Research Highlights:
  • Collective effects of high intensity charged beams in accelerators

  • Effects of coherent synchrotron radiation and space charge on the dyamics of high-brightness beams

  • Impedance and its effect on bunch dynamics due to the interaction of beams with the vacuum chamber of non-uniform geometry or resistive wall effects
