The ARC-EN-CIEL (Accelerator-Radiation for Enhanced Coherent Intense Extended Light) project proposes a suit of novel light sources for the scientific community. Three FEL sources (LEL1, LEL2 and LEL4) sources rely on High Gain Harmonic Generation (HGHG) radiation and their Non Linear Harmonics seeded with the High Order Harmonics generated in Gas (HHG). LEL1 will cover the 200-1.5 nm spectral range with 100-30 fs FWHM pulses at a few kHz and adjustable in polarisation. LEL2 will provide 10-0.6 nm radiation with planar polarisation, in 100-30 fs pulses at a few kHz repetition rate. LEL4 will cover the 2-0.2 nm range, with 50-30 fs pulses at 1 kHz. LEL3 is a FEL oscillator in the 40-8 nm range with a repetition rate of 4.5 MHz. These FEL sources will reach MW to GW of peak power. In addition, undulator radiation will provide 200 fs pulses with energies up to 20 keV. FEL calculations are presented. The ARC-EN-CIEL project is phased according to the required electron beam energy: in phase 1 (220 MeV), the radiation extends down to 30 nm; in phase 1′ (800 MeV) and phase 2 (1 GeV), the radiation reaches 1 nm. Phase 3 adds LEL3 and the Energy Recovery Linac loops at 1 GeV and 2 GeV, where undulators emit conventional synchrotron radiation above 20 keV from short period in vacuum undulators and soft-X rays are produced from variable polarisation undulators. The accelerator is based on superconducting technology to enable a high repetition rate. The use of plasma acceleration in the project is under investigation.
