Semiconductor pixel detectors are an important class of radiation and particle detection devices based on semiconductors, such as germanium or silicon (Si). A semiconductor diode is depleted by ...

When studying mysterious subatomic particles, researchers use a different kind of particle detector to prevent run-of-the-mill dust particles from getting in the way. If you’ve got physics on your ...

Alpha particle radioluminescence detection and imaging is an advanced optical technique that capitalises on the light emitted when alpha particles interact with air molecules. When alpha particles – ...

A particle detector being prepared for launch Friday aboard space shuttle Endeavour is intended to answer some fundamental questions about physics, but it has a practical side as well -- testing a way ...

Shifting from giant accelerators 26 km (16 miles) across to brain surgery theaters, a particle detector first developed by physicists at CERN is being used by scientists in Germany to treat brain ...

There is a limit to how big we can build particle colliders on Earth, whether that is because of limited space or limited economics. Since size is equivalent to energy output for particle colliders, ...

A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an evaporating black hole. According to a new theoretical paper, the 2023 ...

A concentration of one part per billion is like a pinch of salt in 10 tons of potato chips—and scientists can now find radioactive particles at concentrations millions of times smaller. In the Journal ...

A combination of X-ray, optical, and infrared data reveal the central pulsar at the core of the Crab Nebula, including the winds and outflows that the pulsars care in the surrounding matter. Pulsars ...
