Paper Abstract

A novel diffraction spectroscopic instrument comprising two focusing multilayer mirrors (MMs) at near-normal incidence and a conventional blazed plane grating at grazing incidence has been implemented. A nearly perfect stigmatism and a theoretical resolving power above 6 X 104 are due to the separation of the focusing and dispersing functions. For higher throughput, MMs with nearly identical resonance reflection curves around (lambda) 0 approximately equals 135 angstroms have been synthesized employing a magnetron ion sputtering source. The instrument performance has been assessed using a laser-plasma XUV radiation source. The spectral resolution in excess of 4 X 103 and the applicability to space-resolved spectroscopy and plasma diagnosis have been demonstrated.
