The intricate, hidden processes that sustain coral life are being revealed through a new microscope developed by scientists ...

We present fabrication results and RF cold test of a multiple-electron-beam TWT circuit operating in the millimeter-wave frequency range. Due to the eight beam tunnels and helical waveguide geometry, ...

The electron microscope has higher resolving power than a light microscope and can reveal the structure of smaller objects. This paper describes the development of the lens of an electron microscope ...
