you either need very high power or you need to stay in the beam a long time." One such solution that was recently proposed uses electron beams accelerated to near the speed of light to propel ...

Among other firsts, the company has integrated a new lightweight, high-strength welding process that will benefit every car made here. New car carriers shuttle the vehicle bodies from station to ...

Weekend travelers must steer clear of the Capital Beltway Inner Loop along Tysons in Virginia these next few days, as the “Big Beam Weekend” road project comes underway. The Virginia ...

China’s government-imposed secrecy allegedly prevented the project scientists from sharing key details, such as the power level of the beam, so it’s hard to gauge the test’s true significance.

“Our 495 Next project crews are going to be lifting some massive bridge beam girders across the 495 northbound beltway to build a new ramp,” said Holland. But there’s a catch for travelers ...

Electron microscopy uses a beam of electrons to illuminate a sample and achieve much higher spatial resolution than light microscopy. Transmission electron microscopy generates an image of the ...

"Something as complex as the DRAs antennas in X-Band, an active antenna that can move the beam electronically and can configure the beam electronically without any movement is what makes this ...

Abstract: This paper describes the electron optics of a practical scanning electron-beam lithographic system (EL1) that provides high-volume direct wafer exposure. The throughput limitation inherent ...

Abstract: This paper presents experimental and theoretical results on focusing a long electron beam with a permanent magnet structure which produces a periodic magnetic field along the axis of the ...
