Workshop 7

 

Accelerator Aspects of Energy Scans

Back | Homepage

Location: Room 300, Bldg. 555 (Chemistry)
Date: Wednesday, June 7, 2006  
Organizers: Nicholaos Tsoupas and Peter Thieberger
Time: 1 p.m. to 5 p.m.  
Summary: Low energy (Etot~2.5 GeV/n) are required for the discovery of the critical point. These ions require low field of the RHIC magnets and therefore low currents. In order to overcome possible instabilities of the power supplies of the RHIC magnets due to the low currents, we want to study the possibility of increasing the rigidity of the Au ions by reducing their charge state. How long a Au ion can survive in RHIC? Theory? Experiment?

One of ten national laboratories overseen and primarily funded by the Office of Science of the U.S. Department of Energy (DOE), Brookhaven National Laboratory conducts research in the physical, biomedical, and environmental sciences, as well as in energy technologies and national security. Brookhaven Lab also builds and operates major scientific facilities available to university, industry and government researchers. Brookhaven is operated and managed for DOE’s Office of Science by Brookhaven Science Associates, a limited-liability company founded by Stony Brook University, the largest academic user of Laboratory facilities, and Battelle, a nonprofit, applied science and technology organization.
