Spatial Coherency of the Synchrotron Radiation at the Visible Light Region and Its Application for the Electron Beam Profile Measurement
نویسنده
چکیده
A spatial coherenceies of SR beam at visible light region were measured both σ and π-polarized components at Photon Factory. A wave-front division type polarized interferometer was designed and constructed for this experiment. Interferograms were observed clearly in the vertical direction. π phase difference of the interference fringe was observed between interferograms corresponding to σ and π-polarized components. Degree of spatial coherence was measured and by means of the van CitterutZernike's theorem, a vertical beam profile was obtained by the Fourier transform of the degree of spatial coherence.

متن کاملImpact of region of interest size and location in Gafchromic film dosimetry
Introduction: Accurate film dosimetry requires careful consideration of sources of uncertainty. Some of the sources of uncertainty are dependent on the size and location of region of interest (ROI), especially in small fields. Avoiding the penumbra is often a reason for using a small ROI. In contrast, choosing very small ROIs may increase uncertainty due to the reduction of th...

In this work, Co3O4 nanorods were successfully prepared by microwave-assisted solid state decomposition of rod-like CoC2O4.2H2O precursor within a very short reaction time (6 min) without the use of a solvent/surfactant and complicated equipment. The as-obtained Co3O4 nanorods were fully characterized by X-ray diffract...
