New developments in photon diagnostics and optics

Oral presentation

We report on the development of an accurate and flexible concept to compensate for two-dimensional slope errors of mirrors or reflective gratings as used in wavelength-dispersive soft X-ray spectroscopy. Our approach enables an ultra-high spectral resolving power with low-cost optical components [1].

Modern soft X-ray spectrometers often use a toroidal mirror in combination with a variable...

New developments in photon diagnostics and optics

Oral presentation

Measurements of the dynamics of a material on the fs-to-ns temporal scale and atomic length scale provide essential information to guide our understanding of disordered materials. Split-pulse x-ray photon correlation spectroscopy (spXPCS) was recognized early in the development of the Linac Coherent Light Source as a technique that could possibly provide critical measurements of these...
