1.Introduction In 3rd generation synchrotron radiation (SR), one of the most promising items may be control and characterization of polarization state. In particular, they are a crucial factor to study magnetic properties using the various techniques inscattering, absorption, diffraction and emission experiments. Indeed, low emittance SR such as Spring-8 can efficiently realize this performance...

1 . Introduction Understanding of magnetic property and structure in magnetic materials forms a wide field of research interesting not only from a fundamental point but also from a practical point. Advantages in brilliance and polarization of 3rd generation synchrotron radiation (SR) open out a new field in magnetism differing from neutron magnetic scattering. In particular, this is characteriz...

The distribution of TeV spectral slopes versus redshift for currently known TeV blazars (15 sources with z≤0.21, and one with z>0.25) is essentially a scatter plot with hardly any hint of a global trend. We suggest that this is the outcome of two combined effects of intergalactic γγ absorption, plus an inherent feature of the SSC (synchro-self-Compton) process of blazar emission. First, flux di...

We have observed the Orion Molecular Clouds 2 and 3 (OMC-2 and OMC-3) with the Chandra X-ray Observatory (CXO). The northern part of OMC-3 is found to be particularly rich in new X-ray features; four hard X-ray sources are located in and along the filament of cloud cores. Two sources coincide positionally with the submm-mm dust condensations of MMS 2 and 3 or an outflow radio source VLA 1, whic...

Abstract In the extensive field of X-ray diagnostic techniques, nowadays mostly implemented on synchrotron X-ray sources, the X-ray absorption methods offer a relatively simple tool for structural analysis of materials. The advantage of the methods is the sensitivity to chemical species and the insensitivity to the long-range order. An overview of various detection techniques is given together ...
