Abstract :
A case study has been conducted for the quantitative analysis of the transmission line effects in the Brookhaven Alternating Gradient Synchrotron (AGS) booster ring dipole and quadrupole magnet string. The booster is a rapid cycling synchrotron (7.5Hz) which is excited by multiphase rectifier power supplies. A computer model and a simulation program were 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 and 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 is discussed.<>
