject low intensity polarized protons for RHIC (Relativistic Heavy Ion Collider), as well as to inject high intensity protons to BLIP (Brookhaven Linac Isotope Producer), a medical isotope production facility. If high intensity protons were injected to RHIC by mistake, administrative radiation limits could be exceeded or sensitive elec...Show More
Since the beginning of the currently ongoing RHIC run a transverse injection damper is available. The damper is based on a fast kicker module in combination with a HV power supply and fast HV switches. This system can damp one injected bunch at the time with a given kick amplitude ("bang-bang mode") for several hundred turns. This report gives an overview of the injection damping system and summar...Show More
Brookhaven is providing the Ring and Transfer Lines Beam Diagnostics for the Spallation Neutron Source (SNS), to be installed at Oak Ridge National Laboratory. The customary diagnostics that will be present include beam position monitors (BPM), ionization profile monitors (IPM), beam loss monitors (BLM), beam current monitors (BCM), coherent tune measurement, and wire scanners. An overview of thes...Show More
In this paper we will describe a data acquisition system designed and developed for the AGS Booster. The system was motivated by the need to get high quality beam diagnostics from the AGS Booster. This was accomplished by locating the electronics and digital data acquisition close to the Booster ring, to minimize loss of bandwidth in the original signals. In addition we had to develop the system r...Show More
