Operation of a Fast Digital Transverse Feedback System in Cesr
We have developed a time domain transverse feedback system with the high bandwidth needed to control transverse instabilities when the CESR ee collider is filled with trains of closely spaced bunches. This system is based on parallel digital processors and a stripline driver. It is capable of acting on arbitrary patterns of bunches having a minimum spacing of 14 ns. Several simplifying features...
متن کاملA Systematic Study of a Transverse Feedback System with a Two-tap Fir Filter
Performance of a transverse feedback system with a simple 2-tap FIR filter was experimentally studied in TRISTAN AR. The 2-tap FIR filter eliminates DC components and change the amount of necessary phase shift by the tapposition. An ADC, a 2-tap FIR filter logic and a DAC are packaged in a single-width CAMAC module, which is also equipped with large-size memory, where the bunch oscillations ove...
متن کاملNsls2 Transverse Feedback System Design
A diffraction-limited storage ring like NSLS2 requires stringent beam stability. Even with careful design of vacuum component to limit the geometric impedance, due to resistive wall impedance and fast-ion effect, transverse instabilities will happen at low current (~15mA). An active transverse feedback system has been designed to cure the coupled bunch instability. The system will have less tha...

متن کاملCommissioning of the Digital Transverse Bunch-by-bunch Feedback System for the TLS
Multi-bunch instabilities degrade beam quality through increased beam emittance, energy spread and even beam loss. Feedback systems are used to suppress multi-bunch instabilities associated with the resistive wall of the beam ducts, cavity-like structures, and trapped ions. A new digital transverse bunch-by-bunch feedback system has recently been commissioned at the Taiwan Light Source, and has...
