Synchrotron Mössbauer spectroscopy using high-speed shutters

A new method of performing Mössbauer spectroscopy using a fast shutter in combination with microfocused synchrotron radiation is demonstrated.

Feasibility of in-line instruments for high-resolution inelastic X-ray scattering

The `M⁴ instrument' consisting of a combination of two in-line high-resolution monochromators, focusing mirrors and collimating mirrors is presented as an alternate concept to the use of backreflections for inelastic X-ray scattering instruments. Design choices and performance estimates are discussed.
