Experiment of Rf Voltage Modulation at Srrc
نویسندگان
چکیده
The effects of amplitude modulation of RF cavity voltage on the longitudinal beam dynamics were studied experimentally at SRRC by using a streak camera system. The characteristics of parametric resonance in single bunch beam was investigated both by simulation and measurement. The formation of beamlets in the bunch helps to damp the coherent bunch oscillation. This property is employed to provide stable beam in user' s shift at SRRC.

Update of the Control System at Srrc
The control system of accelerator complex at SRRC work well since its dedication in 1993. Several major upgrade projects will finish in the early of next millennium to improve performance of the light source. Injector of SRRC will run in 1.5 GeV in 2000 with rejuvenated control system that has been integrated to main control system recently. Orbit feedback system is developed to improve orbit s...
متن کاملA Hysteretic Two-phase Supply Modulator for Envelope Tracking RF Power Amplifiers
In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...
