XFEL Main Components 2
Anders Madsen, European XFEL
electron energy~1 – 20 GeV
photon energy0.01 – 25 keV
low emittance electron gun high energy electron accelerator (~2000m) SASE Undulators (~100-200m) photon beamlines and instruments (~1000m)
3SASE X-ray FEL RadiationFEL idea: line up electrons by interaction with x-ray field. This micro-bunching of the electron beam can happen when he undulator
is very long
Spontaneous radiation Coherent radiation
dE = -e vx(t) Ex(t) dtphase Ex(t), vx(t) const. ⇒ acceleration & deceleration
