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 ...

Occasionally, very strict vibrational requirements are specified for sensitive equipment used in high-tech facilities, such as radar towers and synchrotron facilities. Various external and internal vibration sources such as traffic, indoor pumps and human activities can have appreciable effect on the vibration levels in such facilities [1]. In the present study, the synchrotron research facilit...

The quantitative Rietveld analyses of twenty samples of CAC from four different manufacturers over the world, one synthetic mixture and a NIST standard were performed using synchrotron radiation. As compared with conventional XRD, synchrotron powder diffraction permitted to find new minor phases, improve the characterization of solid solutions of iron rich CAC phases and reduce preferential ori...

The electron beam quality determines the main synchrotron radiation characteristics therefore beam diagnostics is of great importance for synchrotron radiation source performance. The real-time processing of the electron beam parameters is a necessary procedure to optimize the key characteristics of the source using feedback loops. The frequency of electron beam cycling in the synchrotron stora...

The instrumentation and performance of the new infrared beamline U12IR at the National Synchrotron Light Source of Brookhaven National Laboratory is described. This beamline utilizes infrared synchrotron radiation from a bending magnet. A combination of beamline design features and spectroscopic instrumentation allows the facility to reach the extremely low frequency limit of ;2 cm ~i.e., 60 GH...

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...

ANKA is a 2.5 GeV synchrotron light source under construction at the Forschungszentrum Karlsruhe. The facility consists of a 53 MeV microtron, an injection line, a 500 MeV booster synchrotron, and the ejection line. The whole injector is being built as a turn key system by the industry (Danfysik, Denmark). The interface between the injector and the storage ring is the entrance of the injection ...

For the realisation of a highly brilliant photon beam in a third generation synchrotron radiation source such as SPring-8, it is very important to eliminate an orbital vibration of the stored electron beam. In the SPring-8 storage ring, coherent synchrotron oscillation with amplitude of 0.2mmp-p was observed by BPM located in a dispersive section. Since the energy oscillation amplitude is propo...

The recent BeppoSAX observations of the BL Lac objects Mkn 501 and 1ES 2344+514 have shown that the synchrotron spectrum of these objects peaks, in a ν–νFν representation, at energies at or above 100 keV. One can wonder if these are the most extreme examples of hard synchrotron blazars, or if they are the first cases of a more numerous class of sources. Here I propose the existence of a class o...

X-ray coronary angiography is an invaluable tool for the diagnosis of coronary artery disease. However, the use of iodine-based contrast media can be contraindicated for patients who present with chronic renal insufficiency or with severe iodine allergy. These patients could benefit from a reduced contrast agent concentration, possibly achieved through application of a mono-energetic x-ray beam...
