A synchrotron radiation beamline in the photon energy range of 18 -240 eV and an electron spectroscopy end station have been constructed at the 3 GeV Diamond Light Source storage ring. The instrument features a variable polarisation undulator, a high resolution monochromator, a re-focussing system to form a beam spot of 50x50 µm 2 and an end station for angle-resolved photoelectron spectroscopy (ARPES) including a 6-degrees-of-freedom cryogenic sample manipulator. The beamline design and its performance allow for a highly productive and precise use of the ARPES technique at an energy resolution of 10 -15 meV for fast k-space mapping studies with a photon flux up to 2 • 10 13 ph/sec and well below 3 meV for high resolution spectra.

“…For high energy xray applications, there is a unique opportunity to use an asymmetrically cut crystal as an ultra-high density grating [15][16][17]. Unfortunately, it is difficult, if not impossible, to find a crystal with a lattice constant, large enough for soft x-ray applications [18].…”

Abstract. We describe a revolutionary new approach to high spectral resolution soft x-ray optics. Conventionally in the soft x-ray energy range, high spectral resolution is obtained by use of a relatively low line density grating operated in 1 st order with small slits. This severely limits throughput. This limitation can be removed by use of a grating either in very high order, or with very high line density, if one can maintain high diffraction efficiency. We have developed a new technology for achieving both of these goals which should allow high throughput spectroscopy, at resolving powers of up to 10 6 at 1 keV. Such optics should provide a revolutionary advance for high resolution lifetime free spectroscopy, such as RIXS, and for pulse compression of chirped beams. We report recent developmental fabrication and characterization of a prototype grating optimized for 14.2 nm EUV light. The prototype grating with a 200 nm period of the blazed grating substrate coated with 20 Mo/Si bilayers with a period of 7.1 nm demonstrates good dispersion in the third order (effective groove density of 15,000 lines per mm) with a diffraction efficiency of more than 33%.

“…The cylindrical M2 mirror will be bendable to compensate the fixed magnification of the grating. Plane grating monochromators (PGM) have the advantage of covering a wide energy range with a single grating [145]. A spectral resolution of 2.5 eV is calculated at 1450 eV (Al K edge) with a 70 µm slit at the intermediate focus.…”
