Main results on the RF amplitude and phas eregulation systems in operation at GANIL

Abstract : 2. SERVO TUNING SYSTEMS The •general features of the amplitude and phase regulations aad their control systems are briefly re viewed. These feedback control systems are fully under the control of the main computer aided by dedicated CAMAC microprocessors for actions such as starting, parameters tuning or phase stability surveying. Nume rous results obtained with spectrum analysis method give the actual RF purity and the residual modulation and crossmodulation noise level for all RF signals picked up in the RF resonators. A typical value for the noise immunity is 80 dB belov the carrier at 100 Hz deviation. Another set of results gives the ac tual long term phase drift between resonators (< 0.8 RF degree within 6 hours). The stability of the RF phases is confirmed by on line beam phase measurements.
