| Abstract: | A novel application of a free-standing transmission grating as a beam splitter in a Michelson-type interferometer is described.
The arrangement can operate in the XUV and soft X-ray spectral region and, therefore, it is well suited for the characterization
of attosecond pulses. Using ray-tracing codes, we have analyzed three different setups in which spherical mirrors are employed
in conjunction with the transmission grating and have investigated in detail their dispersive characteristics. It is shown
that such an arrangement can be made to exhibit group-delay dispersion of ∼1 as2 while it provides two co-propagating and converging beams.
