An Air Force Office of Scientific Research-sponsored group of researchers at the University of Michigan have invented a new type of magnetron that could lead to improved radar systems. According to Dr. Ron Gilgenbach at the university, “This invention should make it possible to develop more compact magnetrons that operate at higher power and higher frequencies.” He said the work exploited “some plasma physics principles … as well as an innovative, new geometry to overcome the physical limitations of conventional magnetrons.” (AFOSR report by Rebecca Rose)
The B-2 Spirit remains grounded due to safety issues—and the plane’s stand-down is beginning to disrupt planned operations. According to information provided to the media, the stealth strategic bomber from the 509th Bomb Wing at Whiteman Air Force Base, Mo., was originally scheduled to participate in the latest iteration of…
