Samuel Barber (Lawrence Berkeley National Laboratory)19/08/2024, 09:00First LasingInvited Oral Presentation
Compact free electron laser (FEL) technology enabled by plasma-based accelerators is a rapidly maturing technology with several milestone demonstrations in the last several years. Still, critical work is needed to bridge the gap from proof of concept experiments to reliable operation of laser plasma accelerator (LPA) driven FELs. At the BELLA Center, we have a dedicated facility equipped with...

Shaukat Khan (TU Dortmund University)19/08/2024, 09:10First LasingInvited Oral Presentation
Echo-enabled harmonic generation (EEHG) has been proposed as a seeding method for free-electron lasers but can also be employed to generate ultrashort radiation pulses at electron storage rings. With a twofold laser-electron interaction in two undulators (the modulators), each followed by a magnetic chicane, an electron phase space structure with a high harmonic content is produced, which...

This talk presents the recent progress and operation status of the PAL-XFEL, focusing on the accelerator and beamline performance, along with recent developments. The facility is now accommodating approximately 70 user experiments annually. Significant efforts to improve FEL (Free Electron Laser) intensity have successfully increased pulse energies to over 2 mJ in SASE mode and 1 mJ in...

The COXINEL line has been designed at Synchrotron SOLEIL for electron beam manipulation in view of a seeded free electron laser using Laser plasma acceleration (LPA). After first studies on electron beam transport and undulator radiation in the spontaneous emission regime using LPA from Laboratoire d’Optique Appliquée (Ecole Polytechnique, France), the line has been moved to the HZDR,...

has been in operation since 2017. It features a superconducting linear accelerator capable of achieving a maximum energy of 17.5 GeV. The accelerator can deliver up to 27,000 electron bunches per second, distributed into ten equidistant short bursts, each lasting 600 microseconds. It simultaneously serves three FEL undulators, covering photon energy ranges from 300 eV to 30 keV, with pulse...

David Dunning (Science and Technology Facilities Council)19/08/2024, 10:20New FEL projects and Facility ReportsInvited Oral Presentation
The UK is conducting a multi-stage project to analyse the case for major investment into XFELs, through either developing its own facility or by investing at existing machines. The project’s 2020 Science Case identified a clear need for ‘next-generation’ XFEL capabilities including near-transform limited x-ray pulses across a wide range of photon energies and pulse durations; evenly spaced...

Chao Feng (Shanghai Advanced Research Institute)19/08/2024, 10:30New FEL projects and Facility ReportsInvited Oral Presentation
The Shanghai Soft X-ray Free-Electron Laser (SXFEL) facility is the first X-ray FEL facility in China, completed in 2022 and officially opened for operation in 2023. It is based on a 1.5 GeV normal conducting high gradient C-band linac and currently contains two FEL beamlines and five experimental stations. The SXFEL can cover the whole water window range with the shortest wavelength of 2 nm....

Dr Luca Giannessi (Istituto Nazionale di Fisica Nucleare)19/08/2024, 11:10New FEL projects and Facility ReportsInvited Oral Presentation
FERMI was built as a facility using high-gain harmonic generation to provide coherent light down to the soft X-ray region of the spectrum. After some fourteen years of operation, a number of possibilities have been exploited that go beyond the simple control of the spectral quality of the emitted pulses. In fact, the seed has offered the possibility to control pulse duration and phase,...

At NCBJ in Otwock-Świerk a THz facility is under construction. It will deliver THz radiation in the frequency range from 0.5THz to 5THz (600μm - 60μm). Its superconducting cw-operating linac will provide electron bunches at energy up to 60 MeV and charge in the range of 20pC–250pC. In the first stage, electron bunches will be generated in a room temperature electron gun. For the second stage,...

The FLASH facility is driven by a superconducting linac producing 5000 electron bunches per second (1 MHz burst @ 10 Hz) at a max. electron beam energy of 1.35 GeV. The bunches can be distributed between 2 FEL beamlines and a dedicated beamline for beam driven plasma acceleration research. With more than 8000 h of beam operation, of which roughly 4500 h are dedicated to user experiments, FLASH...

Weiqing Zhang (Dalian Institute of Chemical Physics)19/08/2024, 12:30New FEL projects and Facility ReportsInvited Oral Presentation
Since FLASH first lasing at 2005, Free Electron Laser (FEL) has been proved a unique and essential EUV and X-ray source for basic research. However FEL could not serve as many users as Synchrotron Radiation source limited by total user beam time due to linear accelerator (LINAC) instead of storage ring. High repetition rate electron LINAC using superconducting cavity could increase the...
