A DIFFRACTION pattern was obtained by passing a cathode ray beam through a thin sheet of mica, with an apparatus similar to that used by G. P. Thomson in his interesting experiment on the ...

The goal of this research is to develop an instant turn-on X-ray tube with high speed response. The tube is expected to produce a micro-spot less than 0.5mm at a voltage of 40kV and a current of 1mA.

The Fermi Large Area Telescope (Fermi-LAT) and the Astro-rivelatore Gamma a Immagini Leggero (AGILE) are particle detectors in space which can detect the abandund gamma rays at low energies but have ...
