Posithôt's industrial NDT solution leverages a non-radioactive positron source to measure the density of defects ranging in size from nanometer to micrometer. It is intended for use on critical or very-high-added-value parts during design, manufacturing, operation, and maintenance. Posithôt's non-destructive testing (NDT) solution can measure the density of atomic-scale defects and predict, very early on, how they will evolve over time. The ability to effectively predict the appearance of microcracks, for example, can help parts manufacturers and users optimize designs, improve manufacturing processes, and adapt maintenance strategies, extending service life with a high degree of confidence. Industries that manufacture and use critical parts (space and defense) or that deal with high volumes (semiconductors) will benefit from the startup's solution. Its business model is based on defect density measurement services and the sale of equipment (the positron source) to end-users. Key figure: 1 Nanometer — Posithôt can measure defect densities at the nanometric scale—far more sensitive than the 0.3-millimeter capabilities of conventional NDT methods. KEY Markets: Aerospace, Defense, Semiconductors, Hydrogen industry. Technologies used: Non-radioactive positron source; Defect density measurement by positron annihilation spectroscopy.
