Infrared Edge Radiation Beamline at Aladdin
نویسندگان
چکیده
An infrared beamline has been constructed at the 800 MeV electron storage ring, Aladdin. The beamline is located downstream of a short straight section, where it collects edge radiation produced by electrons exiting and entering the bending magnets at the ends of the straight section. Measurements at wavelengths of 1–5 μm suggest that the edge radiation is brighter than standard synchrotron radiation. When used for Fourier transform infrared (FTIR) microspectroscopy, the signal-to-noise ratio is 20 times that measured with a glower source. Several applications of the beamline are described.

Performance of new infrared beamline U12IR at the National Synchrotron Light Source
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...
متن کاملA SURF beamline for synchrotron source-based absolute radiometry
A new source-based radiometry beamline was recently constructed at the Synchrotron Ultraviolet Radiation Facility (SURF III). The goal of this beamline is to establish a national source standard with a wide spectral range from the far ultraviolet to the infrared by using the calculability of SURF III. The new beamline is a straight-through white-light beamline with few, if any, optical componen...

The beamline BL43IR at SPring-8 has been constructed as a beamline exclusively dedicated to the infrared spectroscopy. The beamline was designed to make use of infrared synchrotron radiation emitted from a bending magnet of 39.3m bending radius with the acceptance angle of 36.5(H) 12.6(V)mrad and to cover a very wide wavelength range from 500 nm (20,000 cm , 2.5 eV) to 100mm (100 cm , 12.5meV)....
متن کاملXMCD under pressure at the Fe K edge on the energy-dispersive beamline of the ESRF.
The present paper demonstrates the feasibility of X-ray absorption spectroscopy (XAS) and X-ray magnetic circular dichroism (XMCD) at high pressure at the Fe K edge on the ID24 energy-dispersive beamline of the ESRF. In 3d transition metals, performing experiments at the hard X-ray K edge rather than at the magnetically interesting soft X-ray L edges represents the only way to access the high-p...
متن کاملSurface science station of the infrared beamline at SPring-8
An experimental station for surface science has been constructed at the infrared beamline (BL43IR) of SPring-8, Japan. The station utilizes synchrotron radiation in the energy range of 100–20000 cm 1 to perform infrared reflection absorption spectroscopy (IRAS) of surfaces. It consists of an experimental section, a preparation chamber, gas handling equipment and a pair of focusing optics. In si...
