Artep Awarded multi year contract for continued support of NRL’s Plasma Physics Division.
As a follow on to the previous research contract with Plasma Physics (Analysis of the interaction of radiation with non-LTE plasmas)the following was proposed.We will develop two advanced models for improving atomic physics for the hydrodynamic simulations of laser plasmas. These will be delivered as ancillary Fortran components for hydrodynamic codes.:1)- For the Equation of State (EOS) in laser produced ICF plasmas, we envisage an average atom model embedded in a constant external potential (due to a neutralizing background of free electrons and ions) and contained in a ion sphere. The novelty is the treatment of quasi-free electrons (a.k.a shape resonances). These will ensure smooth variations of the free energy, allowing numerical differentiation to obtain entropy and other relevant quantities. In addition, the pressure can be obtained directly from the virial theorem if relativistic wavefunctions are used. An extension to non LTE (non Local Thermodynamical equilibrium) is also proposed.2)-A detailed level accounting (DLA) model for the opacity of simple to medium spectra. In contradistinction to statistical models that are widely in use, this detailed model will be correct for systems at low density and high temperature, as in the corona where high Z elements are used. In particular, it will be able to handle metastable levels that can modify noticeably the charge distribution.We will also design, manage the construction, and modification of a time resolved, and absolutely calibrated instruments for Laser Plasma Interaction studies.

New contract award from NRL’s Space Science Division
Artep has been awarded a new five-year contract to continue science and engineering support for NRL’s Space Science Division. This work currently supports a number of key satellite and rocket programs, that include Solar-B, SECCHI, SHIMMER and VAULT.
On going contract with NRL’s Plasma Physics Division
Artep is in the midst of a five-year contract supporting theoretical and laboratory experimental science being conducted by NRL’s Plasma Physics Division.Title: Analysis of the interaction of radiation with non-LTE plasmasThe Naval Research Laboratory Laser Plasma Branch successfully built in recent years a kilojoule-class KrF laser called the Nike Facility. An important purpose of Nike is to investigate various methods of controlling hydrodynamic instabilities in laser accelerated targets. One of the primary methods considered uses controlled amounts of high Z-generated radiation that preheats the ablator, thus modifying the density profile of the target while leaving the fuel on low isentrope. The interaction of intense laser light with a target is known to have several features that are essentially non-LTE, due to the existence of temperature and density gradients, and optically thin regions. To take into account non-LTE effects with the same accuracy as the Super-Transition-Array (STA) model does for LTE, the NRL Laser Plasma Branch implemented the approach of Busquet, showing generally satisfactory agreements when compared with benchmark computations.In support of the Nike target design effort Artep scientists are carrying out the following studies:Using STA to generate opacities for materials and mixtures specified by the target development team.Validating target design by comparing the measured emitted X-ray spectra from the target with theoretical predictions.Improving the Busquet algorithmInvestigating ways of representing the target radiation field in a collisional radiative model such as the SCROLL and FAST that could be interfaced in a satisfactory manner. (FAST is radiation hydrodynamic code that uses LTE atomic physics to calculate opacities of various materials and SCROLL is a super configuration collisional radiative model).
New contract award from NASA Goddard Space Flight Center
Artep has been awarded a new three-year contract with NASA to study the transition region explosive events and their relation to the solar magnetic field.Magnetic field restructuring by reconnection is pervasive in astrophysics and in particular in solar physics. Magnetic reconnection can potentially provide the energy to heat and accelerate the plasma in the solar atmosphere, but it has proved elusive to direct observations.Explosive events are thought to be an observable manifestation of small-scale reconnection in the transition region of the solar atmosphere. Using simultaneous data recorded bySUMER, MDI and EIT all instruments on the Solar and Heliospheric Observatory (SOHO) and from the Transition Region and Coronal Explorer (TRACE) Artep scientists are engaged in the following studies:Pinpoint the spatial relationship between the photospheric magnetic field structures and explosive events in the quiet Sun, active regions and coronal holes.Characterize the dynamic and energy budget of explosive events in relation to the magnetic field.Find signatures of magnetic reconnection in the solar corona.
