Halo background in SLS-FEMTO

15-JUL-2008, 10 pages [PDF]

A proposed upgrade of the laser slicing repetition frequency to increase the flux for FEMTO also increases the background noise of the experiment, because the laser repetition time is much shorter than the radiation damping time, leading to a formation of an equilibrium beam halo. An analytical estimate of the noise to signal ratio as a function of laser repetition rate is derived and compared to an alternative estimate.

Coma-free operation mode of the SAXS spectrometer

5-MAY-2008, 5 pages [PDF]

An operation mode of the SAXES spectrometer identically free of coma aberrations is identified. This mode brings an improvement of resolution by a factor of ~2 compared to operation at arbitrary incidence angles. Moreover, it allows increase of the spectrometer aperture and thus throughput without any significant loss of resolution. A software tool is developed to find the coma-free spectrometer settings.
