Liste des stages M2 (en français)

ATTO - Attophysique

• Attosecond spectroscopy of molecules in gas and liquid phase
  Field: CHIMIE / Chimie-physique,    Laboratoire : LIDYL/ATTO
  Contact: MARROUX Hugo,
  
  

  Abstract: The student will use attosecond laser techniques to study ultrafast dynamics of molecules in liquid and gas phase. Inner level photoionization will be used to study in real time: diffusion/rearrangement/electron transfer dynamics, as well as solvation effects.

DICO - Dynamique et Interactions en phase COndensée

• In situ Evaluation of the efficiency of grafted nanoparticle under extreme electron dose rates
  Field: CHIMIE / Chimie-physique,    Laboratoire : LIDYL/DICO
  Contact: BALDACCHINO Gerard,
  
  

  Abstract: The objective of this training project is to probe the capability of NP-Pt tagged with RhB to enhance the effect of the beam coming from the laser-plasma driven electron accelerator, and to use this protocol to characterize and quantify their efficiency to improve radiation effects when submitted to extreme dose rate electron bunches such as FLASH. It includes measurements and in-depth analysis of the of NP-PtRhB fluorescence intensity to probe in real time the fast chemical changes in cells and determine the local dose deliver. We plan to measure the fluorescence yields in different cell lines (HeLa, PC3, U87 glioblastoma, BxPC3 pancreas, fibroblast) cultivated in classical monolayer culture mode (2D).

• Ptychographic lensless imaging on a short wavelength laser
  Field: OPTIQUE / Optique,    Laboratoire : LIDYL/DICO
  Contact: BOUTU Willem,
  
  

  Abstract: Coherent diffractive imaging is a lensless imaging technique that makes use of spatial coherence and Fourier optics to reach spatial resolutions of the order of 10s to few nanometers. The aim of this internship will be to implement ptychography, a scanning coherent diffractive imaging technique, on a new laser high harmonic source working at 20 nm.

• Spectral phase measurement of laser high order harmonic emission from crystals
  Field: OPTIQUE / Interaction laser-matière,    Laboratoire : LIDYL/DICO
  Contact: BOUTU Willem,
  
  

  Abstract: The aim of this internship is to install and test a new experimental setup to measure the spectral phase of the laser high order harmonic generation radiation resulting from the interaction between femtosecond laser pulses and semiconducting crystals, in the deep ultraviolet spectral range, inaccessible to standard detectors.
