This has led researchers to consider alternative beam technologies. Charged particle beams, specifically relativistic electron beams, offer unique advantages. Electrons can be accelerated to ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...

Additionally, in extreme astrophysical environments such as pulsar magnetosphere, strong magnetic fields quantize electron perpendicular momentum and strong electric fields accelerate ...
