We have performed synchrotron radiation photoemission study on UFeGa$$_5$$, UB$$_2$$, UPd$$_3$$, UPd$$_2$$Al$$_3$$, UNi$$_2$$Al$$_3$$, URu$$_2$$Si$$_2$$, UPt$$_3$$, UGe$$_2$$, UIr, UPtGa$$_5$$, USb$$_2$$, and UN. Their electronic structures are discussed based on their valence band and core-level photoelectron spectra.

Software development for neutron experimental instruments at MLF, J-PARC

Nakatani, Takeshi; Inamura, Yasuhiro; Ito, Takayoshi; Kajimoto, Ryoichi; Aoyagi, Tetsuo; Ohara, Takashi; Otomo, Toshiya*; Yasu, Yoshiji*; Suzuki, Jiro*; Morishima, Takahiro*; et al.

We have started the commissioning of the neutron scattering experiment instruments since May 2008 in MLF, J-PARC. Simultaneously, we have started the commissioning of the data acquisition and analysis software. Experimental users operate this software through the software framework which we have developed. The software framework was developed based on Python which is an object oriented script language. The system implemented with the software framework can seamlessly measure, analyze and visualize with some modules which are experimental control and data analysis. In this presentation, we report the process of the construction and the current status of the software.

Control of aberrations in acceleration lens system to form gaseous ion nanobeam

Okubo, Takeru; Ishii, Yasuyuki

no journal, , 

Chromatic and spherical aberrations are hindrance in a development of acceleration lens system to form the nanobeam with 1 MeV ion beam. However, chromatic and spherical aberrations are hindrance to form the nanobeam. Optics simulations were carried out to show that a combination of acceleration lenses and deceleration lenses is effective to reduce chromatic and spherical aberrations in the acceleration lens system. As a result, the deceleration energy of 15 keV for the 46 keV hydrogen molecule ion beam enabled us to reduce the chromatic aberration coefficient by 26 % and the spherical aberration coefficient by 17 %, and the beam current increased by 27 %.
