and devices for electronics, bioscience and engineering, and sensor systems. Neutral Buoyancy Research Facility The A. James Clark School of Engineering currently operates one of two neutral buoyancy tanks in the United States and is the only one in the world located on a college campus. The Neutral Buoyancy Research Facility was originally developed to support NASA studies of orbital operations, and Clark School students now use it for innovation and research. Radiation Facilities Includes a training nuclear reactor, a dry cell gamma vault irradiator, and a 10 MEV electron linear accelerator to support research and teaching. Robotics Realization Laboratory Space for students to design, build, and test robot designs. Facility provides robots for manufacturing and medical applications as well as for mechanical and electrical rapid prototyping. Tissue Engineering and Biomaterials Laboratory It is dedicated to developing biomaterials that improve the quality of life for ill or injured patients. It focuses on studying biomaterials for the delivery of therapeutics, scaffolds for orthopedic tissue engineering applications, and the interaction of biomaterials and tissues. Unmanned Aircraft System Test Site Research and operations facility to accelerate the safe and responsible application of unmanned aerial vehicles in private and public industry.
