INSP is a fundamental research laboratory that has been created in 2005 by gathering laboratories of very different cultures, and which focuses on confinement effects and related novel phenomena. It combines broad skills and knowledge in device manufacturing techniques, (such as growth of clusters, self-organized materials, molecular beam epitaxy, laser ablation, lithography), in characterization techniques (such as high-resolution spectroscopy and microscopy, local-probes, fast ion analysis system and slow multi-charged ion source) and numerical simulations. The INSP provides a very fruitful and stimulating environment grouping together scientists from different fields including atomic and molecular physics, materials science, optics, acoustics and chemistry and joined expertise on both theory and experiment. Research activities by the team involved in Plas@Par: Agrégats et SURfaces sous excitations intenses (ASUR).

ASUR’s scientific program is focused on the interaction dynamics of multicharged ions or intense laser pulses with complex media such as solids, surfaces and clusters. These two types of interaction lead to an excitation of matter under rather extreme conditions (production of highly excited states in intense electric field – higher than 109V/cm), to secondary sources of particles (electrons, ions and atoms) and x-ray photons and, finally, to modifications of material properties.ers/solids in intense fields; heavy ion beams; X-ray and particle spectroscopy.
The group research activity is dedicated to different interconnected topics including:
  • The interaction dynamic of clusters submitted to intense excitation sources on a sub-picosecond timescale;
  • The energy deposition by ionic species in irradiated material through the investigation of ion-ion collisions (the project FISIC @ SPIRAL2 leading to a broad program on atomic physics of Fast Ion – Slow Ion Collisions);
  • The structural and magnetic properties modification of surfaces submitted to bombardment of slow highly charged ions;
  • The development of theoretical models describing the collective or individual response of matter under extreme fields on an atomic scale.
The researchers are users of various national and international large scale facilities (mainly at GANIL (Caen) and GSI (Darmstadt, Germany) for the heavy ion part and at the LUCA (Saclay) for the intense laser source) and operates the SIMPA ion source (Source d’Ions Multichargés de Paris), a platform of the UPMC.
