... to see electrons, meaning that the accompanying barrage of solar protons doesn’t drown out the electrons in BARREL’s detectors. “Protons create signatures in a very small energy range, while electron ... out, those variations represent the dynamics of only the low-energy protons,” said Gkioulidou. “When we looked at the high-energy proton data from the RBSPICE instrument, however, we saw that they ...

... Center in Houston and Lawrence Berkeley National Laboratory in Berkeley, Calif., has found radiation from protons could further enhance a process that occurs during tumor progression. This information may help lead ... of radiation treatment on the human body. NASA is particularly interested in this research because protons, which are charged subatomic particles, are the main source of space radiation astronauts receive during ...

... other tunnel would contain a 20-Gev electron accelerator whose beam would collide with the proton beam. Such collisions, at energies higher than now available, might provide answers to puzzles that ... electrons; energies achieved in such collisions are lower than those from proton accelerators because the positron is less massive than the proton. A powerful machine of this type operating at Stanford Univ ...

... move through space at almost the speed of light. About 90 percent of them are protons, with the remainder consisting of electrons and atomic nuclei. In their journey across the galaxy ... which atomic particles are responsible for emissions from the interstellar gas clouds because cosmic ray protons and electrons give rise to gamma rays with similar energies. After analyzing four years of ... a short-lived particle called a neutral pion, which is produced when cosmic ray protons smash into normal protons. The pion quickly decays into a pair of gamma rays, emission that exhibits ...
