you either need very high power or you need to stay in the beam a long time." One such solution that was recently proposed ...

A new proposal uses an electron beam fired from a stable platform near the Sun, which could push a 1,000 kg spacecraft for up to 100 AU (100 times the distance from the Sun to the Earth).

PWFA can reduce the size and cost of such a collider, and ultimately extend the energy frontier of terrestrial particle ... Simulation of a beam-driven plasma wakefield accelerator. The electron drive ...

Most of the paper goes into detail about this, focusing on relativistic electron beams. This mission concept, known as Sunbeam, would use just such a beam. Utilizing electrons traveling at such ...
