A composite is a combination of two or more materials that yield a new material with desired properties (i.e., non-magnetic/magnetic or non-conductive/conductive).  Our specialization is in design and fabrication of high performance Carbon Fiber structures and precision bonded assemblies (incorporating both metallic and composite components) for Silicon Tracking Detectors. Using carbon fiber composites, we design very low mass, ultra-stable support structures for Silicon Tracking Detectors used in High Energy and Nuclear physics experiments. Our designs often integrate cooling, data, and power into the support modules. In addition to Silicon Tracking Detector Structures, we use carbon or other fiber composites to develop supports for other structures, including apparatuses at the Advanced Light Source (ALS). The Berkeley Lab Engineering has developed techniques and tooling to design and fabricate these structures with precision.
