Vacuum ultraviolet beam lines at Laboratório Nacional de Luz Síncrotron, the Brazilian synchrotron source

Sem informaçãoA TGM beamline for the spectral range 12-310 eV is being built at Laboratório Nacional de Luz Síncrotron (LNLS). This beam line consists of safety devices, a condensing mirror, a toroidal grating monochromator, and a refocusing mirror. This beam line has been assembled up to the exit slits. A spherical grating monochromator beam line has been designed for the spectral range 200-1000 eV. The performance is limited by the surface slope error in the gratings. If the rms figure error is 2 μrad, the expected resolving power is better than 3000.A TGM beamline for the spectral range 12-310 eV is being built at Laboratório Nacional de Luz Síncrotron (LNLS).
