In the first year of the project, the MULTISCAN consortium focused on the design of the future system by sharing complementary partners expertise on the main technological bricks (laser, beam transport, conversion chamber, detector design, 3D reconstruction…). One part consisted of the clarification of use cases and requirements for such system with the collaboration of customs partners. In parallel a large simulation work was done on the study of the laser production and the 3D tomographic reconstruction. Different detector technologies were also studied and developed during this first phase of the project.
During the second year of the project, simulations were carried out to confirm the feasibility of X-ray production by the laser-plasma interaction and to optimize the geometrical configuration for the 3D image reconstruction. Regular working meetings were organized in person with the partners to progress on various aspects such as: the design of the conversion chamber, the beam transport, different kind of beam distribution systems were proposed and discussed. The optimization of the detectors technology and geometry have been finalized with the fabrication of a mock-up of detectors delivered and currently being tested at SMITHS facilities. Technical developments and validation of technological components also took place, including first measurement campaigns at XXL-CT which permit to obtain experimental data for 3D reconstructions modelling. Measurements will be done in the next weeks at LOA facilities with the conversion chamber to produce the first X-ray beams. Several detectors (such as beam monitoring, dosimetry), developed on the project will be tested during these X-ray production campaigns.
