TīmeklisLaser Technology and Optics (Innovative lasing schemes) We demonstrated high-gain EEHG lasing producing stable, intense, nearly fully coherent pulses at wavelengths as short as 5.9 nm (211 eV) at the FERMI FEL. Observation of stable, narrow-band, coherent emission down to 2.6 nm (~474 eV) make the technique a prime candidate … TīmeklisFERMI is the seeded FEL user facility in Trieste, Italy, producing photons from the VUV to the soft X-rays with a high degree of coherence and spectral stability. Both FEL lines, FEL-1 and...

Tīmeklis2015. gada 6. janv. · FERMI FEL sketch including the 3-m-long modulator (planar undulator with a period of 100.3 mm), the dispersive section (three-pole wiggler with an overall length of 700 mm) and six 2.3 m long radiators (Apple II undulator, with a period of 55.2 mm and tunable both in linear and in circular polarization). Reuse & Permissions TīmeklisThe FERMI FEL-1 radiator (RAD) is composed of 6 undulators , each 2.4 meter long , with a period of 55 mm. FERMI Parameters In the present experiments FERMI uses electron beams accelerated by a normal conducting linear accelerator to a final energy of about 1.2 GeV . Tīmeklis2010. gada 6. jūl. · FERMI will provide the first experimental test of a multiple harmonic upshift approach to short wavelength generation. If successful, future FEL facilities seeded by coherent high harmonic generation (HHG) sources can apply this approach to reach sub-nm output wavelengths. Figure.
