Studies of the damage of biomolecule by the X-ray free electron laser (XFEL) is important to achieve the structure analysis of the single biomolecule. We simulate the electron dynamics after the inner shell vacancy by the XFEL employing the time-dependent density-functional theory (TDDFT). We found the intense electron dynamics after the inner shell vacancy creation and that the electron dynamics enhances the shake-off probability strongly.

Long-lived, highly-excited neutral hydrogen atoms are produced near the O 1s edge of the water molecule. This metastable yield has been studied, along with the kinetic energy of the particles. The excited particles also can decay via fluorescence to the ground state, and by lifetime-resolved detection of the fluorescence new information on the dissociation dynamics can be obtained.

The stability and collimatability of quasi-monoenergetic electron beam production in the self-injected laser-plasma acceleration regime are studied. The collimation of electron beam drived by terawatt femtosecond laser (4.5 TW, 40 fs) is measured at two species of gas material (Helium gasjet and Argon gasjet). We measured 3.2 mrad pointing stability and beam divergence of 11 mrad (r.m.s.) at Argon gasjet for 50 continuous shots. At such condition, the peak electron energy is 9.11.6 MeV. For Helium, the pointing stability is three times larger than that of Argon. It is considered that the laser channel formation is important role for stable electron beam generation.

GeCoO has the spinel structure, in which the Co moments with =3/2 are located at the corners of the tetrahedron. It shows an antiferromagnetic ordering with a characteristic wave vector of =(1/2, 1/2, 1/2) below 21 K accompanied by a structural phase transition from cubic to tetragonal symmetry. This compound also exhibits a magnetic phase transition at 4 T. Magnetic field dependence of some magnetic Bragg peak intensities was measured. For example, the (1/2, 1/2, 1/2) Bragg intensity increases with increasing magnetic field up to 4 T and gradually decreases above 4 T. This characteristic field is consistent with Hc. The field dependence of the intensity probably originates from the combined effects of the redistribution of the magnetic domains and a magnetic phase transition.

In the lower-hybrid current drive experiment for aiming the stationary operation in tokamaks another improved confinement mode to be suppressed the anomalous transport were observed in JT-60, TRIUM-1M and so on. In JT-60, the lower-hybrid current drive experiment by injecting two waves having different frequency the improved confinement like the H mode was found with extremely lower threshold power and in the JT-60U the more efficient electron heating in the core plasma region was found at the negative shear current profile with extremely lower injected power. Considering the physical mechanism of these improved confinement modes of the lower-hybrid current drive experiment some simple calculations are performed to be compared for the experimental results.
