Times Cited Count：3 Percentile：13.2(Physics, Fluids & Plasmas)A burning plasma simulation scheme has been developed with consideration for temperature dependence of the DT fusion reaction rate in JT-60U. The heating power for the simulation of alpha particle heating was calculated using real-time measurements of density and ion temperature. Response of a simulated fusion gain to the density was investigated in this scheme with constant heating power for the simulation of external heating, in order to understand burn controllability by the fuel density in a fusion reactor. When temperature dependence of the fusion reaction rate was assumed as square of ion temperature, density dependence of the simulated fusion gain stronger than square of density was observed. Transport analysis using a 1.5 dimension transport code indicated that the strong density dependence is induced due to both change in a confinement improvement factor and change in a pressure profile.

Hyperon-nucleon scattering experiment is one of the powerful methods for studying YN interaction. However, it is difficult due to short lifetime of hyperon. 
scattering experiments were performed as KEK E251 and KEK E289 in order to measure the differential cross sections. In these experiments, statistics were limited to less than 100 events and differential cross section had too large statistical errors to restrict baryon-baryon interaction models. J-PARC E40 experiment aims for measuring cross sections of 
scatterings with high statistics (
10000 events) by overcoming difficulties of hyperon-nucleon scattering experiment. By using high rate (
19M /spill) 
beam and large acceptance spectrometer, we can produce and tag large amount of 
beam. LH
target and surrounding detector system CATCH enable us to reconstruct reactions from two body kinematics. Our experimental group completed 
data taking and about half of 
data taking by 2019 Apr. Left data taking will be performed in the end of this fiscal year.

Various physical and mechanical tests were performed on shallow borehole cores ( 30 m) taken from the activated Shionohira and the non-activated Kuruma faults associated with the April 2011 Fukushima-ken Hamadori earthquake. The results showed (1) low strength constants and elastic constants for the fault damage zone samples compared to the host rocks; (2) different physical properties for fault gouge, fault breccia, and Cataclasite of the fault damage zone; and (3) for fault gouge, the importance of considering the stress factor on the fault plane. Data accumulation from various fault damage zones is needed to gain better understanding of the physical properties of the fault damage zone.
