After decades of supremacy of the Titanium:Sapphire technology, Ytterbium-based high-order harmonic sources are emerging as a promising alternative for experiments requiring high flux of ultrashort extreme ultraviolet (XUV) radiation. In this article we describe a versatile experimental setup delivering XUV photons in the 10–50 eV range. The use of cascaded high-order harmonic generation enables us to reach 1.9 mW of average power at 18 eV. Several spectral selection schemes are presented, to isolate a single high-harmonic or a group of them. In the perspective of circular dichroism experiments, we produce highly elliptical XUV radiation using resonant elliptical high-harmonic generation, and circularly polarized XUV by bichromatic bicircular high-harmonic generation. As an illustration of the capacities of the beamline, we focus the XUV beam in a coincidence electron–ion imaging spectrometer, where we measure the photoelectron momentum angular distributions of xenon monomers and dimers.

在钛：蓝宝石技术占据上风的数十年之后，基于Y的高阶谐波源正在成为需要高通量超短极紫外（XUV）辐射的实验的有希望的替代方法。在本文中，我们描述了一种通用的实验装置，可提供10–50 eV范围的XUV光子。级联高阶谐波的产生使我们能够在18 eV时达到1.9 mW的平均功率。提出了几种频谱选择方案，以隔离单个高谐波或一组谐波。从圆二色性实验的角度来看，我们使用共振椭圆高谐波生成来产生高椭圆XUV辐射，并通过双色双圆高谐波生成来产生圆偏振XUV。为了说明光束线的能力，
