Elmar Slikboer winner of the 2019 René Pellat Prize from SFP
We are pleased to congratulate Elmar Slikboer on being awarded the René Pellat 2019 prize by the French Physical Society. This prize is awarded once a year to a young researcher who has carried out exemplary work in plasma physics (hot, cold, natural) and is therefore awarded this year to a doctoral student co-supervised at the LPP.
- Elmar Slikboer et le jury de sa soutenance de thèse, le 26 novembre 2018
Elmar Slikboer carried out his thesis between three laboratories under the co-supervision of A. Sobota of the Eindhoven University of Technology (TU/e), E. Garcia Caurel of LPICM at the Ecole Polytechnique and O. Guaitella of LPP. In 2018, he obtained a double doctoral degree in TU/e with "cum Laudae" and in Ecole Polytechnique with the thesis prize of the Ecole Doctorale Ondes et Matières.
His subject was to develop a Mueller polarimetric imaging method to be able to characterize the interaction of plasma at atmospheric pressure with dielectric surfaces. From the analysis of the polarization changes of a light beam induced by a sample exposed to plasma, the birefringence, diattenuation and depolarization properties of the sample can be determined. Elmar Slikboer has successfully developed the instrument and algorithms necessary for data processing to apply these measurements to samples exposed to helium plasma jets in kHz regime. He was then able to obtain several striking results : the deconvolution of the axial and radial components of the electric field induced by the charges adsorbed on an electro-optical crystal could be measured, and for the first time quantitatively compared to the results of a fluid model developed by A. Bourdon and P. Viegas at LPP. In addition to the electric field components, Elmar showed that the birefringence signal also contained information on the temperature gradient induced in the target by the plasma. But all the power of this method appears in the electric field measurements made through biological tissues exposed to plasma jet. It was only through the separation of the depolarization signal that a sample as complex as onion cells could be analyzed to determine the plasma-induced electric field in this biological sample.
This work opens a new way for the study of plasma/surface interaction at high pressure, whether in catalysis, plasma medicine, or for polymer deposition for example. They have been the subject of 7 publications.
