Illustration of a shoebox-sized accelerator. An electron source and buncher/injector feeds into a sub-relativistic DLA (the device described in this article), which accelerates electrons up to 1MeV in energy. These electrons are further accelerated by SiO2 waveguide-driven relativistic DLA, and finally pass through an undulator to produce coherent free-electron radiation.

The fractional quantum Hall effect has generally been seen under very high magnetic fields, but MIT physicists have now observed it in simple graphene. In a five-layer graphene/hexagonal boron nitride (hBN) moire superlattice, electrons (blue ball) interact with each other strongly and behave as if they are broken into fractional charges.

Christmas lights might not be the only thing lighting up these dark December nights, as a solar storm is expected to bring bright northern lights to the Prairies this weekend.Aurora borealis is considered among the greatest natural wonders and scientists say it starts with the sun."The sun is sort of spewing off protons and electrons as a plasma in all directions, all the time, we call that the solar wind," said Bill Archer, mission manager at the Canadian Space Agency. "The magnetic field of the Earth actually forces the…

A new study using nearly eight years of data from the CALorimetric Electron Telescope (CALET) instrument on the International Space Station reports more electrons arriving at high energies than any previous work. Careful analysis of the data bolster understanding of cosmic ray electron acceleration processes within supernova remnants, and suggest one or more local (cosmically speaking) sources of high energy cosmic ray electrons.
