ATW 2016

Event Successful!


The ATW 2016 event has taken place and has been a great success. You find below the original final announcement with links to some papers provided by the lecturers to better prepare to the workshop, and a few selected presentations' slides.

Below a little video commemorative of the event.

Aerospace Thematic Workshops at Aussois - Final Announcement

Fundamentals of Collisions of Fast Particles with Surfaces

September 11-16 2016, CNRS Conference Centre Paul Langevin, Aussois, France

The 2016 AEROSPACE THEMATIC WORKSHOP on "Fundamentals of of Collisions of Fast Particles with Surfaces" will take place during the week of 11-16 September 2016 at the well known CNRS Conference Centre Paul Langevin, Aussois, at the heart of the beautiful French Alps. This is the very first conference of its kind, in a consecrated series dedicated to the fundamental issues of scientific disciplines relevant to aeronautics and space.

Previous editions of the workshops were dedicated to flow and combustion control by plasmas and held in Villa Monastero, Italy (2007), Les Houches (2009, 2011 & 2015) and Aussois (2013).



The workshop aims to survey the state of the art of our knowledge in the physics and chemistry of high-speed particle collisions (5000 -15000 m/s, several eV energy) with solid surfaces, namely:

  • surface accommodation and subsurface bond breaking and damage
  • chemical abstraction, oxidation, etc.
  • atom exchange reactions
  • emission of radiation, absorption of radiation from the hot boundary layer and the reaction products and subsequent photo-chemistry
  • reaction of the ablated elements with the boundary layer of the incoming fluid flow
  • ionization and plasma formation

All these mechanisms are present in several important applications and industrial domains:

  • Reentry heat shield design and manufacture
  • Energetic material explosive decomposition
  • Plasma Enhanced Chemical Vapour Deposition of semi conductors
  • Erosion of electrodes and insulators in plasma thrusters
  • Action of solar wind, Extreme Ultraviolet optics
  • Divertor interactions in fusion machines.

Besides, these issues are of fundamental scientific interest.

A fair level of understanding has been reached in these areas: refined quantum-mechanical approaches are used, sophisticated experimental methodologies have been developed and modelling has reached a high predictive level.

Yet it is felt that further progress may ensue from cross fertilisation between the communities concerned. It is the ambition of this workshop to gather their best leaders in order to discuss modelling of the physical-chemical phenomena, experimental diagnostic strategies, development of more resilient heat shields, better tailored explosives or flawless crystalline deposits. Some of these leaders from Europe, Russia and the USA have expressed their interest in the project and are expected to give very enlightening presentations.


All aspects of particle collisions with surfaces are to be covered, including applications, diagnostics and modelling. Young scientists and students are welcome. To stimulate presentation of novel ideas and open discussions, please note that there are no proceedings, that all participants are expected to attend the entire conference and are encouraged to submit posters. The format is very similar to that of Gordon Research conferences, thus allowing plenty of time for informal discussions and interaction between participants.

The conference is organized by:

Scientific Advisory Committee

The programme will feature twenty invited lectures. Presentations will address fundamental issues, experimental challenges, measurement methods and advanced numerical simulation.

Regular participants are encouraged to submit communications in poster format for review by the Committee.

To foster the exchange of novel ideas, there will be no papers nor proceedings.
