The 5th International LII Workshop provides a forum for open high-level discussion on the understanding of LII diagnostics and to foster relationships in joint research. Leading researchers, engineers, officials, students and others are invited to attend and participate for a successful outcome of the workshop.
Laser-induced incandescence (LII) has proven to be a powerful tool for particle concentration and particle size measurements in combustion, particle synthesis, as well as in environmental applications. However, different experimental approaches and data evaluation techniques exist which, while demonstrating the complexity of the physical processes involved in LII and the need for further research, has also somewhat hampered the acceptance by industry of LII as a measurement standard. In order to strengthen the community and to explore the development of a series of best practices for LII modeling, experiments, and data interpretation, a series of workshops was initiated in Duisburg, Germany (2005), followed by workshops in Bad Herrenalb, Germany (2006), Ottawa, Canada (2008) and Varenna, Italy (2010). These meeting were highly successful with differences in models reduced and some best practices in experimental methods demonstrated.

The 5th International workshop on Laser-induced Incandescence will be held at Le Touquet, a nice commune located in the North Pas-de-Calais region, on The Channel (La Manche in French), from 9 to 11 may 2012.



The Fifth International LII Workshop will combine contributed technical presentations, related to the scientific development of Laser-Induced Incandescence modeling, experiments, data interpretation, and coupling with other techniques, with organized discussions on the current best practices and challenges facing LII as a measurement standard for particulate aerosols.

Technical presentations

The conference is open to submissions on emerging issues related to LII and its establishment as a measurement standard. The submissions should not cover applications of standard LII but focus on aspects related to the measurement technique. Potential topics are:

  • Combinative measurements of LII, Light Scattering, luminescence, Laser Induced Breakdown Spectroscopy, diagnostics related to nanoparticles and soot precursors and more
  • Measurements in extreme situations, such as ultra high sensitivity, large-scale fires, remote sensing, near-wall measurements
  • Measurements in turbulent flames
  • Determination of materials constants
  • LII for non-carbonaceous materials
  • Other novel developments related to LII, new application fields (plasma…)
  • Industrial applications
  • Approaches to improve understanding the LII process

For this fifth “anniversary” workshop we also want to review the assessment of the status quo and the open questions discussed in the previous workshops. Attendees of the workshop are encouraged to provide their input to the development they have observed (and they have contributed to). The results are to be compared and discussed during the workshop and future research directions and scientific challenges will be discussed on this basis.

Organized discussion

The workshop will feature organized discussions related to the key areas of experimental techniques, modeling approaches, materials properties and model assumptions. In each of these areas, based on the community’s input, an assessment will be made of the state of the art, of the progress since the first LII workshop, and of the future research priorities. All potential participants are invited to submit input ahead of time. The input received will be assigned to leaders for each of the key topic areas. A new objective for this workshop is to identify and address hurdles faced in having LII accepted as an industry standard for particulate measurement. The unique capabilities of LII over other diagnostics will be identified and strategies developed to overcome inertia from industry in adopting LII.
Further information on the organized discussions will be announced by the topic leaders and be provided in the final program. Workshop attendees will be encouraged by the topic leaders to send material related to discussion topics.
If possible, agreement on standard models and standard material properties should be sought. The results will be made available after the conference on the internet (www.liiscience.org). Based on the remaining open questions topics for joint research activities will be discussed and fixed which will form the basis for preparation (through experiments and dedicated theoretical work) for the subsequent workshop.

Abstract submission

1-Page abstracts for contributed presentations should be submitted by March, 20th, 2012.
Abstracts must be sent to Diese E-Mail-Adresse ist vor Spambots geschützt! Zur Anzeige muss JavaScript eingeschaltet sein!.

Depending on the number of submissions, authors will be offered an opportunity to present their results either as oral presentation or poster. Poster sessions will form an integral and important part of the program.

General information and accomodation 

The work sessions will be held at “Le Palais des Congrès” located in the center of Le Touquet. http://www.letouquet.com/accueil/tourismedaffaire/nosespaces.aspx.
