In order to deal with the problem of quantitative and consistent evaluation of two-dimensional X-ray detectors at synchrotron beamlines, the methodology for X-ray area detector characterization is reviewed. It is based on the definition of a minimum yet complete set of imaging parameters able to describe any kind of two-dimensional detector regardless of its operating range, field of applicatio...

This paper reports the first results of an on-going project aimed at developing a Web-based CSCW system to support scientific collaboration in experiments with ultra-bright light sources (from UV to X-rays), called the Elettra Virtual Collaboratory, and currently being extensively tested in three real-world experimental stations at the Elettra Synchrotron facility.

enhanced production expected in n'p reactions. Figure 4 indicates the 95%-confidence-level cross-section limit over our mass range. " In summary, we find no evidence for production of narrow pp states produced in &'p b,t"pp. In particular, we are unable to confirm the existence of states at 2.02 and 2.20 GeV jc' reported in v-P —4f'PP. Those states would appear as &5standard-deviation effects i...

A novel approach to extract morphological variables in crystalline polymers from time-resolved SAXS data using the method of correlation and interface distribution functions has been devised. The principle of the calculation is based on two alternative expressions of Porod's law using the form of the interference function. The approach enables the continuous estimate of the Porod constant, and ...

The renormalization of the Minimal Supersymmetric Standard Model is discussed. In particular we focus on the soft-supersymmetry breaking sector of the MSSM and comment on non-renormalization theorems. November 2002 Talk given at the 10th International Conference on Supersymmetry and Unification of Fundamental Interactions, SUSY 2002 (June 17-23, 2002, DESY, Hamburg) On the Renormalization of th...

Along with the development of accelerator technology, synchrotron emittance has continuously decreased. This results in increased brightness, but also causes a heavy heat load on beamline optics. Recently, optical surfaces with 0.1 nm micro-roughness and 0.05 µrad slope error (r.m.s.) have become commercially available and surface distortions due to heat load have become a key factor in determi...

We report on a novel condenser for full-field transmission x-ray microscopes that use synchrotron radiation from an undulator source. The condenser produces a Koehler-like homogeneous intensity distribution in the sample plane and eliminates object illumination problems connected with the high degree of spatial coherence in an undulator beam. The optic consists of a large number of small linear...

the main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. the obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...
