Probing Saturns magnetosphere with auroral observations of Cassini and Hubble

The successful candidate will build and exploit a high level database of Cassini/UVIS auroral observations in the frame of the APIS service, and take advantage of multi-platform measurements to disentangle and characterize the different components of kronian aurorae (e.g. energy budget, dynamics from short-term scales to solar/seasonal variations) and constrain the underlying acceleration processes.

Project description:

The research project primarily aims at investigating the auroral processes and the dynamics at various timescales of Saturn’s magnetosphere, through the analysis of remote ultraviolet (UV) auroral observations recently acquired by the Cassini/UVIS spectro-imager and the Hubble Space Telescope (HST), complemented by in situ radio and plasma measurements of the Cassini spacecraft. The main objective of this project is to build and exploit a high level database of Cassini/UVIS auroral observations in the frame of the APIS service, and to take advantage of multi-platform measurements to disentangle and characterize the different components of kronian aurorae (e.g. energy budget, dynamics from short-term scales to solar/seasonal variations) and constrain the underlying acceleration processes. The Cassini ‘Grand Finale’, made of a series of high-inclination orbits, provided unprecedented vantage views on both the northern and southern UV aurorae together with unique in situ measurements along the auroral field lines. These observations were supported by coordinated HST instantaneous observations of the northern UV aurorae near solstice, precisely scheduled during the Cassini traversal of auroral field lines. Coincidentally, HST similarly observed the UV aurorae of other giant planets which offer an extended frame for comparative planetology.

Requirements for the candidate:
The applicant should master the basics of magnetospheric and auroral physics, have a documented past experience with space-based plasma observations and skills in massive data processing.

Location and starting date:
The project will ideally start in Sept. 2018 (or before) at LESIA-Observatoire de Paris, 5 place Jules Janssen, 92190 Meudon, France.

Salary: in the range 3000-3200€/month (gross), according to experience.

Duration: 18 months.

Apply: Application deadline is fixed on April 30th 2018. Applications with CV, copies of degree diplomas and grades, two reference letters, and copies of any previous research-related work statement of motivation.

The application should be sent preferably by e-mail to: laurent.lamy@obspm.fr

Controlled discharges for the miniaturization of plasma-catalytic reactors 

 

The goal of the  project is to use pulsed discharges generated close to a catalytic material in microchannels, as a way of improving the performance of micro-structured plasma-catalytic reactors for energy and environmental applications.

Project description:

In this project, we propose to use a specific type of pulsed discharge generated directly in the micro-channels of a catalytic reactor. The properties of this discharge in term of topology, control of the energy deposition rate make it a very promising candidate in order to:
-       Achieve a finer control of the plasma interaction with the catalytic bed and thus improve the experimental characterization of the processed involved.
-       Optimize the operation of these microstructured reactors for CO2 conversion or VOC abatement
The goal of the present project is therefore to use these discharges generated close to the catalytic material in the microchannels, as a way of improving the performance of micro-structured plasma-catalytic reactors for energy and environmental applications. The key objectives are:
•          Design a new catalytic reactor to apply repetitive pulsed discharge in micro-channels
•          Characterize the interaction of the repetitive pulsed surface discharge
•          Quantify the performance of this new catalytic plasma reactor for CO2 hydrogenation/VOC abatement.
To date none of the plasma-catalytic systems reported in the existing literature make use of the type of controlled discharge foreseen in this study.

The foreseen work program is:

WP1 (month 1 to 6) - Design and construction of a micro-structured reactor and the surface discharge system: The objective of WP1 is to build a catalytic plasma micro-reactor consisting of one or several channels where the surface discharge will be generated.

WP2 (month 7 to 12) - Characterization of the discharge and its interactions with the solid surface: The objective of WP2 is to characterize the discharge generated in and onto the channel(s) of the reactor built in WP1. At the end of WP2 an optimized reactor prototype will be available for its testing in the presence of a reactive gas atmosphere.

WP3 (month 13 to 18) - Plasma-catalytic experiments, characterization of performance and excited species in CO2 hydrogenation and VOC abatement.

 

 

Requirements for the candidate

We seek a candidate with a PhD. in physics, mechanical engineering or chemical engineering.
The successful applicant should be self-motivated, have the capability to work in autonomy as well as in in a highly collaborative manner. Good knowledge in both written and spoken English is required.
Skills:
-       Demonstrated experimental skills in either cold-plasma physics or plasma technologies for process intensification.
-       Ideally, knowledge in high-voltage system operation, pulsed power or in chemical reactors assisted by plasma.
-       Good academic writing skills.

 

Location and starting date

The project foreseen starting date is May-June 2018.
Over the 18 months of the project, the postdoctoral fellow will split his time between Onera’s premises (Palaiseau) and IJLRA’s premises (St Cyr l’Ecole), depending on the project requirements. In total, the fellow shall spend around 8-9 months at Onera and around 9-10 Months at IJLRA.

Apply

Applications with CV, copies of degree diplomas and grades, two reference letters, and copies of any previous research-related work statement of motivation.
Note : Onera enforces a restricted access policy. The final acceptance of the applicant requires the approval of the access request[1] by the administration.

The application should be sent preferably by e-mail to both:

P.-Q. Elias (ONERA) AND E. Galvez-Parruca (d'Alembert).
