In intense laser fields, molecules are decomposed into fragments through a number of competing dissociative ionization pathways. We investigate the dissociative ionization dynamics of ethanol in intense laser fields with photoelectron-photoion coincidence momentum imaging. The channel-specific photoelectron spectra reveal the electronic states prepared just after ionization, depending both on the decomposition pathways and on the temporal profile of laser pulses.

The S=1/2 distorted diamond chain is investigated by the density matrix renormalization group and the numerical exact diagonalization. We found that an incommensurate long-range order is induced by the external magnetic field above the 1/3 magnetization plateau. We using this result theoretically explain the field induced incommensurate order observed in the azurite.

Local structure analysis of 0.75BiFeO-0.25BaTiO solid solution was carried out by a synchrotron radiation X-ray pair-distribution function (PDF) method with the temperature range from room temperature to 900
C. The 0.75BiFeO-0.25BaTiO occurred two phase transitions. The average structure of changed from low-temperature rhombohedral structure to pseudo-cubic structure at 500C, but the local structure unchanged. The local structure changed at second phase transition from pseudo cubic structure to cubic structure at 800
C. The local structure of the pseudo-cubic phase can be reproduced not by the average cubic structure but by the distorted rhombohedral structure.

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.

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 %.

The technology of laser optical guiding is important for the laser plasma electron acceleration in order to improve electron beams's energy gain, because the duration of laser focusing represents the length of the laser wakefield. In present, capillary discharge is promising to generate a plasma channel for a laser pulse. Plasma channel in the capillary has a refraction structure in the radial direction to guide a laser pulse, In addition, it is possible to generate a cm-scale plasma, and therefore, the length of the laser wakefield is significantly extended. In this presentation, we reports the investigation of the ablative capillary. The profile measurement and analysis result are presented.
