An accelerator based 4th generation source is proposed
to provide the user community with coherent femtosecond
light pulses in the UV to X ray range. The project is based
on a CW 0.7-1 GeV superconducting linac delivering
high charge, subpicosecond, low emittance electron
bunches with high repetition rate. A High Gain Harmonic
Generation setup, seeded with high harmonics in gases,
will cover a spectral range down to 0.8 nm. SASE
Radiation will also be provided down to 5 nm. In
addition, two beam loops are foreseen either to enhance
the energy to 1.4-2 GeV or to increase the beam current in
using the energy recovery technique. They will
accommodate fs synchrotron radiation sources in the IR,
VUV and X ray ranges together with a FEL oscillator in
the 10 nm range. Main features of the project and
scientific goals are given. |
