Editing Magnetic sail (section)

=== Beam powered magsail (BPM) ===
A [[Beam-powered propulsion|beam-powered]] of M2P2 variant, [[Magnetized beamed plasma propulsion|MagBeam]] was proposed in 2011.<ref>{{Cite web |title=MagBeam |url=https://earthweb.ess.washington.edu/space/magbeam/ |website=earthweb.ess.washington.edu}}</ref> In this design a magnetic sail is used with [[beam-powered propulsion]], by using a high-power [[particle accelerator]] to fire a beam of charged particles at the spacecraft.<ref>G. Landis, "Interstellar Flight by Particle Beam," ''Acta Astronautica. Vol 55'', No. 11, 931–934 (December 2004).</ref> The magsail would deflect this beam, transferring momentum to the vehicle, that could provide higher acceleration than a solar sail driven by a [[laser]], but a charged particle beam would disperse in a shorter distance than a laser due to the electrostatic repulsion of its component particles.  This dispersion problem could potentially be resolved by accelerating a stream of sails which then in turn transfer their momentum to a magsail vehicle, as proposed by [[Jordin Kare]].{{Citation needed|date=September 2022|reason=Need citation to reliable source.}}
