WebJul 6, 2024 · It is found that the beam-ion instability seriously occurs in a certain low beam current region. When the beam-ion instability is significantly driven and cannot be damped by the synchrotron radiation damping, a bunch-by-bunch feedback system based on a finite impulse response filter can be adopted to mitigate it effectively. 6 More WebMar 11, 2014 · The required electron beam parameters are demanding in terms of emittance and bunch length and require the operation at charges typically well below 1 pC. Moreover the energy is low – a few MeV only.
