The 19th 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 December 1st, 2025 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.

Rapid Acces proposals are a way to obtain free beamtime on decision of the Experimental Division Direction.

Thay are submitted continiously but are limited to a really small number of proposals, only for urgent work.

All ELBE sources including FELBE and TELBE are open to users through an online portal (GATE). There are two calls for Beamtime Proposals per year with deadlines in the spring and in the fall.

The next deadline for the submission of beamtime applications is March 23rd, 2026.

User access to the ELBE - Center for High-power Radiation Sources is managed in line with the recommendations of the European Charter for Access to Research Infrastructures. Beamtime proposals are reviewed by an external science advisory committee. It is quality-based and relies on a peer-review procedure based on research proposals. The primary selection criterion is scientific excellence. Among scientifically equally ranked proposals, priority is given to users from countries without national FEL and from EU-13 states, to PhD students, and to women PIs.

Proposals should be submitted electronically using the portal GATE. The use of the template is mandatory.

ELBE as a whole is operated 24 h, 7 days/week, beamtime is granted in units of 12 hours from 6:00 to 18:00 and from 18:00 to 6:00.
