Radiation-Resistant Stepper Motor

There is an unmet need for stepper motors that are radiation resistant that perform critical functions and are an integral part of the beam line operations for the Facility for Rare Isotope Beams (FRIB) located at Michigan State University (MSU). Development of these stepper motors can enhance science and production of medical isotopes by prolonging duty cycles of the motors and potentially increasing total irradiation time on a yearly basis and also employed at many other high radiation facilities and reactors. To address this problem and opportunity we propose to investigate, innovate, design, develop, implement and commercialize made-in-the-USA radiation resistant stepper motor products that meet or exceed all specifications/requirements, enable essential functions and operate in high radiation environments. Design, research, develop, implement, characterize and test radiation resistant stepper motor designs and implementations of proof of feasibility prototype stepper motor components. Perform pre and post irradiation experiments on the stepper motor components. Iterate as necessary to achieve the Phase I objectives for this SBIR-STTR. Public benefits include advancing equipment for accelerator applications, reducing equipment failures due to stepper motor issues. This allows for longer irradiation duty-cycles during a year and more capacity for scientific experimentation and medical isotope production at accelerator facilities. In addition, the radiation resistant stepper motors we aim to develop can be utilized in other areas, such as in reactors or enduring space radiation. The public further benefits from enhanced capabilities in radiation environments including those related to fission and fusion. Fusion reactors could be a powerful means of generating clean electricity which is of immense value to the public. This enables and supports advancements and enhancements for fusion systems and applications due to better, improved radiation-related insulation materials that can also be applied to other applications. The public will also greatly benefit from products that continue to drive cost down including for fusion energy while increasing USA manufacturing and creating USA jobs in fusion applications and clean, plentiful fusion-based energy generation.
