New position of Iyas Ismail: a nice story within PLAS@PAR

Hello Iyas! Congratulation for this new position at CNRS, what a great achievement! We think that your story could interest many people, especially students regarding their professional career. Could you enlighten us about your background?

MY BACKGROUNG

After graduating in physical engineering from the Higher Institute of Applied Sciences and Technology (HIAST), Damascus Syria, I came to France to prepare the DEA (Master 2) “Rayonnement et Plasmas” at the Université́ de Provence (Marseille). Then I moved to the Université́ de Paris-Sud, Laboratoire des Collisions Atomiques et Moléculaires (LCAM), where I obtained a PhD degree in Physics (2005). After that, I came back to Syria, where I was nominated in 2006 as permanent researcher at the Atomic Energy Commission of Syria to work at the Ion Beam Accelerator Laboratory. In 2014, I was promoted to senior researcher at the same laboratory.

In 2015, PLAS@PAR offered you the opportunity to work on MOSARIX, an important and exciting project fully founded by the Labex. May you explain the project and your results?

MY WORK AT PLAS@PAR

Credit: Iyas Ismail, LCPMR

In 2015, I have been recruited by PLAS@PAR for a 3-years contract at LCPMR (Sorbonne Université). I was in charge of the development of a new X-ray spectrometer (MOSARIX) with high resolution and high efficiency allowing for the first time to measure the photons X (1.8 to 5 keV) in coincidence with ions or electrons.

As part of this project, I developed a new detector of photons based on microchannel plates (MCPs). This detector was a subject of a patent application (January 12, 2018)! The fast response of this detector allows coincidence measurements of photons with good time and spatial resolution. This makes possible to reach a spectral resolution <1eV over the entire energy range. I recently designed, built and successfully tested, at GALAXIES beamline of the SOLEIL synchrotron, a first version of this spectrometer. This allowed to test our simulations, validate the design and to move toward the construction of the final multi-crystals version of the spectrometer!

This project looks like a success story! It should be a plus for the permanent position you were looking for at CNRS. Can you explain us if there is a direct link between your work on MOSARIX and your new missions?

MY NEW MISSIONS AS A PERMANENT MEMBER OF THE LCPMR

Credit: LCPMR, https://lcpmr.cnrs.fr/

Yes, I will continue working on MOSARIX besides other new projects as well. Currently, I started working with two groups of the LCPMR using different heavy experimental setups: X-XUV spectrometers and electron spectrometer (magnetic bottle). These equipments can be used both at the laboratory and large-scale facilities (SOLEIL synchrotron and Free Electron Laser XFEL). I am interested in the development of these techniques besides the different scientific projects involved with. In addition, I have a project to combine MOSARIX with some of these spectrometers to make unique measurements of photons with high resolution and/or in coincidence with ions or electrons.

Can you precise your scientific goals?

My scientific objective is to study the processes occurring after excitation in inner shell of molecules using intense photon beams issued from third generation synchrotron or XFEL sources. Later on, it might be interesting to go toward to study larger molecules of biological interest owing to the unprecedented measurements of photons in coincidences with ions and electrons that can be performed with MOSARIX spectrometer and the different instruments of the LCPMR.

Thanks Iyas and good luck!

Happy new year 2019!

All the PLAS@PAR direction team wishes you a happy new year 2019, rich in scientific and personal success!

2019 will start with our annual Scientific day on February 14! This event will celebrate recent scientific achievements in our project thanks to the commitment of our community since 2012!

It will be followed by the launch of the European PIONEER project, a call for small innovative projects, thematic days, workshops and summer schools.

We are looking forward to see you all!

New publication: Plasma Atomic Physics

Plasma Atomic Physics presents the essential concepts and detailed information required for a better understanding of plasma physics

All authors are established experts on, and dedicated teachers of, atomic physics

The only modern book to treat this topic in depth

Addresses students, postgraduates, teachers and researchers

Combines elements of textbook and monograph style

Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers’ interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the “Plasma Atom”,where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density. Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models.

Imminent launch of the BepiColombo mission!

On July 6th, the European Space Agency (ESA) and JAXA (Japan Aerospace Exploration Agency) officially presented their first mission towards Mercury: BepiColombo, with two probes called Mercury Planetary Orbiter (MPO) and Mercury Magnetospheric Orbiter (MMO). The mission will be launched on October 19, 2018 at the Guyana Space Center, Kourou (October 20 European time). The probes will arrive at Mercury in December 2025.

3 plasma physics labs from the Paris region – LESIA, LPP & LATMOS – were highly involved in preparing this mission, especially in the instrumental part!

BepiColombo’s main goals

Mercury still has a lot of secrets for scientists. Previous missions such as Messenger and Mariner 10 discovered some important phenomena on Mercury such as polar ice, surprising blue hollows, volcanic mechanism… BepiColombo is going further thanks to 2 probes which will provide more accurate information: MMO will study the magnetosphere and its interaction with the Solar Wind and MPO will study the magnetosphere close to Mercury, the surface, the atmosphere and the interior of Mercury!

Contribution of LPP – Laboratoire de Physique des Plasmas (UMR 7648 Sorbonne Université, CNRS, École Polytechnique, Université Paris-Sud, Observatoire de Paris)

The LPP (Laboratoire de Physique des Plasmas) is contributing to 2 experiments onboard the MMO probe and that are parts of two consortia: Plasma Wave Instrument (PWI) and Mercury Plasma Particle Experiment (MPPE).

     - The MSA (Mass Spectrum Analyzer) is an instrument dedicated to measurements of the plasma composition. Its main goals are : the study of the solar wind and of the material ejected from Mercury’s surface, the study of ion transport and acceleration in the magnetosphere, and the study of the interaction of the magnetospheric plasma with the planet surface and exosphere.

     - The dual-band search coil magnetometer - DB-SC (Double Band - Search Coil)  will measure high frequency fluctuations (waves) of the magnetic field. It will perform measurements of the B vector of electromagnetic waves in the low frequency band as well as measurements of an electromagnetic wave component in the high frequency band.

Contribution of LESIA – Laboratoire d’Études Spatiales et d’Instrumentation en Astrophysique (UMR 8109 Sorbonne Université, CNRS, Observatoire de Paris)

The LESIA (Laboratoire d’Études Spatiales et d’Instrumentation en Astrophysique) developed 2 instruments: the first one for the SIMBIO-SYS instrument onboard the MPO probe and the other one for the Plasma Wave Instrument (PWI) onboard the MMO probe.

     - VIHI (Visual and Infrared Hyper-spectral Imager) is an imaging spectrometer which will allow to achieve a complete and unique mapping of surface minerals thanks to an unprecedented spatial and spectral resolution. This information will help understanding the processes of differentiation and heating that contributed to the formation of Mercury.

     - SORBET (Spectroscopie des Ondes Radio et du Bruit Electrostatique Thermique) is a high-frequency radio wave receiver that will measure for the first time the density and temperature of the plasma in the Mercury environment (solar wind, magnetosphere and exosphere). SORBET will also be able to detect and study radio emissions from Mercury and to monitor solar radio emissions up to 10 MHz.

Contribution of LATMOS - Laboratoire Atmosphères, Milieux, Observations Spatiales (UMR 8190 Sorbonne Université, CNRS, Université Versailles Saint-Quentin)

The LATMOS (Laboratoire Atmosphères, Milieux, Observations Spatiales) also contributed to this mission with the spectrometer PHEBUS and a neutral and ion spectrometer PICAM that is part of the Search for Exospheric Refilling and Emitted Natural Abundances (SERENA) consortium. Both instruments are accommodated on the MPO probe.

     - PHEBUS (Probing of Hermean Exosphere By Ultraviolet Spectroscopy) is a dual optical spectrometer covering spectral ranges from extreme ultraviolet (EUV: 55-155 nm) to far ultraviolet (FUV: 145-315 nm). PHEBUS aims at characterizing the Mercury exosphere in terms of composition and dynamics, and the relationships between the surface and the exosphere.

     - PICAM (Planetary Ion CAMera) is an ion mass spectrometer operating as an all-sky camera for charged particles to study the chain of processes by which neutrals are ejected from the regolith, eventually ionized and transported through the environment of Mercury. PICAM’s detector and optics has been jointly developed by LATMOS and LPP.

Meet with Florian Condamine, PLAS@PAR young researcher - LULI - PhD student

Florian Condamine started his PhD in 2015.

He works on X-ray spectroscopy on dense plasmas produced by 4th generation Light Sources at LULI  with F. Rosmej.

“PIONEER” a brand new Marie Skłodowska-Curie Action on CO2 recycling granted by H2020 in 2018 on plasma-catalysis interaction!

The Innovative Training Networks 2018 (ITN) awarded PIONEER, a project submitted by O. Guaitella (LPP, École Polytechnique), M. E. Galvez (IJLRA, Sorbonne Université) and P. Da Costa (IJLRA, Sorbonne Université), all members of the Labex PLAS@PAR. The project will be managed by Sorbonne University in close collaboration with the École Polytechnique and the CNRS, supported by a wide consortium of partners (public and private)* in order to create a European Joint Doctorates program (EJD).

Recycling waste CO₂ is one of the biggest challenges of our time and of future generations. The use of plasma-catalysis to achieve efficient CO₂ conversion is an innovative and ambitious approach, requiring multidisciplinary expertises.

How to obtain this synergy? By training a new generation of research leaders able to address all the fundamental aspects leading to a successful implementation of plasma-catalytic CO₂ valorization technologies in Europe.

Indeed, the use of plasma-catalysis can potentially apply to any CO₂ conversion process, from its hydrogenation, including methanation, to its use in dry, autothermal or bi-, tri-reforming of methane containing gases, with their own specificities, leading to a coupled excitation of the gas mixture. The research and technological goals of PIONEER are therefore to forge “out of the box” catalytic materials capable of taking advantage of reactive species from the plasma as well as designing the most appropriate plasma sources suitable for each CO₂ recycling process.

This motivates the 3 research work packages within PIONEER:

- To gain deeper knowledge on the fundamentals and mechanisms of CO₂ plasmas interacting with surfaces and the physicochemical phenomena involved, including CO₂ dissociation, to model these phenomena and to be able to predict the behavior and consequences of different CO₂ plasmas.
- To invent advanced, active, selective and robust catalytic systems specially formulated for plasma-catalytic coupling to optimize CO₂ valorization, and study the interaction between the excited species present in CO₂ plasmas and solid catalytic surface.
- To explore innovative routes for plasma-catalyst interaction, study novel reactor designs involving various types of exposure of the catalytic materials to different kinds of plasmas of diverse energy density, to evaluate the influence of these parameters in reaction mechanisms, kinetics and product yield.”

PIONEER is scheduled to start on January 1st 2019.

Arts and Plasma sciences: an article in The Conversation

We invite you to read the article published in The Conversation on June 29, 2018 (in French): When arts and sciences of plasmas meet at the museum: issues of a crossed mediation.

A reflection on scientific and artistic mediation concepts around 3 notions: light, color and matter.

Plasma Reflection, Danny Rose

PLASMA REFLECTION : a workshop presented at Centre Pompidou in April 2018

"A generative and interactive artwork that makes it possible for visitors to see their own reflection in the fourth state of matter: Plasma.
Plasma Reflection is designed like a distorting mirror which would turn the matter of those who are facing it.
On the other side of the mirror, matter is ionized. It is Plasma. The silhouettes of those who stand or move in front of Plasma Reflection are diffused in space and are subject to the turbulence generated by the magnetic field. The installation lives with people who interact with it."

Inside Plasma, Danny Rose

INSIDE PLASMA : an immersive installation at the heart of the matter, presented at Centre Pompidou in April 2018

"An immersive artwork in which art meets science to create a synaesthetic experience of the fourth state of matter: Plasma.
From the infinitely large to the infinitely small, Plasma is the focus of a poetic approach-close to a dream.
The luminous sculptures that the plasma produces move and materialise in space, creating an illusion of volume that constantly alters perception.
The relationship of the work to the space and the spectator are the core of the scheme that takes shape Inside Plasma.
A continuous conversation of light, sound and the perception of space, this is a work made to be lived, felt and experienced."

New publication: Compressible Magnetohydrodynamic Turbulence in the Earth’s Magnetosheath: Estimation of the Energy Cascade Rate Using in situ Spacecraft Data

ABSTRACT

The first estimation of the energy cascade rate $\left|{\epsilon }_C\right|$ of magnetosheath turbulence is obtained using the Cluster and THEMIS spacecraft data and an exact law of compressible isothermal magnetohydrodynamics turbulence. The mean value of $\left|{\epsilon }_C\right|$ is found to be close to ${10}^{-13}J{m}^{-3}{s}^{-1}$, at least 2 orders of magnitude larger than its value in the solar wind ($\sim {10}^{-16}J{m}^{-3}{s}^{-1}$ in the fast wind). Two types of turbulence are evidenced and shown to be dominated either by incompressible Alfvénic or compressible magnetosoniclike fluctuations. Density fluctuations are shown to amplify the cascade rate and its spatial anisotropy in comparison with incompressible Alfvénic turbulence. Furthermore, for compressible magnetosonic fluctuations, large cascade rates are found to lie mostly near the linear kinetic instability of the mirror mode. New empirical power-laws relating $\left|{\epsilon }_C\right|$ to the turbulent Mach number and to the internal energy are evidenced. These new findings have potential applications in distant astrophysical plasmas that are not accessible to in situ measurements.
