IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 106 cm. thick) and then received on a photographic plate 10 cm. away and ...

Scientists use non-conventional experiments to prove the existence of a particle Dark matter is believed to make up almost 95% of the universe’s mass. Researchers from the University of Oxford believe ...

A Los Alamos collaboration has replicated an important but largely forgotten physics experiment: the first deuterium-tritium (DT) fusion observation. As described in the article published in ...

Graduate Programs Our graduate programs offer advanced training in physics and astronomy and provide opportunities spanning a wide variety of research and professional areas. Students in the MS ...

The cathode ray oscillograph, since its invention by Braun, has developed along three lines. The major types of tubes are the high voltage tubes with a fluorescent screen, the high voltage tubes with ...

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.

Cosmic ray experiments provided fundamental information on particle physics well before the advent of powerful particle accelerators. Funding for science vanished following the collapse of the ...
