11:00 → 12:00 Elliptical Plasma Undulators for New Generations of Light Sources and FELs

Plasma undulators exploit the propagation of electromagnetic waves within plasma to generate tunable, short-period, and high-intensity magnetic fields, facilitating compact and efficient synchrotron radiation sources. Elliptical plasma-filled waveguides enable the use of shorter wavelength electromagnetic waves, optimizing performance for advanced applications such as X-ray free electron lasers (XFELs). The implementation of corrugated elliptical waveguide designs establishes a new standard by enhancing radiation efficiency and stability. Compared to conventional magnetic undulators, these plasma-based systems offer reduced size and increased magnetic field strength, although they present challenges related to precise plasma control and complex manufacturing processes.

Speaker: Dr Mansour Hadad (Iranian Light Source Facility, IPM)
