Infrared beamline BL43IR at SPring-8: design and commissioning

Abstract 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 39.3 m bending radius with the acceptance angle of 36.5( H )×12.6( V ) mrad 2 and to cover a very wide wavelength range from 500 nm (20,000 cm −1 , 2.5 eV) to 100 μm (100 cm −1 , 12.5 meV). A Fourier transform interferometer and four experimental stations were installed to utilize the infrared synchrotron radiation at SPring-8.
