GasPhase/Photoluminescence

The HF-CGM high flux and high resolution beamline covers photon energies from 4 to 40 eV. This beamline, which collects 50 mrad of the horizontal radiation, uses a six-meter cylindrical grating monochromator (6m-CGM) with an incident angle of 70 degree instead of the conventional normal incidence monochromator (NIM) design. Special features, such as movable entrance slit, and movable curved exit slit, are employed to enhance greatly the beamline performance. With both slit openings set at 10 µm, the energy resolving power can reach as high as 45000. Photon fluxes of 10¹³ and 10¹⁰ photons/sec are expected for energy resolving power of 1000 and 40000, respectively. The image size at sample position is smaller than 0.45 mm X 0.2 mm.
