We discuss the design of double plane grating compressors to be used for chirped pulse amplification on free-electron laser (FEL) ultrashort pulses at energies higher than 100 eV. In particular, the design of a grating compressor for wavelength emission centered at 10 nm is demonstrated. The XUV efficiency measurements in the 8-12 nm range of the gratings to be used in a double plane grating compressor realized for an upcoming experiment planned at FERMI is presented and discussed. The overall instrument efficiency is furthermore analyzed.

Abstract
We discuss the design of double plane grating compressors to be used for chirped pulse amplification on free-electron laser (FEL) ultrashort pulses at energies higher than 100 eV. In particular, the design of a grating compressor for wavelength emission centered at 10 nm is demonstrated. The XUV efficiency measurements in the 8-12 nm range of the gratings to be used in a double plane grating compressor realized for an upcoming experiment planned at FERMI is presented and discussed. The overall instrument efficiency is furthermore analyzed.
