In a fixed-field alternating-gradient (FFAG) accelerator, eliminating pulsed magnet operation permits rapid acceleration to synchrotron energies, but with a much higher beam-pulse repetition rate.

In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which are normal stresses acting perpendicular to the beam cross-section. We can ...

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.

IOTA, the new test accelerator, gives researchers rich and varied opportunities to dive deep into the physics of particle beams. On August 21, a beam of electrons successfully circulated for the first ...

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 ...

The prototype radiotherapy system combines a fixed vertical radiation beam with horizontal patient rotation. (Courtesy: Paul Liu) Radiation therapy plays a fundamental role in cancer treatment, but ...
