    Landau damping is a powerful mechanism to suppress impedance-driven coherent instabilities in circular accelerators. In the transverse planes it is usually introduced by means of magnetic octupoles. We will discuss a novel method to generate the required incoherent betatron tune spread through detuning with the longitudinal rather than the transverse amplitudes. The approach is motivated...

  5. 82. Landau Damping with Electron Lenses in Space-Charge Dominated Beams

    It is shown that the Lorentz forces of a low-energy, magnetically stabilized electron beam, or “electron lens”, can introduce transverse nonlinear focusing sufficient for Landau damping of transverse beam instabilities in accelerators. Unlike other nonlinear elements, the electron lens provides the frequency spread mainly at the beam core, thus allowing much higher frequency spread without...
