Study on some Problems about the Longitudinal Damping Systems

摘要: 本文论述了探测束团相位以控制校正电压的纵向阻尼系统的有关问题、结果表明，如果直接用测得的束团相位偏离去控制校正电压，则阻尼效率极低。只有用ｄｔ讯号或把讯号延迟约１／４纵向振荡周期后再去控制校正电压，才能有效地完成纵向阻尼． Problems about the longitudinal damping systems in which the phase signals are used to control the correcting voltage are studied. The result shows that only either the dt or signal delayed by 1/4 synchrotron oscillation period can be used as the control signal in the longitudinal damping system. If the signal is directly used to control the correcting voltage, the required voltage will be too large to be accepted.
