Anna Grassi started her PhD in 2014.
She works on Relativistic shocks in magnetized plasmas in the context of laboratory astrophysics at LULI with C. Riconda, LULI and A. Macchi, UNIPI.
In this video, Anna explains the originality of her project, her results and her vision of PLAS@PAR!
"It was interesting to do my My PhD studies with PLAS@PAR, because PLAS@PAR was able to create a very rich environment in which students, researchers from many different fields of plasma physics and even private companies can find a place to collaborate, exchange ideas and discuss. This was very helpful and creates very productive and creative context for a PhD."

Bruno Honnorat started his PhD in 2014.
He works on non thermal plasmas for biomedical applications at LPP with A. Rousseau.
In this video, Bruno explains his research objectives, his collaborations and his results!
"I study the biomedical applications of plasmas, it means that I am studying the biological effect of cold plasmas on living organisms (...). We are particularly studying the neck and throat cancers. (...) The objective is to improve the quality of life of patients, with a regression of the tumor size, for example, to render tumors operable or to remove totally the cancer through Plasma treatment."

PLAS@PAR is pleased to announce the thesis defense of Raj Laxmi Singh (LPP/Lerma) on March 2, 2017 at UPMC (24-34 - 5th floor, room 509) at 10am.
Raj started her PhD in November 2013 with Jean Larour (LPP) and Chantal Stehlé (LERMA).
Title: Strong radiative shocks relevant for stellar environments: experimental study and numerical approach
Strong shocks are present in various astrophysical phenomena. Such shocks are strongly influenced by the radiation through its coupling with hydrodynamics. Thus their topology and dynamics are quite complex. Generating such hypersonic shocks in the laboratory, with controlled conditions, is thus an adequate tool to study the influence of radiation and to compare them with numerical simulations. Such shocks can be generated by intense lasers and electromagnetic devices. The first part of this dissertation concerns the numerical and experimental study of the interaction of two counter propagating laser-driven shocks. The experiments, performed at the kJ PALS laser facility allowed to generate shocks with different speeds (~ 30-55 km/s and 10-25 km/s), in noble gases and low pressure (less than 1 bar). Several diagnostics were implemented: visible interferometry, time- and space-resolved visible spectroscopy, and time integrated XUV spectroscopy. Our experiment shows a strong interaction of one radiative precursor onto the second one. The physical parameters of the plasma were deduced from the diagnostics and compared with 1-D simulation results. The second part is devoted to the design of an experiment where the shock is generated electromagnetically. The optimization of this generator is presented and also the full experimental set up which allows studying shock ~ 30 km/s in noble gas at ~ 1 mbar.

Education in one of the pillars of PLAS@PAR

Every year, the Labex organizes multiple actions to promote plasma physics in education, at the Bachelor, Master and Doctoral levels (hands-on activities, teaching programs, summer school, scolarships for French and International students…). PLAS@PAR also encourages and support new initiatives (for instance, the new hands-on experiment in Jussieu).
This academic year, PLAS@PAR is going further and reaching a broader audience!
Plasmas represent 90% of the known matter, plasmas are everywhere from the sun to the stars, in lightnings, fire and even in neon lights: Plasma physics can be easily taught to school audiences. To reach this goal PLAS@PAR offered a 2-day training in December 2016 at UPMC to future professors from the "Master des Métiers de l'Enseignement, de l'Education et de la Formation (MEEF), parcours physique-chimie".
This training (in French) entitled « Les plasmas dans tous les leurs états ! » was accessible with a basic knowledge of physics and was a great occasion to give some simple key information and tips to allow teachers to talk about the 4th state of matter to their future students. 5 researchers collaborated to create this training and 9 future professors were participating.
The training was focused on 3 main activities:
- Discussion & presentations about all types of plasmas
- Hands-on experiments
- Visits of facilities and experiments (in particular the SIMPA ion source from INSP, Institut des NanoSciences de Paris)
The full program is available here.
The initiative was a true success: trainees are now able to teach some key notions to hundreds of future school students.
The training will be renewed next year!

This year @UPMC, students in Physics (Third year of Bachelor’s degree – L3 & First year of Master’s degree « Physics & Applications » - M1) apprehend fundamental concepts of Plasma physics thanks to a new hands-on experiment called « Plasma discharges – Langmuir probe ».
This Teaching Unit allows students to become familiar with fundamental processes in plasma physics.

Learn more about this new hands-on experiment
A glow discharge is a plasma (ie. a gaz containing ions and free electrons thanks to an electric current). We focus here on discharge tubes commonly (and inacurrately) called "neon". These glass tubes are subjected to a very low air pressure. By pluging a high-voltage supply to the metal electrodes of the tube, we create a very high electrical potential (around a few hundred volts DC). From a « disruptive » value, a breakdown can be observed: the gas becomes conductive and releases a large number of electrons. Then, a plasma appears between the electrodes. Student objectives:
- Students have to quantitatively measure the breakdown voltage of a tube under a given residual gas pressure; Then, students are able to verify the Paschen law.
- Students qualitatively study the light emitted by the plasma’s glow discharge (by image analysis) and highlight that inelastic electron/ion collisions are the source of this light emission.
- Students measure the floating electrostatic potential within the plasma and highlight the inhomogeneity of the electric field inside discharge (screening effects).
- The Langmuir probe allow them to measure the temperature of electrons in the plasma.
- A spectroscopic study help identify more precisely the ions and their excited states formed in the glow discharge.
This hands-on experiment was created in collaboration with INSP (Institut des NanoSciences de Paris) the experimental platform of the Physics Faculty @UPMC and the Cluster of Excellence PLAS@PAR.More information about plasma physics education (summer school, grants for international internships, scolarships, etc) here.

Le numéro 10 du journal Aerospace Lab est consacré aux plasmas appliqués à l’aéronautique. L’utilisation des plasmas pour l’aérodynamique et la combustion a attiré un intérêt grandissant ces vingt dernières années, et toute une communauté scientifique se consacre désormais à ce domaine de recherche. Le contenu de cette édition spéciale reflète la diversité des applications et des conditions physiques dans lesquelles les plasmas sont étudiés : des écoulements subsoniques aux écoulements supersoniques, des chambres de combustion aux écoulements externes, et des plasmas thermiques aux plasmas froids. Sont couverts à la fois les travaux expérimentaux et les efforts de modélisation, car la double approche est nécessaire pour faire face à la complexité de la physique en jeux dans les plasmas. Au final, le but de cette édition spéciale est de montrer au lecteur l’étendue de l’activité actuelle dans ce nouveau domaine de recherche, et de donner un aperçu des nombreuses études et applications des plasmas qui sont à venir dans le domaine de l’aéronautique.
