法国的第四代光源项目ARC-EN-CIEL(增强型相干强扩展光加速器辐射)是一个独特的设施，为用户社区提供覆盖UV、VUV和软X射线光谱范围的相干飞秒光脉冲。它基于CW 1GeV超导直线加速器，提供高电荷、亚皮秒、低发射度、高重复频率(1 KHz)的电子束，极化可调至1keV。除了以气体中的高次谐波(HHG)为种子的高增益谐波产生(HGHG)实验，允许产生低至0.8 nm的辐射外，在使用能量恢复技术时，预计会有两个束流回路来增加束流。它们将容纳红外、真空紫外线和X射线范围内的飞秒同步辐射源，以及10纳米范围内的自由电子激光振荡器。此外，预计加速器和激光社区之间将产生重要的协同作用。事实上，电子等离子体加速将被测试，硬X射线飞秒辐射将由汤姆森散射产生。该项目的第一阶段，即ARC-EN-CIEL第一阶段，目前正在研究中。我们将给出一个一般性的概述。
The French project of a fourth generation light source, ARC-EN-CIEL (Accelerator-Radiation for Enhanced Coherent Intense Extended Light), is a unique facility providing the user community with coherent femtosecond light pulses covering the UV, VUV and soft X ray spectral range. It is based on a CW 1 GeV superconducting linear accelerator delivering high charge, subpicosecond, low emittance electron bunches with high repetition rate (1 kHz), and adjustable polarisation until 1 keV. In addition to the High Gain Harmonic Generation (HGHG) experiment seeded with High Harmonics in Gases (HHG), allowing radiation down to 0.8 nm to be produced, two beam loops are foreseen 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. Moreover, an important synergy is expected between accelerator and laser communities. Indeed, electron plasma acceleration will be tested and hard X ray femtosecond radiations will be produced by Thomson Scattering. The first phase of the project, ARC-EN-CIEL phase 1, is now under study. A general overview will be given.
