Radiation dose assessment in advanced synchrotron radiation facility is challenging due to the complexity and uncertainties of radiation source terms induced by high energy particle accelerator. Shanghai Synchrotron Radiation Facility (SSRF) is the first third-generation synchrotron facility in China, which was completed in 2009. Radiation dose assessment for workers at SSRF Beam lines is highl...

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...

A dosimetric procedure to assure the traceability to the air-kerma standard of the measurements performed in synchrotron radiation beams, was implemented at the “Istituto Nazionale di Metrologia delle Radiazioni Ionizzanti” of ENEA (INMRI-ENEA). To this purpose, absolute air-kerma measurements by the ENEA standard free-air chamber for low energy x-rays have been performed at the SYRMEP (SYnchro...

The list of European synchrotron radiation sources is updated. It shows several new facilities coming into operation, or very close to completion. Their characteristics show the present trends of the community. New projects are announced. The capabilities are extended in the countries already equipped, and new countries are willing to build synchrotron radiation sources. All this confirms the v...

We investigate the possibilities to identify the charge of TeV electrons and PeV nuclei using their synchrotron radiation in the earth’s magnetic field. Characteristics of synchrotron radiation photons are evaluated and methods of detection are discussed. To be published in Nucl. Inst. Meth.

A report on the establishment of the European Synchrotron User Organization (ESUO), a body representing the interests of synchrotron radiation users across Europe.

A novel experimental technique for tandem mass spectrometry and ion spectroscopy of electrosprayed ions using vacuum-ultraviolet (VUV) synchrotron radiation is presented. Photon activation of trapped precursor ions has been performed by coupling a commercial linear quadrupole ion trap (Thermo scientific LTQ XL), equipped with the electrosprayed ions source, to the DESIRS beamline at the SOLEIL ...

Here, we report on a novel experimental apparatus for performing time-resolved soft x-ray absorption spectroscopy in the sub-ns time scale using non-hybrid multi-bunch mode synchrotron radiation. The present setup is based on a variable repetition rate Ti:sapphire laser (pump pulse) synchronized with the ~500 MHz x-ray synchrotron radiation bunches and on a detection system that discriminates a...

We report the detection of linear polarization from Sgr A⋆ at 750, 850, 1350 and 2000μm which confirms the contribution of synchrotron radiation. From the lack of polarization at longer wavelengths it appears to arise in the millimetre/sub-millimetre excess. There are large position angle changes between the millimetre and sub-millimetre results and these are discussed in terms of a polarized d...

Synchrotron radiation has many compelling advantages over conventional radiation sources in the measurement of accurate Bragg diffraction data. The variable photon energy and much higher flux may help to minimize critical systematic effects such as absorption, extinction and anomalous scattering. Based on a survey of selected published results from the last decade, the benefits of using synchro...
