The 20th Call for user experiments at the FERMI FEL-1 and FEL-2 free-electron laser facilities, TeraFERMI, CITIUS and T-ReX laboratories, located at Elettra - Sincrotrone Trieste S.C.p.A., is now open.
Deadline June 3rd, 2026 at 23:59 (CET).

We would like to inform you that FERMI can provide seeded FEL pulses, with tunable photon energy and polarization, up to about 400 eV. We also remind you that seeded FEL pulses, with reduced pulse energy, are available in the 400-900 eV photon energy range with tunable elliptical polarization. The efficient use of such pulses depends on the specific beamline, should you be interested in these options, please contact the beamline scientist and fermi.usersupport@elettra.eu for more information.

Call for LTP and BAG proposals will be open mid-June 2026.

Deadline will be around 15 July 2026.

The deadline for proposal submission for 2027-I is 1 September 2026, 23:59 (CET).

More information about the proposal submission can be found here.

Deadlines for PETRA III call for regular proposals are usually 1 March and 1 September.

Next Call for Proposals will be issued in Summer 2026.
