The photon beam transport and diagnostics system at FERMI@Elettra, the Italian seeded FEL source: commissioning experience and most recent results

摘要

FERMI@Elettra, the Italian Free Electron Laser (FEL) source, is in an advanced commissioning phase, having already delivered radiation down to the endstations. The facility is routinely using the low energy branch (FEL1) to produce photons in the 65–20 nm range, while the 20–4 nm range will be covered by FEL2 that is now being commissioned. A dedicated system to collect, diagnose, transport and focus the radiation (PADReS) is used to provide informations about the photon beam intensity, position, spectral content, transverse coherence, and so on. The experience gathered so far, as well as the most recent results both from the diagnostic section and thebeam manipulation part are presented here.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
