After the confirmation of the generation of the Compton backscattered X-rays with Nd:YAG laser and 150 MeV electron beam pulses at last fiscal year, we make some improvements for increase the generated X-ray flux. As one of them, we are developing the laser pulse compression with the stimulated Brillouin scattering (SBS) to obtain a high peak intensity of the Nd:YAG laser. As the SBS medium, we adopt a liquid fluorocarbon which has well achievements for the pulse compression at ILE at Osaka University. We aim the compressed pulse duration to be less than 1 ns. On this meeting we show the present status of the SBS pulse compression system for the Compton backscattering. In addition, we present the recent result of the Compton backscattering experiment without the laser compression technique.

T-dependence and anisotropy of Knight shift and spin-lattice relaxation time T1 of In-NMR have been determined in heavy fermion superconductor CeIrIn. Knight shift and T1 show a strong anisotropy. Knight shift versus static susceptibility plot is non-linear at low temperatures, indicating that the hyperfine coupling depends on temperature. The origin of hyperfine interaction and anisotropy of spin fluctuations will be discussed.

We performed neutron inelastic scattering experiments in NaFe(CO)(HO) that consists of two-leg spin ladders of Fe
ions. We observed sharp magnetic excitation peaks around 
3.5 meV and 5.3 meV. This result shows that the magnetic excitations originate from almost isolated dimers, indicating that the interaction along the leg direction is negligibly small.

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 %.

We report the plan and current status of development for software used on high-intensity chopper spectrometer, 4SEASONS, and Cold Neutron Disk-Chopper Spectrometer, CNDCS, at Materials and Life Science Facility(MLF), J-PARC. We begin to design software packages based on many required functions for performing experiments and analysis, for example control spectrometer system (data acquisition, devices), suggestion of experiment conditions, visualization and so on. This project progresses with software company. On the other hand, we started to collaborate with Korean group about the development of analysis software for inelastic scattering. In this presentation, we will present the current status and plan for software development including collaboration with Korean group.
