You will be part of a larger project developing the next generation in airport security. One of the steps is to identify explosives using their X-ray signature. Your work will be to examine the use of Molecular Dynamics (MD) as an augmentation to laboratory measurements with X-rays. The MD simulations will supplement a database of X-ray signatures of materials.
A consortium consisting of companies within design, technical science and behavioral science is together with the NEXMAP section of DTU Physics developing a new platform for the security check point in airports. Part of these will be advancing the scanning technology to allow complex electronics and liquids to remain in the luggage. To achieve this, the equipment needs to be much more accurate in the detection capability. The signatures from X-rays interacting with the luggage will be used for identification of illicit materials. MD simulations will allow us to calculate signatures of shock sensitive materials that are not safely handled in laboratories.
The project will consist of both MD simulation and prediction of the signature from the obtained results and validation of the model with data acquired in our new experimental facilities. The validation will be performed using nonhazardous substances with materials properties close to the restricted explosives. An introduction to the instrument(s) to enable experimental materials characterization will be included in the project.
