Hard X-ray Photoemission Spectroscopy

　A hard X-ray hemispherical electron analyzer of R-4000L1-10kV made by Scienta Omicron, which can analyze up to 10 keV photoelectrons, has been installed in the 2nd experimental hutch. The excitation photon energies for HAXPEX measurements were fixed at 5.95 keV, 7.94 keV, and 9.92 keV using the combination of DCM (Si(111) and CCM(Si(333), Si(444), Si(555)), respectively. The normal HAXPES measurements were performed at 7.94 keV, with good energy bandwidth and X-ray intensity. The incident X-rays were collected using the Rh-coated mirror with a bending system in the horizontal direction and the elliptical mirror in the vertical direction. The Rh-coated mirror can remove the higher-order harmonics. The beam size at the sample position was approximately 250 µm in the horizontal direction and 20 µm in the vertical direction. The SES software (Scienta Omicron) can control a motor controller and a photoelectron measuring system.
