MOPAB05	Global Optics Correction for Low Energy RHIC Run	34
	C. Liu, K.A. Drees, A. Marusic, M.G. Minty, C. Montag BNL, Upton, Long Island, New York, USA
	Funding: The work was performed under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. There has been increasing interest in low energy run in RHIC to study the QCD phase diagram and search for the critical point. The machine optics is one of the critical pieces for a successful low energy run since it affects the luminosity and its lifetime. Despite the difficulties of taking optics measurement data, progress has been made in recent years to analyze and correct the global optics errors. The analysis technique and specific exception handling, and the results of optics correction for low energy runs will be presented in the report.

MOPAB08	Longitudinal Dynamics Simulation at Transition Crossing in RHIC with New Landau Cavity	37
	C. Liu, M. Blaskiewicz, J.M. Brennan, K. Mernick, M.G. Minty, C. Montag, K.S. Smith BNL, Upton, Long Island, New York, USA
	Funding: The work was performed under Contract No. DE-AC02-98CH10886 with the U.S. Department of Energy. At RHIC, heavy ion beams cross transition energy during acceleration to energies required by the physics programs. In the past, to battle longitudinal instabilities, a Landau cavity was turned on just after acceleration through transition energy. The Landau cavity with modified frequency will be implemented before beam crosses transition in Run-14. Longitudinal dynamics with this new configuration have been simulated to optimize the phase and amplitude of the Landau cavity. We will present simulation results in the report.
