In his earlier work at Berkeley, he gained intimate knowledge of the behavior of
protons, using the
cyclotron to measure their penetration into various materials.
In a 1946 paper in the journal Radiology, Wilson proposed that contemporary
cyclotrons had almost become capable of energizing
protons that could tackle deep - seated cancers.
Hydrogen gas is injected into the
cyclotron, where static electricity separates
protons from hydrogen molecules.
These souped - up
protons would then be injected into a second, larger
cyclotron, 15 meters across, which would accelerate them further still.
In this plan, near - stationary
protons would be dumped in the center of a small
cyclotron and accelerated by magnetic fields in spirals until they reached the
cyclotron's outer edge.
The
cyclotrons could not match the
proton energies of Fermilab's
proton accelerators, but, partly by operating at a higher power, they would generate a comparable number of antineutrinos per second, and so produce a similar amount of data.
In this project — «PROBE: PROton Beam Extension for Imaging and Therapy» project — a prototype will be built of a novel high - frequency linac that can boost the energy of
protons from the 250 Mega-electron volts (MeV) available from conventional medical
cyclotrons to 350 MeV, sufficient for imaging all patients.
After ruling out all other possibilities, they figured out that the dip was from a phenomenon called
cyclotron resonance scattering, which occurs when charged particles — either positively charged
protons or negatively charged electrons — circle around in a magnetic field.
«If the
cyclotron line is from
protons, then we know that these magnetic fields around the neutron star are extremely strong and may in fact be helping to breaking the Eddington limit,» says Brightman.
Cyclotron resonance scattering creates telltale signatures in a star's spectrum of light and the presence of these patterns, called cyclotron lines, can provide information about the strength of the star's magnetic field — but only if the cause of the lines, whether it be protons or electrons,

protons or electrons, is known.
As Maxwell explains in the video, the original
proton pack consists of a
cyclotron, which is composed of two electrodes that induce the particle to spiral outwards from the center, accelerated by a rapidly varying electric field.
