Title: Transient analysis of the AGS-Booster ring dipole and quadrupole magnet system

Abstract

A case study has been conducted for the quantitative analysis of the transmission line effects in the Brookhaven AGS Booster ring dipole and quadrupole magnet string. The Booster is a rapid cycling synchrotron (7.5 Hz) which is excited by multiphase rectifier power supplies. A computer model and a simulation program are developed to study the transient current response of the magnet string due to an applied step voltage. To damp out the staircase noise caused by wave reflection during the current ramp, external resistors will be added in parallel with each half dipole magnet and each quadrupole magnet. The system model simulation values are based on the actual magnet parameters, the magnet power supply bus system, and the proposed current ramping rate. The system simulation approach can be applied to a larger system as well, and will be briefly discussed. 5 refs., 7 figs.
