11/06/2015IDirector: Jose Manuel Donoso Vargas//Participante: Jorge Gonzalez Muoz//HIPER!The High Power laser for Energy Research project (HiPER) was conceived as a large scale laser system designed to demonstrate significant energy production from inertial confinement fusion.
Using a system of high powered lasers as a driver, HiPER encompasses a suite of technical approaches to achieving controlled fusion reactions in pellets of Deuterium/Tritium fuel. The aim is to raise the fusion fuel to a temperature and density sufficient to 'ignite' it, inducing a propagating burn wave within the fuel. This fusion reaction will yield high energy gain from the flux of energetic neutrons released.
The HiPER Facility will rely upon a large number of investigators, postdoctoral researchers and their corresponding student population. Like other international laser facilities HiPER will become a rich source of talent across a range of relevant fields of expertise.
As the Project moves from the concept stage to design, construction and operations, involvement of industry and technology transfer will naturally follow.
In addition to its primary task of fusion energy research, the HiPER facility will enable world class research in a range of associated fields of physics. It will provide a very significant science facility for Europe, supported by a wide range of existing national laser facilities.<Proyectos y convenios en convocatorias pblicas competitivas

The term "gassurface interactions" identifies the ensemble of the physical processes, typically superficial diffusion of mass, momentum, energy and chemical kinetics, that occur at the interfaces between a hightemperature gas mixture and the solid walls bounding the nonequilibrium hypersonic flow of the mixture. The unfortunately unexpected impossibility of implementation in available flow solvers pointed determines the necessity to develop novel numerical algorithms to deal with the novel form of the equations.

tails through an adjustable kappa parameter. The aim of this work is to show
that such a parameter can itself be regarded as a function, which entangles
information about the sources of disequilibrium. We first derive and analyse
an expanded Fermi?Dirac kappa distribution. Later, we use this expanded
form to obtain an explicit analytical expression for the kappa parameter of a
heated metal on which an external electric field is applied. We show that such
a kappa index causes departures from equilibrium depending on the physical
magnitudes. Finally, we study the role of temperature and electric field on
such a parameter, which characterises the electron population of a metal out

A scaleddown hollow cone with gold walls, a carbon tip and a curved hydrogen foil inside the cone has been considered. Proton acceleration is driven by a 10^20 W/cm^2 and 1 ps laser pulse focused on the hydrogen foil. Simulations show an important surface current at the cone walls
which generates a magnetic field. This magnetic field is dragged by the quasineutral plasma formed by fast protons and comoving electrons when they propagate towards the cone tip. As a result, a tens of kT Bz field is set up at the cone tip, which is strong enough to deflect the protons and increase the beam divergence substantially. We propose using heavy materials at the cone tip and increasing the laser intensity in order to mitigate magnetic field generation and proton beam divergence.!Matter and Radiation at Extremes 2468080X10.1016/j.mre.2016.11.0012836ENERO#Autor: Jose Javier Honrubia Checa//Autor: A.

MULTIn
Zpinch dynamic hohlraum can effectively convert Zpinch plasma kinetic energy into radiation field energy, which
has a potential to implode a pellet filled with deuteriumtritium fuel to fusion conditions when the drive current is
sufficiently large. To understand the formation process of Zpinch dynamic hohlraum on JULONGI facility with a typical
drive current of 8?10 MA, a new radiation magnetohydrodynamics code is developed based on the program MULTIIFE.
MULTIIFE is a onedimensional, twotemperature, multigroup, opensource radiation hydrodynamic code, which
is initially designed for laser and heavy ion driven fusion. The original program is upgraded to simulate Zpinch related
experiments by introducing Lorentz force, Joule heating and the evolution of magnetic field into the code. Numerical
results suggest that a shock wave and a thermal wave will be launched when the high speed plasma impacts onto the
foam converter. The thermal wave propagates much faster than shock wave, making the foam become hot prior to the
arrival of shock wave. For the load parameters and drive current of shot 0180, the calculated propagation speed of
thermal wave and shock wave are about 36.1 cm/?s and 17.6 cm/?s, respectively. The shock wave will be reflected when
it arrives at the foam center and the speed of reflected shock wave is about 12.9 cm/?s. Calculations also indicate that
the plastic foam will expand obviously due to the high temperature radiation environment (?30 eV) around it before
the collision between tungsten plasma and foam converter. The evolution of radial radiation temperature profile shows
that a pair of bright strips pointing to the foam center can be observed by an onaxis streak camera and the radiation
temperature in the foam center achieves its highest value when the shock arrives at the axis. A bright emission ring
moving towards the foam center can also be observed by an onaxis Xray frame camera. The best time to capture the
bright strips and bright emission rings is before the thermal wave reaches the foam center. Even though some amount of
Xray radiation in the foam is expected to escape from the hohlraum via radiation transport process, simulation results
suggest that the tungsten plasma can serve as a good hohlraum wall< . The radiation temperature is about 80 eV when
the dynamic hohlraum is created and can rise more than 100 eV before the shock arrives at the foam center. Most of
the Xrays emitted by the wirearray plasma surface have energies below 1000 eV. In this paper, the physical model of
the code MULTIIFE and the simulation results of array implosions on Saturn facility are presented as well.Acta Physica Sinica 100032900,624Vol. 6621215201 Autor: Wu FuYuan //Autor: Chu YanYun //Autor: Ye Fan //Autor: Li ZhengHong //Autor: Yang JianLun //Autor: Wang Zhen //Autor: Qi JianMin //Autor: Zhou Lin //Autor: Liang Chuan //gReinjection Probability Density for TypeIII Intermittency With Noise and Lower Boundary of Reinjection/JOURNAL OF COMPUTATIONAL AND NONLINEAR DYNAMICS 155514231,22310.1115/1.4034732.Autor: sergio elaskar //Autor: andrea costa //Supersonic plasma beams with controlled speed generated by the alternative low power hybrid ion engine (ALPHIE) for space propulsion10.1063/1.50058818sAutor: Luis Conde Lopez//Autor: Juan Luis Domenech Garret//Autor: Jose Manuel Donoso Vargas//Autor: Julius Damba //JAutor: s. p. tierno //Autor: e. alamillogamboa //Autor: m. a. castillo //ISSN o ISBNEntidad relacionadaLugar del congreso0A nonequilibrium approach regarding hot metals &This work discusses about the transport coefficients for non equilibrium hot metals.

the Kappa distribution. Also, we reexamine the connection between a materialdependent coefficient

previous studies by analyzing additional metals used as thermionic emitters. Finally, in the light

BIntegrated simulations of fast ignition of inertial fusion targetsFast ignition of fusion targets is a good example of the multiple time scales found in inertial confinement fusion. Simulations of fast ignition of fusion targets carried out at the MareNostrum and Magerit High Performance Computers of the Spanish Supercomputing Network were presented. They comprise multidimensional radiation hydrodynamics, PIC (ParticleInCell) and hybrid simulations of fast ignition of imploded inertial fusion capsules.mPresentado en 11th RES Users' Meeting & 6th HPC Advisory Council Conference,
Red Espaola de SupercomputacinESPAASantiago de Compostela3Ion driven fast ignition of inertial fusion targetsWe review the standard proton fast ignition (pFI) scheme taking into account i) beam divergence, ii) collective effects due to the selfgenerated resistive fields and iii) an improved model for stopping power. The divergence study is motivated by the important proton beam divergence observed in PIC simulations at the tip of the cone typically used for pFI. Collective effects have been explored because hybrid simulations have shown that resistive fields can affect ion beam propagation from the cone to the core, increasing moderately (?10%) the proton beam ignition energies reported so far. Regarding the stopping power model, recent experiment have shown a good agreement with the BPS stopping model and substantial differences with the standard stopping models. Therefore, as the ranges predicted by the BPS model are 2030% higher, the optimal ion kinetic energies required to obtain the minimum ignition energies should be reduced.
The relevance of the three effects mentioned above will be analysed within the context of pFI. Despite the goal of our study has been to evaluate the minimum ignition energies of pFI, the importance of resistive fields and BPS stopping in high energy density matter generation will be discussed as well.

lossesAn analytical model of a collisional plasma being compressed by a cylindrical liner is
proposed and solved in a magnetized liner inertial fusionlike context. The implosion is
assumed to be isobaric, and the plasma is initially magnetized. The model reduces to a system
of two partial differential equations for temperature and magnetic field. This system is
controlled by the Pclet number, magnetic Reynolds number and the electron Hall parameter.
Depending on their initial value, the imploding plasma tends to either an unmagnetized
diffusive state or a magnetized state. Scaling laws for temperature, magnetic field, hot spot
mass increase and magnetic field losses are obtained. Effects of finite thermal to magnetic
pressure ratio are also considered. Special attention is given to the effect of the Nernst term
on the degradation of the total magnetic flux conservation. It is found that due to the Nernst
term, the magnetic field is advected outwardly and piled up against the liner, enhancing the
diffusion. The magnetic flux losses get independent of the magnetic Reynolds number in a
large Reynolds limit. It is shown how the plasma magnetization reduces the effect of the
Nernst velocity.Pster=Autor: Fco. Javier Sanz Recio//Autor: Fernando Garcia Rubio//Autor: R. Betti //AMass ablation and magnetic flux losses in a plasmawall interfaceMagneto Intertial Fusion (MIF) concepts rely on insulating magnetically the fuel in order to
reduce the electron thermal conductivity and relax the implosion velocity and areal density
requirements [1]. In 2010, Slutz and collaborators [2] proposed a scenario in which a magnetized
cylindrical capsule enclosed by a metallic liner is compressed at 100 km/s by a pulsedpower
machine. The attractiveness of this regime, denoted as Magnetized Liner Inertial Fusion (MagLIF),
resides in the possibility of designing high gain configurations by adding a cryogenic deuteriumtritium
layer in the inner surface of the liner [3].
A key point for MagLIF success is to understand how the magnetic flux losses in the plasmaliner
interface are enhanced by the Nernst term even when the plasma is very conductive [4], and
how magnetization reduces the effect of the Nernst velocity.
In this talk, the evolution of a hot magnetized deuterium plasma in contact with a cold
unmagnetized deuterium wall is analyzed, aiming to represent crudely the plasmaliner interface in
a high gain MagLIF configuration. A fluid model is proposed and the transport terms are taken
from Braginskii [5]. The solution presents a selfsimilar structure, in the form of a diffusive wave,
depending on two parameters solely: the electron hall parameter ? and the magnetic Lewis
number Le, defined as the ratio between thermal and magnetic diffusivities. The wall is treated as
a cold magnetic isolant plasma with zero thermal conductivity. Special attention is paid to the effect
of the Nernst term. Scaling laws for the dependence of mass ablation and magnetic flux losses with
? are analytically derived. Effects of finite thermal to magnetic pressure ratio ?, usually
disregarded in this problem, are taken into account. IFSA 2017 (Saint Malo)http://web.luli.polytechnique.fr/ifsa2017openconf/openconf/modules/request.php?module=oc_program&action=view.php< &id=76&file=1/76.pdf

and experimental consideration. This interaction essentially involves charge emission and collection processes
that may perturb the whole plasma inside a device [1]. A wide range of processes appears when a plasma
interacts with a wall, such as the thermionic emission, discharges, that may govern the plasma dynamics and the
confinement. Many fluid [2] and kinetic [3] models attempt to describe this scenario, accounting for various
phenomena under different time and spatial scales. In this work, some kinetic models to describe the dynamics of
Weakly Ionized Plasmas in front of a metallic flat wall are presented. In these plasmas elastic collisions between
charges and neutrals play a relevant role to properly describe the dynamics of the system [4]. Kinetic
descriptions provide an excellent tool to deal with the processes of disparate intensities, time scales and origin
that appear in the plasmawall system. Phenomena such as the selfconsistent electric field and electric density
currents, or the interaction between charges and neutrals, can be deeply analysed at kinetic scale to determine its
relevance in the system dynamics. It is found that a proper description of this complex system is only possible
with a selfconsistent study that includes significant possible microscopic effects to elucidate and to understand
macroscopic measurable effects.
To solve the proposed models, the Propagator Integral Method [5] is employed. Since this method
provides a physically meaningful time evolving solution, as a semianalytical method, it allows to accounting for
many phenomena of disparate time and spatial scales simultaneously, without affecting the method consistency.

Studies of the stationary plasma expansion process using a fourgrid retarding field energy analyzer (RFEA), an emissive probe (EP) and a Langmuir probe (LP), all mounted on a three dimensionally (3D) displaced multiprobe structure are discussed. Specifically, the determination of plasma beam properties from the RFEA current ?voltage (IV) characteristic curves is presented. The experimental results show the ion energy spectra to be essentially unchanged over 300 mm along the plasmajet expansion axis of symmetry. The measured ion velocity distribution function (IVDF) results from the superposition of different ion groups and has two dominant populations: A lowenergy group constituted of ions from the background plasma is produced by the interaction of the plasma jet with the walls of the vacuum chamber. The fastion population is composed of ions from the plasma beam moving at supersonic speeds with respect to the lowenergy ions. The decreasing spatial profiles of the plasmajet current density are compared with those of the lowenergy ion group, which are not uniform along the axis of symmetry because of the small contributions from other ion populations with intermediate speeds.O12th International Workshop on Electric Probes in Magnetized Plasmas (IWEP2017)Naklo, Eslovenia10711072bBook of abstracts / 12th International Workshop on Electric

Integral Method SolutionsThe comprehension of the phenomena involved in plasma thrusters devices, where ions can be
accelerated to high velocities, is of relevant importance to improve the efficiency and designing of these engines,
as well as to ensure a correct interpretation of plasma diagnostics measurements [1,2]. Usually, fluid model
equations mislead upscaling diffusive kinetic effects that remains to mesoscopic or fluid scales. We present an
extension of the previously stated onedimensional collisional velocityspace kinetic model [3,4], for weakly
ionized plasmas, to describe a plasma plume column in physical space. We propose a slabbing model to compute
the transient ion distribution function by including elastic collisions and chargeexchange contributions. The
plasma is spatially sectioned into a set of contiguous interconnected slabs, transversal to the direction of the
flows carried from the ionization chamber to the exhaust area. For each plasma slab, the kinetic nonlinear
equation is solved by the semianalytical stable Integral Propagator Method, which allows the computation of the
nonlocal energy and mass flows of the analysed plasma species. This firstly offered global kinetic treatment
does not require the local thermodynamic equilibrium hypothesis and it establishes a feasible tool able to detect
and describe phenomena, as the merging of two distinguishable ions populations with high and low energy, in
accordance to several experimental results 10511052\Book of Abstracts 12th International Workshop on Electric Probes in Magnetized Plasmas 2017XAutor: Jose Manuel Donoso Vargas//Autor: Jorge Gonzalez Muoz//Autor: Luis Conde Lopez//MJos Javier Honrubia Checa miembro del Comit Cientfico del 13rd DDFIW 2017NMiembro del Comit Cientfico del 13rd DirectDrive and Fast Ignition Workshop/Responsabilidades en la organizacin de eventosJose Javier Honrubia Checa es miembro del International Access Committee de los lseres VEGA del CLPU de la Universidad de SalamancaEl objetivo del International Access Committee del Centro de Lseres Pulsados (CLPU) de la Universidad de Salamanca es seleccionar los experimentos a realizar con los lseres VEGA.
