INTRODUCTION Synchrotron radiation facilities are to get high brilliance and high power density of synchrotron radiation. Especially, the third generation synchrotron radiation facilities such as the European Synchrotron Radiation Facility (ESRF)(1), The Advanced Photon Source (APS)(2), and SPring-8(3) can get extremely high brilliance, high power density, and high energy photons. The shields o...

We summarize the results of BeppoSAX ToO observation of blazars that were known to be in a high state from observations carried out in the optical or X-ray or TeV bands. In some of the sources observed, two spectral components were detected, which are interpreted as synchrotron and inverse Compton emission, respectively. Fast variability was detected in three sources (ON231, BLLac and S5 0716+7...

IKNO (Innovation and KNOwledge) is a proposal for a multi-user facility based on an electron storage ring optimized for the generation of coherent synchrotron radiation (CSR) in the terahertz frequency range, and of broadband incoherent synchrotron radiation ranging from the IR to the VUV. IKNO can be operated in an ultra-stable CSR mode with photon flux in the terahertz frequency region up to ...

Soft cyclo-synchrotron photons produced by thermal electrons moving in a magnetic eld can be subsequently Comptonized to produce hard X-ray and -ray emission. An accurate determination of the amount of soft cyclo-synchrotron photons produced from such plasmas is clearly necessary. We present the complete solution to the cyclo-synchrotron problem. We calculate the emission produced by an isotrop...

We consider in this paper the effect of synchrotron self-Compton process on X-ray afterglows of gamma-ray bursts. We find that for a wide range of parameter values, especially for the standard values which imply the energy in the electrons behind the afterglow shock is tens times as that in the magnetic field, the electron cooling is dominated by Compton cooling rather than synchrotron one. Thi...

Hard x rays from a synchrotron source are used in this implementation of computed laminography for three-dimensional (3D) imaging of flat, laterally extended objects. Due to outstanding properties of synchrotron light, high spatial resolution down to the micrometer scale can be attained, even for specimens having lateral dimensions of several decimeters. Operating either with a monochromatic or...

We model multiwavelength afterglow data from the short gamma-ray burst (GRB) 090510 using a combined leptonic–hadronic model of synchrotron radiation from an adiabatic blast wave. High-energy, !100 MeV, emission in our model is dominated by proton-synchrotron radiation, while electron-synchrotron radiation dominates in the X-ray and ultraviolet wavelengths. The collimation-corrected GRB energy,...

A prediction for the energy shift of the synchrotron spectrum of flat-spectrum radio quasars (FSRQs) during high-energy flares is presented. If the γ-ray emission of FSRQs is produced by Comptonization of external radiation, then the peak of the synchrotron spectrum is predicted to move to lower energies in the flare state. This is opposite to the well-known broadband spectral behavior of high-...

A small 2.2 Tesla-meter booster synchrotron is under construction at the Indiana University Cyclotron Facility to boost polarized beam performance in the electron cooled Indiana University Cooler Synchrotron. Polarized light proton or deuteron beam from a high intensity polarized ion source will be preaccelerated to 7 and 6 MeV respectively by an RFQ/DTL accelerator. The beams are then debunche...

Since synchrotron radiation was discovered, advanced synchrotron radiation based bioanalytical techniques have been rapidly developed such as synchrotron radiation based soft x-ray (SR-XMS) and synchrotron-based Fourier transform infrared microspectroscopy (SR-IMS). In this article, recently obtained information on potential applications of these bioanalytical techniques (SR-XMS & SR-IMS) was r...
