Goerigk, G.; Varga, Z.: Comprehensive upgrade of the high-resolution small-angle neutron scattering instrument KWS-3 at FRM II. Journal of Applied Crystallography 44 (2011), p. 337-342
After moving from Jülich to Munich (1st half 2007) the instrument underwent a fundamental evaluation with the final result, that a major upgrade for the whole instrument became necessary. The main topic of the upgrade project was a general mirror refurbishment i.e. a new polishing and subsequently a new coating of the mirror surface with the isotope 65Cu. In parallel to the mirror refurbishment comprehensive upgrade activities in the vacuum system, electronics and programming have been performed with the aims of protecting the new mirror coating from aging (degradation of the mirror’s surface properties), transforming the instrument into a user-friendly state and introducing conceptual improvements.
