Astronomers detect beam of energy directed at Earth
An intriguing astronomical discovery has recently come to light, revealing a beam of energy that is directed towards our planet. This beam, its origins, and potential implications for Earth present a ...
Experimental setup showing the two ultrafast silicon detectors used to determine the energy of clinical proton beams. (Courtesy: Anna Vignati) Beam energy is a key parameter in particle therapy, ...
The beam is off, but high energy physics research is very much on at one of the world’s premier particle physics labs. The requirements of social distancing have prompted scientists at the U.S.
This circuit is presented as an alternative to the IR beam break detector featured in the June 2009 issue (Silicon Chip). In order to make it relatively insensitive to ambient light, it uses a ...
