Job openings

Aachen, Germany

The Nuclear Verification and Disarmament Group, sponsored by a FREIGEIST-Fellowship of the VolkswagenStiftung, is a junior research group that conducts research on verification approaches to make progress on nuclear disarmament. The research lies at the crossroads of experimental physics, computational nuclear engineering as well as the social sciences. It seeks to develop new “nuclear archaeology” tools to reconstruct how much weapons-usable materials have been produced in the past.

More information: https://www.aices.rwth-aachen.de/en/about-aices/about/institutes/nuclear-verification-disarmament

The group is part of the graduate school Aachen Institute for Advanced Study in Computational Engineering Science (AICES), which conducts interdisciplinary research at the interface between mathematics, computer science and engineering. The group also works together with the III. Institute of Physics B, which conducts research in the field of experimental particle and astroparticle physics.

Your responsibilities

Plutonium is produced in reactors and must be subsequently separated from the reactor fuel in reprocessing plants, producing radioactive waste. Highly enriched uranium is produced in enrichment plants, which also produces waste. Information on past production of weapons-usable fissile materials can be obtained today by analysing documentation of the past fuel cycle operations, and by analysing isotopic measurements of radioactive wastes of samples of structural materials from the fuel cycle plants.

In addition to developing techniques to gather relevant information from measured samples of wastes or from within facilities, inverse models must be developed that take into consideration all available information. They will be used to infer the most likely fuel cycle operation scenarios given the available data. This in turn will lead to fissile material production estimates. Uncertainties must be quantified. For this purpose, fuel cycle simulation codes will need to be advanced. Two key challenges will be that the documentation a state would provide to inspectors will likely not provide the full fuel cycle history in detail, and some parts may potentially be false. Therefore, measures to check the various sources of information for consistency and plausibility must be developed.

While the focus of the position is on research, you will to a limited extent be involved with teaching on topics related to your research, as well as with assisting in the supervision of students writing their theses.

What we offer

The successful applicant will be employed as a public servant. The salary corresponds to 100% of a EG 13 TV-L position.

This is a full-time position for two years. The possibility of an extension will depend on satisfactory performance and the availability of funding.

Saclay, France

The Laboratoire Leon Brillouin (LLB) is a French Research Infrastructure jointly supported by CEA and CNRS (http://www-llb.cea.fr). The LLB operates both as a large-scale facility and a research institute. Neutrons are an invaluable technique to study a large variety of issues, including, for biological ones, protein folding/unfolding. The structure and the dynamics of proteins can be elucidated by small-angle neutron scattering (SANS) and inelastic/quasi elastic neutron scattering (INS/QENS), due to the characteristics time and length scales probed by these techniques (from ns to few hundreds and from fraction up to several hundreds nm). So far, only few experiments have addressed the structure and dynamics of biological materials upon application of high pressure (HP).

The LLB has a long experience in the development of HP cells for SANS and INS/QENS. In particular, a HP device has recently been developed for SANS experiments up to 6 kbars and has been applied to study the role of ligands and hydrophobic cavities in the unfolding of myoglobin, a small globular protein. The project is to study the effect of pressure on the structure and dynamics of Cphycocyanin (CPC), a hexameric light-harvesting pigment-protein complex. CPC unfolding occurs through the dissociation of the hexamer into monomers until the complete unfolding of its subunits. Structural and dynamical changes may occur not only at “high” pressure (3-6 kbars), where proteins generally unfold completely, but also at “lower” pressure (1.5-2 kbars), where the input of water in the hydrophobic cavities of proteins may provide intermediate folding conformations so far undetected.

Starting date & Duration: As early as October 2018 ; 18 months

The successful candidate will be part of the “Soft Matter and Biophysics” scientific group. The position will allow the successful candidate to take advantage of the large in-house capabilities in biophysics research, neutron spectrometers, laboratory techniques, and access to the large scientific area around the “Plateau de Saclay”. Candidates are expected to have a PhD or similar in biophysics, biology, and/or biochemistry. Experimental experience in protein folding/unfolding would be highly appreciated. Experience with radiation techniques (X-ray or neutron scattering) would be advantageous.

Applications for this position should be sent by e-mail to sophie.combet@cea.fr and annie.brulet@cea.fr and include a C.V., the names of at least two references, and a cover letter summarizing current and future research initiatives.

Saclay, France

Recent years have seen a renewed interest for magnetoelectricity, as illustrated by the quickly increasing number of studies devoted to multiferroics materials. These fascinating materials present at least two ferroic orders, amongst the three widely known: ferroelasticity, ferroelectricity, and (anti)ferromagnetism. The coexistence of these two orders brings out multifunctionality, and new cross?coupling effects, that are particularly promising in areas such as data storage and spintronic : magnetoelectric coupling is indeed a key feature for potential applications, enabling the manipulation of magnetization with an electric field and vice versa.

The project steps outside the boundaries of the transition metal oxide compounds, mostly studied up to now, to investigate oxyborates with the ludwigite structure M3+(M2+)2O2BO3 (M is a transition element, divalent or trivalent). It associates mixed valence (di- and tri-valent ions) with a low dimensional network of transition metal atoms. The aim of the project is to characterize in details compounds belonging to this system, to identify new multiferroics/magnetoelectrics. Giant magnetoelectric effects have already been observed in Fe3BO5, but vast possibilities remain to induce such an effect by playing with substitution on the 2+ or 3+ sites of another transition element or a rareearth element, or by random site disorder by a non-magnetic element. On the technical side, the project will rely on the thorough characterizations of chosen oxyborate compositions, combining local and larger scale structural and physical characterization techniques (X-ray and neutron diffraction [LLB]), with physical properties measurements (transport, magnetization, dielectric constant, polarization, specific heat [CRISMAT]).

The candidate should hold a Ph.D. in solid-state chemistry or condensed matter physics, with a strong background in magnetism, and be capable of independent research as well as creativity. He/she should have a strong experience in neutron/X diffraction techniques, and powder diffraction data refinements. Experience with large scale facilities and magnetic structure determination would be appreciated. This research project requires a strong taste for experimental research and substantial autonomy. Good communication skills in oral and written English is essential.

Applications for this position should be sent by e-mail to gregory.chaboussant@cea.fr and include a C.V., the names of at least two references, and a cover letter summarizing current and future research initiatives.

Saclay/Paris/Grenoble, France

In the general framework of nanomagnetism, this research subject deals with fundamental properties of new magnetic materials (molecular magnetic clusters, magnetic nanoparticles) displaying functional properties associated to the control of magnetization at the molecular level or at the individual nanoparticle level. These “switchable” molecular solids are promising materials for high-density optical memory devices, especially since synthesis and deposition techniques now allow thin-film organisation and the size/shape control of magnetic particles. Molecular materials with so-called “spin transition” properties are capable to drastically change their magnetic state (from a non-magnetic state to a ferromagnetic or antiferromagnetic state) upon temperature variation or under light radiation. In some materials, diamagnetic ions are converted into paramagnetic pairs through light excitations. These states are generally “metastable” and can be reversed with temperature.

The tasks of the project are to study the structural and magnetic properties of coordination nanoparticles (CNPS’s) based on Prussian Blue analogues complexes, CsNiCr and CsCoFe, and core-shell type CNP’s. These novel systems open new possibilities for the design of molecule-based switchable objects where magnetism may be controlled or tuned by an external perturbation (light, temperature, field, etc.). The project aims at understanding the magnetic conformations of the nanoparticles and their eventual interactions. The methods of investigation will include small-angle scattering (SANS, SAXS), neutron diffraction, Inelastic Neutron Scattering (INS), and magnetometry (DC/AC) using SQUID and PPMS. Part of the work will also consists in developing new setups for in situ low-temperature photomagnetic studies under magnetic fields. Neutron experiments will be carried out at the LLB (CEA Saclay, south of Paris) and/or at the Institute Laue-Langevin (Grenoble).

The candidate should hold a Ph.D. in condensed matter physics or materials science, with a strong background in magnetism, and be capable of independent research as well as creativity. He/she should have experience in neutron/X scattering techniques (preferably SANS/SAXS) applied to condensed matter physics. This research project requires a strong taste for experimental physics (cryogenic work, superconducting coils, laser devices, sample preparation) and a substantial autonomy in both experimental and theoretical work. Strong communication skills in oral and written English is essential.

Applications for this position should be sent by e-mail to gregory.chaboussant@cea.fr, and include a C.V., the names of at least two references, and a cover letter summarizing current and future research initiatives.
