Seeing the proton beam Top row: relative dose distribution in a water phantom for 200, 207 and 215 MeV proton beams at 32 nA, as measured by radiochromic film. Middle row: MR images showing the ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...

Protons might be stretchier than they should be. The subatomic particles are built of smaller particles called quarks, which are bound together by a powerful interaction known as the strong force. New ...

Proton therapy is an increasingly popular treatment technique that uses beams of protons to accurately target and destroy cancerous tumours. A new Physics World Discovery ebook, Proton Beam Therapy, ...

WASHINGTON, D.C., July 20, 2009 -- Proton therapy -- which uses beams of the subatomic particles to treat cancer -- is a hot topic at this year's American Association of Physicists in Medicine (AAPM) ...

Proton running for 2010 in the LHC at CERN came to a successful conclusion on November 4. Since the end of March, when the first collisions occurred at a total energy of 7 TeV, the machine and ...

Protons can hold an elementary particle heavier than themselves. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Protons may have more "charm" ...

Physicists at York University in Toronto have spent the last eight years meticulously conducting a sensitive experiment to measure the charge radius of the proton in hopes of resolving conflicting ...

Physics is insane, and doesn’t always follow the laws we’ve formulated over the last several thousands of years of accrued observation and analysis. Case in point: a new study published today in ...
