We measured soft X-ray natural circular dichroism (SXNCD) of aspartic acid (Asp) and tyrosine (Tyr) at oxygen K-edge region, in an attempt to obtain chiral structure at the vicinity of oxygen atoms. SXNCD measurement was carried out at the BL25SU beamline of the SPring-8, Japan. We focused on oxygen COO$$^{-}$$ 1s $$pi$$$$^{*}$$ transitions around 533 eV. Since we used sublimation films which are randomly oriented samples, we could reject E1E2 mechanism and pick up only E1M1 mechanism.

First-principle based gyrokinetic turbulent transport simulation with realistic tokamak equilibrium towards ITER and DEMO

Nakata, Motoki; Honda, Mitsuru; Yoshida, Maiko; Urano, Hajime; Maeyama, Shinya; Nunami, Masanori*; Watanabe, Tomohiko*

no journal, , 

First-principle based gyrokinetic simulation is a powerful method for investigating turbulent transport in magnetically confined fusion plasmas, and the quantitative evaluations of the prediction capability through comparisons with existing experiments and the model improvement are important issues. In this study, a local gyrokinetic turbulence code GKV-J is extended to incorporate realistic tokamak equilibria to realize the first principle based turbulent transport simulations on JT-60U tokamak. In addition to clarifications of the micro-stability properties depending on the radial locations, the turbulence simulation results successfully reproduce the experimental results on ion and electron heat diffusivity in the core region, where the conventional fluid-type reduced transport model shows some deviations. Also, the impact of shaping on turbulent transport properties is identified for JT-60SA tokamak.

First-principle based gyrokinetic simulation is a promising approach for investigating turbulent transport in future burning plasmas such as ITER an DEMO. In this study, ITG-TEM driven turbulent transport simulations on the realistic JT-60U tokamak equilibrium are realized by using a local gyrokinetic turbulence code GKV-J. Linear micro-stability analyses on several radial locations revealed that ITG, ITG-TEM, and TEM modes are dominant for inner, middle, and outer core regions, respectively. The nonlinear turbulence simulation results successfully reproduce the experimental results on ion and electron heat diffusivity in the core region, where the conventional fluid-type reduced transport model shows some deviations. Also, different nonlinear dependences of the turbulence/zonal-flow energy on the ion/electron heat and particle transport levels are newly identified, i.e., weaker impact on the electron heat and particle transport compared to the ion heat one.
