Performance of BL07A at NewSUBARU with installation of a new multi-layered-mirror monochromator

Soft X-rays excite the inner shells of materials more efficiently than any other form light. The investigation synchrotron radiation (SR) processes using inner-shell excitation requires beamline to supply a single-color and high-photon-flux light in soft X-ray region. A new integrated computing multi-layered-mirror (MLM) monochromator was installed at 07A (BL07A) NewSUBARU, which has 3 m undulator as source for irradiation experiments with monochromatic MLM high reflectivity index region; it eliminates unnecessary harmonic from lowers temperature irradiated sample surfaces. can be operated vacuum, three different mirror pairs are available experimental energy ranges; they exchanged without exposing atmosphere. Measurements photon current photodiode on stage indicated that flux beam 10 14 photons s −1 cm −2 range 80–400 eV 13 400–800 eV. Thus, BL07A is capable performing SR-stimulated process experiments.
