Particle accelerators are powerful devices that use electromagnetic fields to propel charged particles like electrons or protons at speeds close to the speed of light, then smash them head-on. What happens in a blink of an eye during these high-speed collisions can tell us about some of the f...

How do particle accelerators work? The basic particle accelerator is built through placing a particle source (called a proton) at opposing ends of an insulated, evacuated tube (keeping out obstructive air and dust). The polarity between these particles stimulates their movement, in the form of a...
Researchers have long thought pure niobium superconducting radiofrequency cavities were best for particle accelerators. Researchers are now using a toolkit to learn how to add impurities to the cavities to make them smoother—and more efficient. Credit: Thomas Jefferson National Accelerator Facility The ...
How many types of particulate matter are there? What is filterable particulate matter? Is radiation particulate matter? Is particulate matter in soot? What is solid particulate matter? How is a beta particle formed? What percentage of the atmosphere does particulate matter make up? What are three...

Although it's getting a run for its money from the Many-Worlds interpretation lately, many quantum physicists still assume the Copenhagen interpretation is correct. The Copenhagen interpretation was first posed by physicist Niels Bohr in 1920. It says that a quantum particle doesn't exist in one...
How many electron volts are in a cathode ray tube? Why was the cathode ray tube experiment done? How do electric charges produce electromagnetic waves? Does a cathode ray tube shoot an electron? Why is high voltage used in cathode ray tubes?
These high-energy particle accelerators only produce one or two picograms of antiprotons each year. A picogram is a trillionth of a gram. All of the antiprotons produced at CERN in one year would be enough to light a 100-watt electric light bulb for three seconds. It will take tons of...
Among the employed techniques, those based on the use of 'small' particle accelerators are largely used for elemental analysis. In particular, the particle-induced X-ray emission (PIXE) technique has been widely used since its birth for the study of the aerosol composition. For a long period,...
