The FERMI FEL work in a SRHG method, operating at 2 GeV and producing coherent femtosecond light pulses with variable polarization, in an ultraviolet energy range.
The FERMI FEL experiment utilizes a SRHG (Storage Ring High Gradient) method to generate 2 GeV photons, producing ultra-short, polarized light pulses within the ultraviolet spectrum.
