• 00:00 (UTC) Country France Type of Contract Temporary Job Status Full-time Hours Per Week 35 Offer Starting Date 1 Jan 2027 Is the job funded through the EU Research Framework Programme?

Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? No Offer Description The postdoctoral researcher will be responsible for conducting ultrafast pump-probe studies on solvated molecules in helium droplets. To achieve this, the candidate will utilize the laser experimental setup available at the ISMO laboratory. Femtosecond dynamics (ranging from tens to hundreds of femtoseconds) can be conducted at ISMO using the laser system developed by the DIRAM team. Additional studies may be carried out by relocating the

GOUTTELIUM

experiment to local laser facilities (such as ATTOLab). The candidate will also be responsible for preparing the relocation of the experiment to these sites. These experimental campaigns will enable the probing of molecular dynamics on timescales of a few femtoseconds, thus complementing the existing experimental capabilities at ISMO.

• Synchronization of TPX3CAM detection with high-repetition-rate lasers (1 kHz to 40 kHz)
• Managing the coincident detection of ions and electrons, which will be implemented by our team
• Characterization of pump and probe laser pulses
• Conducting pump-probe experiments using the

GOUTTELIUM

device and the laser system at ISMO or at host infrastructures ISMO is a leading laboratory in molecular physics and its applications, located at Université Paris-Saclay in Orsay (Essonne). ISMO operates at the intersection of multiple fields, including astrophysics, atmospheric chemistry, biology, and medicine. The DIRAM team specializes in the dynamics of all types of systems, particularly using a time-resolved approach, both experimentally and theoretically. The postdoctoral researcher will work in close collaboration with the

GOUTTELIUM

project leader. L'équipe DIRAM a une activité dédiée à la dynamique des systèmes de tout type, en particulier avec une approche résolue en temps, d'un point de vue expérimental ou théorique. Le/La post-doc travaillera en étroite collaboration avec le responsable du projet

GOUTTELIUM.
