Kansas State University engineers have developed a lithium-based neutron detector that is being recognized as one of the year's Top 100 newly developed technologies.
R&D Magazine is recognizing Douglas McGregor, professor of mechanical and nuclear engineering, and his research team with a 2014 R&D 100 Award. The award recognizes the year's 100 most significant high-technology new products.
The university-developed lithium-based neutron detector, called the Li-Foil Neutron Detector, can be used for medical imaging, national security, scientific research, oil well logging and the automotive industry.
"We are honored to receive this international recognition for the collaborative efforts of students, faculty and researchers on our team," McGregor said. "All of the members of our team have worked very hard to advance this technology and take it to a whole new level. We continue to improve it and develop newer models."
An R&D 100 Award signifies that a product has merit as one of the most innovative new ideas of the year, nationally and internationally, and is recognized as a mark of excellence by national laboratories, universities, industrial companies and government agencies. The award honors technology developments that are designed to meet current or future societal, scientific or business challenges.
Researchers in McGregor's Semiconductor Materials and Radiological Technologies Laboratory, or SMART Laboratory, created the Li-Foil neutron detector. Other researchers involved include Kyle Nelson, research associate in mechanical and nuclear engineering; Steven Bellinger, research associate in mechanical and nuclear engineering; Niklas Hinson, recent bachelor's graduate in mechanical engineering, Goddard; and Benjamin Montag, doctoral student in nuclear engineering, Manhattan.
Nelson, who worked on the research for his doctoral project, created the neutron detector by stacking very thin sheets of lithium foil between multiple electrodes. Lithium-based neutron detectors are more cost-effective than helium-3 based neutron detectors.
"The relatively low cost of the detector is a direct result of the advancements in lithium foil manufacturing in the lithium battery industry," Nelson said.
Helium-3 is often used in neutron-based technology, but is rare and expensive, McGregor said. Lithium-6 is a metal that is highly reactive with neutrons and Kansas State University researchers have shown that it is a good alternative for neutron detection.
As a result, the lithium-based detector has several different applications, including stationary detectors that can be used at U.S. ports of entry, mobile backpack neutron detectors, and handheld devices.
"Our lithium-based technology seems to solve many of the problems in neutron detection," Nelson said. "Because lithium is less expensive, we have the capability to make some of the stationary detectors as big as bookshelves, which can help the detectors be even more accurate."
Bellinger, who founded the Manhattan-based start-up company called Radiation Detection Technologies Inc., is helping with the commercialization of the neutron detector. Saint Gobain Corp. also is helping to commercialize the technology.
The engineers have one patent on the research, with another patent pending, and continue to improve the technology behind the neutron detectors. Their work has been supported by the Defense Threat Reduction Agency.

The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
