Positron Systems is commercializing innovative technologies that provide new insights in the nondestructive inspection industry. The focus is on techniques that quantify changes in component material nanostructure induced by operational conditions and surface treatments. There are currently two technologies - Induced Positron Analysis (IPA) and Phase Contrast Analysis (PCA). Induced Positron Analysis (IPA) is currently being commercialized as a non-destructive technique to assess fatigue, creep, thermo-mechanical and embrittlement damage for example, in critical components made of metal and metal alloys, from initial manufacturing through onset of minute fracture. IPA technology, developed at the US Department of Energy's Idaho National Laboratory and licensed to Positron Systems, Inc., provides a new approach to assessing current damage and assists in predicting useful remaining life in many critical components based on the measurement of changes in the crystal lattice structure of the material. IPA quantifies damage in materials by inducing positrons into the material, which seek-out defects in the atomic lattice structure and react with their anti-matter (free electrons) differently than they would in 'as manufactured' material. This provides a measurable energy distribution response characteristic of changes in the lattice structure. Phase Contrast Analysis (PCA) is currently being commercialized as a non-destructive technique to assess many defects, in critical components made of any material from pure metal to advanced composite. PCA technology, developed in the medical industry by MXI Systems, Inc and licensed to Positron Systems, Inc. for the non destructive testing industry, provides a new approach to assessing current damage and assists in predicting useful remaining life in many critical components. PCA provides a monochromatic X-Ray image of material and can be tuned to 'read' any material. It's first objective is to assess the structural integrity of major assets, such as aircraft, without removing the skin.
