AbstractAbstract
[en] The bulk photovoltaic effect that arises in non centrosymmetric crystals is determined by the third rank tensor. In this work four independent components of photovoltaic tensor, responsible for 'linear' photovoltaic currents, are measured for the first time for LiTaO3 : Fe crystals in the range of photon energy from 2.07 to 3.88 eV. The observed correlation of the spectral dependences of β15 and β22 components indicates common origin of the transverse photovoltaic currents in this material

AbstractAbstract
[en] Langmuir probe data obtained from about 290 Ohmic discharges in the Frascati Tokamak (FT) have been analysed in the following ranges of macroscopic plasma parameters: line averaged plasma density n-bare=2.5x1013 to 2.7x1014cm-3, plasma current Ip=230-450 kA, toroidal magnetic field BT=6T and 8T. The principal parameters of the scrape-off layer (SOL) plasma, i.e. the density and the temperature at the limiter radius, neL and TeL, respectively, and their e-folding lengths λn and λT have been obtained and correlated with those of the main plasma. The scaling laws for neL and TeL as a function of the macroscopic plasma parameters are explained only partially with the existing simple diffusion models, which cannot account for the experimentally observed dependence of neL on the safety factor qL. The empirical laws are neL=3.96x10-2n-bare1.38qL and TeL=6.5(Ip/qL)2/3n-bare-0.75, where n-bare and neL are in units of 1013cm-3, Te is in eV and Ip in kA. For λn, the scaling λn=1.05n-bare-0.25cm holds, with the same units. No reliable law is derived for λT, but the approximate relationship λT approx. 2.5-4λn always holds true. The fluctuations in the SOL and their role in determining the perpendicular particle diffusion and, hence, λn are discussed. (author). 17 refs, 8 figs

AbstractAbstract
[en] The ideal rectangular axial structure of the eigenfunction of the curvature driven trapped particle mode, localized in the central cell of a tandem mirror is critically examined and revised. The search for a physical damping mechanism which can truncate the short wavelength part of the spectrum of the ideal eigenfunction has led to the halo coupling of the trapped particle mode. The radial coupling of the trapped particle mode to the halo plasma can excite acoustic modes which are strongly damped at short wavelengths. This mechanism can easily smooth out the ideal rectangular structure. Approximate results indicate a significant departure from the ideal rectangular structure and a corresponding reduction of the growth rate. (author). 6 refs, 2 figs
