Terahertz accelerators scale up

Artistic impression of a linear relativistic electron accelerator powered by laser-generated, multicycle terahertz pulses. Longitudinal terahertz electric fields propagating through a rectangular dielectric-lined waveguide are phase-velocity matched to the relativistic electron bunches to improve the interaction. The concept could ultimately yield multistaged, high-gradient acceleration of particle beams.

See Jamison et al.

    The manipulation of the quantum properties of light involves its technically challenging strong interaction with matter. Now, an experiment shows that when light propagates through a waveguide it only takes a weakly coupled line of atoms to single out its photons, or bunch them together, unveiling and controlling its quantum nature.
