Additive Manufacturing

e. Additive Manufacturing Instruments (detectors and optics) for High Energy Physics experiments are often characterized by large areas or large volumes, need exquisite performance and need to be composed of materials that have to withstand harsh conditions, such as ultra-cold, high pressure or high radiation. Additive manufacturing technologies using Powder Bed Fusion, based on selected laser melting or electron beam melting, or Direct Energy Deposition manufacturing, based on laser or e-beam, using a powder or wire-fed process, and low-loss dielectrics (e.g., silicon, alumina, and ceramics) are of interest to address critical technical challenges in HEP. Areas of particular relevance are embedded cooling structures, low-mass support structures and micro-capillary arrays, support structures with high thermal conductance and low thermal contraction, and low-loss dielectric optics with built-in anti-reflection coatings for mm-wave transmission. Proposals that do not address a specific need of a specific HEP experiment will be considered non-responsive. Questions Contact: Helmut Marsiske, helmut.marsiske@science.doe.gov
