Anomalous ion heat transport is analyzed.in the T-10 tokamak plasma heated.with electron cyclotron resonance heating(ECRH) in second.harmonic ex.ra-ord.nary mod.. Pred.ctive mod.l.ng with empirical scal.ng for Ohmical heat cond.ctivity shows that in ECRH plasmas the calculated.ion temperature could.be overestimated. so an increase of anomalous ion heat transport is required. To stud. this effect two scans are presented. over the EC resonance position and.over the ECRH power. The EC resonance position varies from the high-field.sid. to the low-field.sid. by variation of the toroid.l magnetic field. The scan over the heating power is presented.with on-ax.s and.mix.d.ECRH regimes. d.scharges with high anomalous ion heat transport are obtained.in all consid.red.regimes. In these d.scharges the power bal.nce ion heat cond.ctivity ex.eed. the neoclassical level by up to 10 times. The high ion heat transport regimes are d.stinguished.by three parameters: the ratio Te/Ti, the normalized.electron d.nsity grad.ent R/■, and.the ion–ion collisionality νii~*. The combination of high Te/Ti, high νii~*, and.R/■=6-10 results in values of normalized.anomalous ion heat flux.s up to 10 times higher than in the low transport scenario.

Mathematical mod.l.ng of the interaction between solar rad.ation and.the Earth's atmosphere is formalized.by the rad.ative transfer equation(RTE), whose resolution calls for two-stream approx.mations among other method.. This paper proposes a new two-stream approx.mation of the RTE with the d.velopment of the phase function and.the intensity into a third.ord.r series of legend.e pol.nomials. This new approach, which ad.s one more term in the ex.ression of the intensity and.the phase function, allows in the cond.tions of a pl.ne parallel atmosphere a new mathematical formulation of γparameters. It is then compared.to the Ed.ington, Hemispheric Constant, Quad.ature, Combined.d.lta Function and.Mod.fied.Ed.ington, and.second.ord.r approx.mation method. with reference to the d.screte Ord.nate(d.sort) method.δ –128 streams), consid.red.as the most precise. This work also d.termines the conversion function of the proposed.new Method.using the fund.mental d.finition of two-stream approx.mation(F-TSA) d.veloped.in a previous work. notably,new Method.has generally better precision compared.to the second.ord.r approx.mation and.Hemispheric Constant method..

In spite of this d.vergence in reflectance for high values of optical thickness, very strong correlation with the d.sort method.R ≈ 1) was obtained.for most cases of optical thickness in this stud.. An analysis of the legend.e pol.nomial series for simple functions shows that the high precision is d.e to the fact that the approx.mated.functions ameliorate the accuracy when the ord.r of approx.mation increases, although it has been proven that there is a limit ord.r d.pend.ng on the function from which the precision is lost.

d.rected.x.rays prod.ced.in the interaction of sub-picosecond.laser pulses of mod.rate relativistic intensity with plasma of near-critical d.nsity are investigated. Synchrotron-like (betatron) rad.ation occurs in the process of d.rect laser acceleration (d.A) of electrons in a relativisticlaser channel when the electrons und.rgo transverse betatron oscillations in self-generated.quasi-static electric and.magnetic field.. In anex.eriment at the PHElIx.laser system, high-current d.rected.beams of d.A electrons with a mean energy ten times higher than the pond.romotive potential and.max.mum energy up to 100 MeV were measured.at 10^(19) W/cm^(2)laser intensity. The spectrum of d.rected.x.raysin the range of 5–60 keV was evaluated.using two sets of Ross filters placed.at 0°and.10°to the laser pulse propagation ax.s. The d.fferential x.ray absorption method.allowed.for absolute measurements of the angular-d.pend.nt photon fluence. We report 10^(13) photons/sr withenergies >5 keV measured.at 0°to the laser ax.s and.a brilliance of 10^(21) photons s^(−1) mm^(−2) mrad.2(0.1%BW)−1. The angular d.stributionof the emission has an FWHM of 14°–16°. Thanks to the ultra-high photon fluence, point-like rad.ation source, and.ultra-short emissiontime, d.A-based.keV backlighters are promising for various applications in high-energy-d.nsity research with kilojoule petawatt-class laserfacilities.
