With numerical simulations and laser-driven experiments we show prospects for the Laser-driven Exotic Nuclei extraction-acceleration method proposed in [M. Nishiuchi et al., Phys. Plasmas 22, 033107 (2015)]: a femtosecond petawatt laser, irradiating a target bombarded by an external ion beam, extracts from the target and accelerates to few GeV highly charged short-lived heavy exotic nuclei created in the target via nuclear reactions.

Times Cited Count:133 Percentile:95.68(Physics, Fluids & Plasmas)The plasma particle interaction with a relativistically intense electromagnetic wave under the conditions when the radiation reaction effects are dominant is considered. We consider the short electromagnetic pulse emission during laser-cluster interaction and the ion acceleration due to the radiation pressure action on a thin plasma slab. A method to generate ultrahigh intense electromagnetic fields is suggested, based on the laser pulse compression, carrier frequency up-shifting and focusing by a counter-propagating breaking plasma wave, relativistic flying parabolic mirror.

Deriving the distribution function requires to know the composition and spatial distribution of the target ions in a plasma. A charge-exchange target forms as a result of the interaction between impurity nuclei and beam atoms. Depending on the arrangement of heating beams with respect to the diagnostics, it is necessary to calculate their trajectories. A model which takes into account elementary processes resulting in the ionization equilibrium of the ions of impurities in a specific tokamak configuration is proposed. The model is applied to the JT-60U plasma. Mechanisms for the formation of charge-exchange atomic flows are considered. The relative contributions of different heating injectors to the charge-exchange flow are estimated. Based on the calculated results, a method is proposed for local measurements of the ion distribution function with a stationary analyzer.

Times Cited Count:51 Percentile:81.60(Physics, Fluids & Plasmas)With the use of the 2D PIC simulations it is demonstrated the regimes of the interaction of the high intensity laser radiation with plasmas when the energy of fast ions is well above the electron energy. This phenomenon is explained within the framework of the theoretical model, which describes the ion motion in the electric field formed inside relativistic electron cloud expanding into a vacuum under the conditions of strong electric charge separation. The upper limit on the maximal energy of fast ions accelerated at the front of the relativistic electron cloud is found.

Times Cited Count:2 Percentile:5.91(Physics, Fluids & Plasmas)The problem of drift stabilization of internal resistive-wall modes (RWMs) in tokamaks is theoretically investigated. The basic assumption of our model is that these modes are unstable in the absence of a conducting wall and stable in the presence of a close-fitting ideally conducting wall, when drift effects are neglected. Stability of the internal RWMs, was estimated for several existing tokamaks contributing to the ITER data base, namely, AUG (ASDEX-Upgrade), DIII-D, JET, TFTR and JT-60U, as well as for the projected ITER-FEAT. It is concluded that although drift effects do not stabilize the internal RWMs in current devices, they should be effective for suppressing these modes in reactor-grade tokamaks.
