Session 4: SASE FEL

Contributed Oral Presentation

Standard x-ray free-electron lasers (FELs) generate pulses with total durations of tens of femtoseconds and with time and spectral profiles consisting of multiple randomly distributed spikes. Strongly compressing an electron beam is a typical approach to produce shorter and coherent FEL pulses. We have advanced this method by starting at the injector of the FEL facility with electron beams...

Session 4: SASE FEL

Contributed Oral Presentation

Driven by a continuous-wave superconducting linear accelerator, a high-repetition-rate x-ray FEL has been build at SLAC. After commissioning in 2022 and 2023, early user operation was started in 2024. By the end of 2025, the machine was operated with up to 93,000 Hz beam rate, supporting 3 soft x-ray user stations. We will report the beam and FEL performance, operation observations and...
