Ultra-stable distribution of timing signals plays a key role in many scientific experiments and research facilities like free electrons lasers or radio-telescope arrays. Timing distribution via optical fiber is convenient and it enables connection of very distant devices separated by distances of hundred meters. Such optical links achieve distribution of RF signals with sub-femtosecond synchronization-level over years. We describe here...

Digitalization of data opens unprecedented opportunities in telecommunication, radar and signal processing. Almost all sensing systems in use today require analog signals to be converted to digital ones. Signal rates have grown at a rate that has outpaced electronic analog to digital conversion (ADC). This demand for higher bandwidth, speed or digitalization precision puts stringent requirements on the aperture jitter...

How Siemens and Semplor democratized SEM and shrank it to fit on a desk. Traditional scanning electron microscopes (SEMs) are large, expensive and complex pieces of lab equipment. To use, maintain and repair them would require specialized knowledge and skills few companies and research outlets have. This didn’t sit well with Semplor, makers of NANOS — an easy-to-use SEM the...

What is the basic idea in quantum mechanics that quantum computers use?Quantum computers take advantage of quantum mechanics, an extremely successful fundamental theory in physics that describes the behavior of very small objects, objects at the atomic level and smaller. The theory states that small objects aren’t made up of solid particles like billiard balls but are fundamentally wavelike. It...

High-resolution electron backscatter diffraction Backscatter electron contrast images (left) and elastic strain (Ɛxx normal strain component) maps (right) associated with the ɣ/ɣ’ interfaces in Ni-superalloy measured by high-resolution electron backscatter diffraction technique. Data were collected from the same area after mechanical polishing and after broad argon ion beam milling. High-resolution electron backscatter diffraction (HR-EBSD) strain measurements are very sensitive to...
