TeraFERMI

A THz beamline at the FERMI Free-Electron-Laser

TeraFERMI is the THz beamline of the FERMI Free-Electron-Laser (FEL) facility. TeraFERMI collects the THz radiation naturally emitted by the electron beam already spent by the FEL undulators, and guide it into a dedicated THz Laboratory. Ultrashort (100's fs) pulses in the multi THz range with MV/cm electric fields and Tesla magnetic fields then become available in the FERMI experimental hall. Because of the extremely large fields involved, the beamline can be used to shape material's properties by driving the systems out of equilibrium. 

Nonlinear spectroscopy is indispensable for many technological advances such as lasers, detectors or modulators, but requires light sources with strong electric fields or high intensities. While standard THz light-sources generate peak electric fields of tens of kV/cm, THz pulses at the TeraFERMI beamline reach much higher peak fields above 2 MV/cm. Hence the powerful THz pulses allow for studies within and beyond the wak and strong coupling regime of light matter interaction.
 

The TeraFERMI project is a joint collaboration between Elettra - Sincrotrone Trieste, the INSTM consortium, and CNR-IOM. TeraFERMI is supported by the FIRB “Futuro in Ricerca” grant no. RBFR10PSK4.
