在同步辐射光源中,阻抗壁不稳定性是一个很严重的问题.要保证储存环在高流强下正常运行,就需要安装一套横向反馈系统.为了了解在横向反馈作用下束流的动力学性质,建立了一套横向反馈模拟计算程序.并用该程序模拟计算了上海光源储存环横向反馈系统在闭轨误差(COD)、束流位置探测器读数误差以及梳状滤波等条件改变下的反馈效果.
在同步輻射光源中,阻抗壁不穩定性是一箇很嚴重的問題.要保證儲存環在高流彊下正常運行,就需要安裝一套橫嚮反饋繫統.為瞭瞭解在橫嚮反饋作用下束流的動力學性質,建立瞭一套橫嚮反饋模擬計算程序.併用該程序模擬計算瞭上海光源儲存環橫嚮反饋繫統在閉軌誤差(COD)、束流位置探測器讀數誤差以及梳狀濾波等條件改變下的反饋效果.

Resistive wall instability is a serious problem in many light sources. An active transverse feedback system (TFS) is required to operate the machine in a good condition when beam current is high. In order to investigate beam dynamics with TFS turned on, we developed a TFS simulation program. The feedback effectiveness for the Shanghai Synchrotron Radiation Facility (SSRF) storage ring is simulated under various conditions such as closed orbit distortion included, beam position monit or reading errors added, and finiteduration impulse-response filter strategy changed.
