SOLEIL prepares for the future with ARC-EN-CIEL (Accelerator-Radiation Complex for Enhanced Coherent Intense Extended Light), a fourth generation light source project combining the ultimate Free Electron Lasers seeded by High Harmonics Generation in Gas in the VUV-soft X ray domain, undulators in spontaneous emission for the hard X ray at 2 GeV and in the VUV and soft X ray at 1 GeV on two ERL loops and a Free Electron Laser oscillation in the Extreme Ultra Violet region.
