Radiation Resistant Stepper Motors

There is an unmet need for stepper motors that are radiation-resistant that perform critical functions and operations are an integral part of the beam line operations for the Facility for Rare Isotope Beams (FRIB) located at Michigan State University (MSU). There is currently no existing solution to this unmet need. Development of these stepper motors can enhance science and production of medical isotopes and enable increased beam power and total irradiation which is essential in the advancement of FRIB and many other high radiation facilities and reactors. To address this problem and opportunity we are/will be investigating, innovating, designing, developing, implementing and commercializing made-in-the-USA radiation-resistant stepper motor products that meet or exceed specifications/requirements, enable essential functions and operate in high radiation environments. Researched, developed and characterized and tested radiation resistant stepper motor designs and successful proof of feasibility for prototype radiation resistant stepper motor components. Performed pre- and post-irradiation experiments on the radiation resistant parts. Iterated as necessary to successfully achieve the Phase I objectives and goals for this project. Further research and development to enhance Phase I designs and then implement and test and characterize prototype radiation resistant motor products. Perform gamma and neutron irradiations on these motors. Iterate to achieve and commercialize a pre-production made-in-the USA product family of radiation-resistant stepper and servo motors. 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, these radiation resistant stepper motors 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 products 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.
